ABSTRACT:
A screening device can be used to test ring laser gyro performance at numerous points during the gyro assembly. This performance testing can be done without physically attaching electrical connections thereto and at a point prior to the attachment of readout sensors and/or dither motors. This screening device provides a valuable tool in identification of problems related to gyro performance which may be incurred during the assembly of the gyroscope.
