Paper Abstract

A laser diode measurement concept is described that can be effectively used in a helmet mounted sight system; it offers a factor of 5 resolution improvement over conventional optical sensing techniques. It also has no moving parts and eliminates the compensation problems associated with helmet mounted metal in magnetic approaches. In the laser helmet mounted sight approach, the feedback from a helmet mounted reflector interacts with an airframe mounted diode to form a 3 mirror laser cavity; this semi-conductor laser cavity technique is used to provide 20 micrometers range resolution for the triangulation of fixed reflection points on the helmet. Geometric and radiometric models have been developed that show the feasibility of this approach. Geometric models include a discussion of resolution requirements. Radiometric models include a discussion of the laser cavity conceptual approach and a performance analysis of resolution and detectability.
