ATA is developing a complete line of fine steering mirrors, bringing new
meaning to the word “fast,” that enable real time corrections in adaptive
optics for directed energy systems, long range dynamic laser
communications, and telescopes.
Our FSMs can be space qualified. We offer designs using any mirror
technology from metal and glass to silicon carbide and new silicon carbide
foam structures such as the Schafer SLMSTM technology to meet your
specific program requirements. Mirror sizes range from 1.5-inch high
performance laser communications mirrors and proven 5-inch 1KHz designs to
new 12-inch custom designs operating at 1 KHz and higher for high energy
laser directed energy systems.

What makes ATA beam
steering exceed the performance of fast steering mirrors from other
companies? The ATA developed and manufactured sensors, actuators, flexures
and controls.
ATA produces the highest efficiency actuators available, including space
qualified actuators with redundant core windings. New ATA designed
non-contact linear displacement sensors are capable of the lowest noise
floors and sub-nanometer resolution over 1mm and longer travel, and
beveled edges to match mirror rotations. ATA also makes the finest angular
rate sensors available anywhere, with angular motion measurement
capabilities below 40 nano-radians, 1 to 1000 Hz. Combine these
capabilities with our 30 year history of excellence in real time controls
and system development for precision sensing, measurement and control and
you have a product line that simply beats the competition.
ATA develops and
manufactures stabilized platforms and inertial reference units which can
be combined with fast steering mirrors to meet the most stringent system
requirements. |
