Boston Micromachines Wins NASA Grant

Mar 2011
CAMBRIDGE, Mass., March 8, 2011 — Boston Micromachines Corp. (BMC) announced Monday that it had received a $100,000 Phase I SBIR contract from NASA to support space-based imaging research.

The Phase I project is for the development of a reliable high-resolution, fault-tolerant microelectromechanical deformable mirror (MEMS-DM) technology that will fill a gap in NASA’s road map for future coronagraphic observatories. To achieve this, BMC will implement two complementary modifications to the manufacturing process.

First, the team will develop a drive electronics approach to limit actuator electrical current density generated to prevent permanent failure when a short-time-frame, single- fault failure occurs. Secondly, team members will modify the actuator design to mitigate failure due to adhesion between contacting surfaces of the actuator flexure and fixed base.

Boston Micromachines provides advanced MEMS-based mirror products for commercial adaptive optics systems.

GLOSSARY
adaptive optics
Optical components or assemblies whose performance is monitored and controlled so as to compensate for aberrations, static or dynamic perturbations such as thermal, mechanical and acoustical disturbances, or to adapt to changing conditions, needs or missions. The most familiar example is the "rubber mirror,'' whose surface shape, and thus reflective qualities, can be controlled by electromechanical means. See also active optics; phase conjugation.
