TECHNICAL ABSTRACT (LIMIT 200 WORDS)
Using existing technology, high-accuracy precision 2-axis fine-steering mirror (FSM) applications are limited to position sensors with 0.4 to 1.0 urad resolution. A number of applications, such as JPL?s optical communication programs require 0.1 urad resolution.
Three recently developed commercial off-the-shelf (COTS) sensors have inherently better resolution, but have not been proven in FSM applications and are not qualified for space flight.
In most cases these devices are sufficiently compact to be integrated with even the smallest FSM with reasonable size increases.
The proposed innovation involves the use of one or more of these advanced sensors to achieve a factor of 2 to 5 improvement in resolution for space-based FSM applications.
The proposed innovation is an approach to integrate these recently developed advanced base-referenced position sensors into space-qualified FSM designs. The significance for NASA involves achieving reduced cost and risk for high-accuracy JPL applications like
high-rate inter-planetary optical data transmission and interferometry with improved resolution.
LHDC will complete integrated sensor FSM concept designs for the FO15-61, FO35-52 and FR150-35 FSM suitable for use in engineering model manufacturing and testing in Phase II along with estimates of manufacturing capability.

POTENTIAL COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
Primary Department of Defense applications include directed-energy weapons, optical communication, surveillance, rendezvous/docking optics, chemical detection, and others.
Other non-government commercial applications include optical communications, ground-based observatories and precision manufacturing.

POTENTIAL NASA APPLICATIONS (LIMIT 150 WORDS)
Primary NASA applications include optical communication, interferometry, earth observation, space-based observatories, rendezvous/docking optics, and others.
