Optical line of sight pointing and stabilization system
First Claim
1. A system for stabilizing an optical line of sight comprising:
- an optical system including primary optics and relay optics;
a jitter rejection mirror located in the path of said relay optics;
a jitter reaction system for maintaining alignment of said jitter rejection mirror in response to a control signal;
an auto alignment sensor for detecting jitter in a laser reflecting from said jitter rejection mirror, and generating a control signal for said jitter rejection system for reducing said jitter; and
a stabilized source of reference laser which is received by said primary optics and relayed to said jitter rejection mirror and to said auto alignment sensor, whereby an optical system jitter error signal is produced for controlling said jitter rejection system.

Abstract
A system for stabilizing an optical line of sight. An optical system including primary optics and relay optics includes a jitter rejection mirror located within the path of the relay optics. An auto alignment system is provided for maintaining alignment of the jitter rejection mirror in response to a control signal. An auto alignment sensor detects jitter in a reference beam passing through the jitter rejection mirror, and the generated control signal is used to reduce the jitter. The reference beam is supplied by a stabilized source of laser signals which are received by the primary optics, and relayed to the jitter rejection mirror.
