Wide Angle Intensity Pickoff.
Abstract
Angular measurement systems are utilized to indicate changes in angular position between reference points such as a stable reference point and an unstable reference point. Typical of such a system is a moving vehicle or missile following a preselected path. A pickoff system for use with angular measurement systems that has both a very fine signal resolution and accuracy over a wide angle. The fine signal resolution allows accurate detection of incremental changes. The wide angle of operation provides a minimum linear range of 70 deg, with a total range of 180 deg when the nonlinear range is included. An optical source and detector are mounted on unstabilized structure with the optical source purposefully misaligned with the detector. A fiber optic bundle is positioned on a stabilized structure and provides an optical path between the optical source and detector for providing a variable signal there through in response to angular position changes between the unstabilized structure and the stabilized structure.
