A test program to evaluate laser gyros for Air Force applications is described. The test plan development, facilities and actual test results obtained at the Charles Stark Draper Laboratory, Inc. on a mechancially dithered laser gyro are presented. The test plan addresses methods to evaluate a laser gyro's bias and scale factor under various environments and operational modes. The test techniques are designed for use with: a mini-computer for on-line data analysis and test control, a thermal chamber mounted on an air-bearing table which allows performance evaluation with temperature profile testing, and a data acquisition system for recording available analog voltages for subsequent correlation analyses. Future test plans and additional areas for evaluation are also discussed.
