Boston Micromachines successfully delivered the world’s first fully-functioning 2K-DM to NASA’s Jet Propulsion Laboratory (JPL) as part of NASA’s Phase II Small Business Innovation Research (SBIR) program! With 2040 actuators, this mirror will be a contributing element to the BMC’s goal of developing DM technology for next generation space-based telescopes for exoplanet imaging.

What is even more exciting is that the NASA SBIR program has decided to extend our contract into its Phase II-X program in which BMC will deliver additional deformable mirrors for evaluation and potential inclusion in the Wide Field Infrared Survey Telescope (WFIRST) program. The WFIRST program is a NASA mission concept of a next-generation space telescope that will play a role in the next steps of exoplanet and dark energy research for astronomers and scientists. This is scheduled to launch in the mid-2020s. Check out more here.

 This project has provided BMC the experience and the opportunity to begin the first steps towards the production of even higher actuator count DMs, 8,000 actuators or more, for space-based and ground-based telescopes.

I attended the SPIE Astronomical Telescopes and Instrumentation event in Austin, Texas recently and while I enjoyed the music and incredible bar-b-que,  I thought it might be a good idea to summarize what I learned and the most interesting things mentioned about adaptive optics research.

Exoplanet research is alive and well

I am happy to say this.  We have been developing bigger and better mirrors for both ground-based and space-based telescopes here at BMC and they are targeted specifically for this use.

Here are the programs which I heard the most about last week:

MagAOX

Our 2K-DM will be shipping soon to the folks at the Magellan Telescope working on MagAOX, their planet-finding instrument. And, we have been discussing the design of gthe next generation instrument for the Giant Magellan Telescope, GMagAOX, which includes no less than seven 3K-DMs totaling over 21,000 actuators to be used for an order-of-magnitude higher level of control.  Logo Credit: Kyle Van Gorkom, University of Arizona

While I am sad to see the Gemini Planet Imager instrument mission end at the Gemini South Observatory (which includes our 4K-DM), I am excited for the next phase that is set to begin at Gemini North in Hawaii.  The location study is ongoing and will yield which components will get an upgrade.  While I am always excited about delivering a newer, better DM, I am proud of the performance of the 4K-DM and would be just as happy if that workhorse kept on running!

SCExAO just  keeps on going.  That is all.

SCExAO 2K DM

Seriously, though.  The expected science yield from this instrument is extremely exciting and I look forward to seeing more images in the near future!  Check out their site hereImage credit:  Olivier Guyon, University of Arizona

Finally, on the space-based front, Habex and LUVOIR designs are in motion and both are baselining BMC’s technology for the final design. Click the link here to see a recent article about AO and see a picture of the layout of our biggest mirror, the 8K-DM.  I have a quote 😊.

Don’t forget about all of the other science!

There is so much else going on and I couldn’t possibly list it all. Work at Lawrence Livermore National Labs is ongoing to develop an extremely low latency AO system called “LLAMAS.” Small(ish) telescopes are utilized as well to do some amazing data collection. I would be remiss if I didn’t mention Robo-AO which is now in the process of moving from Kitt Peak to the UH88 telescope in Hawaii.  And, Robo-AO2, otherwise known and the Rapid Transit Surveyor, is in the midst of design and build and will be online soon.

Final thoughts

The astronomical instrumentation field is alive and well and adaptive optics has become an integral part of almost all of the major installations in service, being built or being designed.  We are excited for the field and especially proud to be involved in the programs that required our high speed, high resolution devices to push science forward! 

Robo-AO: At Kitt Peak and Beyond

Multi-DM_Compact_Mount.pngI’d like to recognize the Robo-AO team at Mt. Kitt.  They have done a great job of transferring the instrument from Palomar and within a short time, got a season of imaging in, resulting in a number of papers and posters that were presented at  SPIE Astronomical Telescopes and Instrumentation. We’re really excited to hear that they are back up and observing after the monsoon season.  I’m sure we will be getting some more great results from the team.  For those who don’t know, Robo-AO is “the first autonomous laser adaptive optics system and science instrument operating on sky. The system robotically executes large scale surveys, monitors long-term astrophysical dynamics and characterizes newly discovered transients, all at the visible diffraction limit. The first of many envisioned systems has finished over 180 nights of science observing at the Palomar Observatory 60-inch telescope (with over 19,000 robotic observations executed)”. In 2015 it was moved from Palomar to Kitt Peak National Observatory in Arizona.   Boston Micromachines is proud to have worked with the Principal Investigator, Christoph Baranec, on a small part of this instrument, as the deformable mirror chosen for this back in 2009 was a BMC Multi-DM (pictured). 

