[origin: WO9904221A1] Ring laser gyros have mirrors that allow signals to leave the ring laser gyro and provide information about the status of the ring laser gyro. The wedge mirror (2), which is one of these mirrors, is aligned such that the signals leaving the ring laser gyro from this mirror will provide accurate ring laser gyro information.
