Development of a Quartz Fiber Angular Motion Sensor.

Abstract

Progress in the development of the quartz fiber angular motion sensor is described. Magnetic eddy current dampers were evolved which made it possible to operate as an angular rate sensor in the 0.1 to 7 rad/sec bandwidth with a midband frequency of 1 rad/sec. Improvements were made in the photoelectric pickoff and amplifier configuration. The sensor scale factor is 50 mv/deg/hr. Below 0.1 rad/sec, the sensor is an angular accelerometer with a sensitivity of 1 volt/rad/(sec squared). Above 7 rad/sec it is an angular displacement sensor with a sensitivity of 1 volt/sec. Evaluation testing of the sensors is also presented.
