An Investigation of a Laser/Interferometer Attitude Monitoring Device

Abstract

A laser beam referenced, Fabry-Perot type, angle sensing interferometer for precise inertial platform attitude monitoring was designed, analyzed and tested. Analysis indicated an angular sensitivity of 0.1758 fringes per arc second with an estimated accuracy of = 0.285 arc seconds. The non-optimized device tested was satisfactory with respect to full field interference quality and signal characteristics. Angular sensitivity data showed good agreement with theory. Calibration data deviations from theory were greater than the estimated experimental accuracy. The probable cause of the poor agreement was the phase shift effect observed but not investigated. Several possible causes of this effect were discussed.
