The innovative hybrid deformable mirror concept is expected to eliminate actuator cross talk in electrostatic membrane mirror, while the large stroke (> 300 um) flextensional actuators provide large dynamic range by more than an order of magnitude over the current state of the art. The proposed membrane DM retains the characteristics of membrane mirrors such as light weight, adaptable to large aperture and low cost. Flextensional actuator arrays with stroke of > 300 um will be developed and a hybrid electrostatic/flextensional membrane deformable mirror will be prototyped and characterized. The single crystal piezoelectric actuators produced at TRS offer large stroke, low hysteresis, and an excellent cryogenic strain response. Further investigation on using single crystal piezoelectric actuators in space environment will explore the possibility of using low profile, lightweight, and high performance piezoelectric actuations for positioning, alignment and shape control in space applications.

The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
