Abstract
The ACCELERATION DISTORTION RESISTANT RING LASER GYRO (RLG) (10) shown here includes a control mirror (12) subject to distortion beyond the path length control capabilities of the RLG (10) when subjected to intense translational acceleration in the direction (20) perpendicular to the face of the control mirror (12). An anti-parallel compensating mirror (14) is provided to offset the path length change. Additional design flexibility may be obtained by replacing the compensating mirror (14) with a compensating group of mirrors.
