Abstract

A Fast Steering Mirror (FSM) is a mechanism that directs an optical beam between a source and a receiver using a reflective surface. Applications involving target detection and tracking require rapid scanning and slewing to maintain the line of sight (LOS). These mission requirements define the performance of a mechanism that offers precise pointing capability and a high level of disturbance rejection capability. Ball Communication Systems Division (BCSD) has developed, tested and delivered reactionless fast steering mirror/scanners (see Figure A-1) that were designed for use in an airborne tactical environment. These mechanisms direct, scan, and stabilize a two inch optical beam over a total angular range of eight degrees in a triangular scan profile at a frequency of fifteen Hertz. The absolute position of the mirror is linear to within plus or minus forty microradians within the eight degrees of angular travel and to within thirty-four microradians for ninety percent of the triangular wave profile while scanning. This paper will discuss the overall mechanical and electrical design as well as present data illustrating the performance of the FSM.
