<p>An optical sensor comprises a device for monitoring the angular motion of a remote body about three orthogonal axes from a single observation point. A compact totally passive target is adapted to be attached to the body, the angular motion of which is to be sensed. The target reflects light beams representing pitch, yaw and roll measurement functions. The reflected light beams are optically sensed and reduced to components about the pitch, yaw and roll axes which are visually displayed through a single eyepiece.</p> |