What You Missed this Month in the Adaptive Optics Industry

If you've been hiding out in the lab, constantly checking your March Madness bracket, or escaping the cold to find any ounce of warmth (like me!), chances are you may have missed some exciting news. March turned out to be quite a busy month in the Adaptive Optics world, so here’s what you missed:

1. Exoplanet imaging in under a minute

At the recent AAAS 2015 annual meeting, Bruce Macintosh from Stanford University and Principal Investigator for the Gemini Planet Imager (GPI), discussed that there are over 1,000 confirmed planets due to the help of Adaptive Optics. In order to start really understanding a planet and its characteristics, you need to look at the composition of its atmosphere. Astronomers have relied heavily on the adaptive optics technique, allowing for distortion correction of the atmosphere using a deformable mirror. This has had proven success in regards to GPI, which uses a BMC deformable mirror (4K-DM), as part of its adaptive optics system. It can image planets in about a minute, which used to take up to an hour! GPI recently imaged the HR8799 star system, with three orbiting planets. Since November 2013, GPI has imaged 600 stars and identified 50-60 new planets.

2. 2nd quadruple star system discovered 

More exciting news from the Astronomy world was the discovery of a massive planet with a quadruple star system only 125 light-years from Earth. Discovered by the Jet Propulsion Laboratory, they were able to detect the fourth star after fitting the telescopes at the Palomar Observatory with a Robo-AO adaptive optics system. Utilizing the AO technique allowed astronomers to pick up on the faint star that couldn’t be seen before. Below is a diagram illustrating the discovered Ari 30 alongside its pair in a binary systems. Before this detection, only one other planet in a quadruple star system had been discovered before. More sightings are being predicted as exoplanets are found, with the help of Adaptive Optics systems of course!Ari 30 system resized 600

3. The most valuable brains 

Congratulations to Scientists Winfried Denk, Arthur Konnerth, Karel Svoboda and David Tank for being awarded the world’s most valuable neuroscience prize, The Brain Prize, for the invention and development of two-photon microscopy! Two-photon microscopy is helping researchers to understand the human brain and how its networks process information, such as nerve cell communication. It has also enabled the study of nerve cells that control vision, hearing and movement. Recent work has been carried out to implement adaptive optics systems on two-photon microscope systems around the word, including locations such as the Howard Hughes Medical Institute, Institute Langevin at CNRS and Boston University. Standing on the shoulders of giants to improve imaging of the brain with AO!

Now that you are caught up with some of the biggest achievements using Adaptive Optics this past month, check out all of our deformable mirror products that are used in AO instruments like GPI on our website.

What Do You REALLY Want in a Deformable Mirror?

Posted by Michael Feinberg on Wed, Oct 17, 2012 @ 04:00 PM

Tags: deformable mirror, adaptive optics, response time, astronomy, laser science, mirror technology, microscopy

This past summer, Boston Micromachines Corporation conducted a survey of nearly 300 members of the business and scientific community to find out what features were valued in a deformable mirror for adaptive optics and other wavefront correction applications.  Respondents came from our three major vertical markets: microscopy, deformable mirror survey resized 600astronomy and laser science.  In this survey, we asked some fundamental questions and had respondents choose between three DMs with properties varying in categories of actuator count, stroke, response time and price in various combinations. We were able to drill down to what each respondent valued.  Here are some of our key findings:

1)      Actuator count was the most valued property

Across all verticals, this was true.  Overall, respondents preferred an  average of 1000 actuators. While microscopists preferred 140 actuators by almost 2 to 1 over other models, those who identified as laser scientists were looking for an average of 1001 actuators and astronomers preferred, on average, 1800 actuators.

This was very interesting to us considering we are the only player in the market to provide deformable mirrors with these actuator counts as standard products or are developing DM systems which meet these specific needs (we have a 2000 element mirror in the works).

2)      High speed is important

The most frequently chosen option for response time amongst laser scientists was 50μs and all other disciplines preferred average response better than 300μs. This is great news for the industry considering that most mirror architectures can respond adequately to meet the needs of the users. Our DM architectures are available with response times up to 22μs and we are able to drive these mirrors with our X-Driver (response time down to 4μs), satisfying high speed requirements as well.

3)      Low price is desired

As we hear so often, most users were looking for low-priced devices. This was the second    preferred property after actuator count. While those of us in the industry talk about lower prices with higher volumes, the volumes just haven’t been there yet to make this prophecy come true.  The hope in the future is that the DMs based on scalable technologies, such as MEMS, will take off and lower-priced devices will be available.

We definitely learned a lot from this survey, above and beyond what is mentioned above.  If you have any questions about our methods or are interested in discussing more specifics about the responses, I would be glad to chat further.  Just contact me at support@bostonmicromachines.com.

