ABSTRACT:
A ring laser gyroscope functions both as a standard gyroscope and as an accelerometer. As the ring laser gyroscope experiences acceleration along its input axis, the frame bends and position sensing photodiodes are utilized to detect the optic axis motion and laser beam intensity. By measuring optic axis shifts along the gyro input axis during acceleration, a signal proportional to acceleration is obtained.
