Project Title:

Deformable Mirror Multiplexer Driver

Electronics

Technical Abstract (Limit 200 words)

For spaced-based adaptive-optics systems the

deformable mirror must be small, rugged, and

lightweight while still delivering stroke and

accuracy exceeding ground-based systems. To that

end, Xinetic's work on high-density deformable

mirrors under a Phase I SBIR demonstrated that

mirrors suitable to these requirments can be built.

The deformable mirror represents only half of a

total system, however. The driver electronics must

also deliver high-accuracy in a small package

suitable for satellite applications. Current driver

systems fill a 7' rack, weigh over 400 pounds, and

dissipate multiple kW's of heat for a 349-channel

system. For the 16,000 channel systems envisioned

for NGST we need much lower frequency response

but they must be highly efficient designs. To satisfy

these requirements Xinetics proposes a digital

multiplexer driver system. By taking advantage of

the unique dielectric characteristics of the Xinetics

PMN actuators and digital multiplexer circuits we

can generate a small, high efficiency electronic

system which can fit in a single chassis. The

multiplexer will use a single amplifier channel along

with a digital switching system to send commands to

the individual actuators in a raster mode. In this

way hundreds or even thousands of channels may

be contained on a single driver board.