 

CLEO 2012: Concentrated Interest in Adaptive Optics

BMC at CLEO

This year, the CLEO Conference had its normal interesting character:  A variety of users from hardcore laser scientists to focused business interests to laser scanning imaging folks.  BostonMEMS Optical Modulator Micromachines took our position within the Thorlabs booth for the 5th year(thanks again, guys!) and demonstrated some great technologies that we think will make an impact in the industry.  Our MEMS Optical Modulator  generated a fair amount of interest and prompted some great questions about its capabilities and possibilities.  We showed its flexibility by demonstrating how with a simple input signal and an amplifier, a reflective diffractive element can be used to couple light into a fiber at varying frequency and amplitude.  We went into the show thinking this would be the big topic of conversation.  While we did have some great conversations and we’re more than happy with the response, the real star of the show was our Wavefront Sensorless Adaptive Optics Demonstrator for Beam Shaping. Users from all walks of the laser industry approached me with potential uses from wavefront characterizationWavefront Sensorless Adaptive Optics Demonstrator techniques to photon counting.  I learned that the simplistic nature of the kit (maximize a signal through a pinhole) allows researchers with very different backgrounds to think of interesting ways to take advantage of its versatility.  We found that the simple, clear spot on the screen was enough to entice microscopists and laser scientists alike to brainstorm interesting ways in which to integrate the deformable mirror, detector and algorithm of the system into their latest work.  I am looking forward to some great follow-up conversations!

I did get the chance to venture out of the booth for a few talks as well as touch base with some new and old friends.  Major impressions:

1)      AO is still not a major player in laser science

While there were some interesting topics and uses of deformable mirrors and spatial light modulators, the technique is by no means pervasive as in other industries such as astronomy or biological imaging.  Other techniques such as MIIPS (congratulations again, Dr. Dantus) serve the industry and are well proven to be able to satisfactorily shape pulses. Another theory:  Laser scientists prefer to go after the laser for improvements instead of supplementary hardware.  This could be for a variety of reasons such as: a) extra hardware means lost light, b) this is where they are comfortable and love to tweak things or c) the cost is just too high right now.

2)      Beam characterization is becoming more affordable

With a few companies introducing higher speed and lower cost wavefront sensors, the market is becoming more accessible to more researchers.  This can only be good for everyone.

3)      Booth traffic is down, but more focused

In past years, my conversations were usually an even split between educating the visitor about the basics and having in-depth discussions about the capabilities and possibility of integrating devices into optical systems.  This year, the split was more like 75/25 in favor of detailed discussions.  Many are well aware of the background and of the 75%, at least half approach me with well thought-out ideas.  It is very refreshing and encouraging to have these discussions and I suspect the ratio will continue to grow as years go by.

Overall, it was a productive show.  I look forward to returning to San Jose next year and introduce exciting products that we have in our product roadmap and get more people to shape their light!

Deformable mirrors in space???

Boston Micromachines has been awarded US$ 1.2M in contracts by NASA's Small Business Innovation Research Program (SBIR) to support space-based astronomy research.  Now, one might wonder, considering this is astronomy, “why is anyone spending any money to develop deformable mirrors for use in space telescopes looking out at the stars?  I thought that deformable mirrors were used to remove aberrations introduced by the atmosphere.  There’s no atmosphere up there!”

Well, you’d be right:  There is no atmosphere up there.  But, there are aberrations:  In the optical system.  When systems are designed, none of them are completely perfectly aligned. There’s no such thing.  But, when you’re looking for planets around stars in other galaxies, you need things to be well aligned.  VERY well aligned.  So, to compensate for any misalignments introduced either during transit to space or thermal variations in the instrument, you can use a deformable mirror as part of an adaptive optics system.  So, for this, we are designing a 1021 segment (3063 actuator), tip-tilt-piston deformable mirror.  It is the largest ever designed of this type and is expected to be used as part of a coronagraph telescope for exo-planet research.

Two other things to worry about are power and weight.  In satellites, there is a very limited amount of power, and the weight greatly affects the cost to put the satellite into orbit.  In terms of the mirror, MEMS has that taken care of:  The power is extremely low and the weight is many orders of magnitude lower than traditional piezo-electric-based mirrors.  So, the other half of the equation is the drive electronics.  As part of this research, BMC is designing multiplexed drive electronics which will reduce the size and weight significantly and lower the power even further.

You put the two parts together, mirror hardware and drive electronics, and you have a low-cost, low-power, lightweight solution for the most cutting edge astronomy research going on right now.

If you have any questions, please contact me directly:  I would be happy to talk about these products or refer you to the folks who are attacking this challenging problem.
