PROJECT SUMMARY
Proposal Number:
Project Title:
COMBINED FAST-STEERING AND ALIGNMENT MIRROR FOR SPACE-BASED INTERFEROMETRY
Technical Abstract:
The proposed product development will create a higher
performance 80 by 60 mm fast-steering mechanism (FSM) that
combines the functions of fast-steering and alignment at the
cost of each unit alone. High-bandwidth operation is combined
with large angular travel and increased load capability. This
is accomplished by two innovations: the first is a simpler,
more robust flexure suspension with additional angular travel
and less fixturing. The second is an actuator modification
that allows a highly efficient actuator concept, formerly used
only on smaller FSMs, to be used on larger mirrors, resulting
in improved acceleration, mass and power.
Direct benefits include:
* fewer mechanisms and control electronics,
* increased lateral load capability allows launch without mechanical
caging,
* simplified design reduces fabrication cost,
* lignter mechanism consumes less power.
Phase I objectives are to verify mirror surface figure accuracy
and actuator performance by analysis and engineering model
fabrication. A FEM stress analysis of the mirror with
attachements will predict the effects of magnet and flexure
attachment. Flexure stress analysis will verify lateral load
capability predictions. Engineering model fabrication and
testing will validate the FEM mirror model, verify performance
of the actuator concept, and verify flexure fabrication,
assembly techniques, and attachment distortion.
Potential Commercial Applications:
include ophthalmic imaging,
ophthalmic surgery, optical communications, ground-based
astronomy, hand-held, shoulder- and vehicle-mounted cameras for
movie and broadcast television, rapid IR inspection of electric
utility equipment from moving trucks or helicopters, Coast
Guard surveillance, hand-held or helicopter police cameras and
photo-lithography.
