Laser gyroscope detector and path length control system |
摘要 |
A four frequency laser gyroscope system having parallel processing of path length control and detection signals. Two output signal beams each containing components of two of the four waves circulating in the laser cavity are shone upon separate detector diodes. The output signals from the diodes contain both high and low frequency components which are separated in a crossover circuit. The low frequency component is processed to control the optical path length while the high frequency component is processed to produce a digital signal representing the amount of rotation of the laser gyroscope cavity.
