Abstract
A system for detecting radiation events in a ring laser gyro is provided. The system includes one or more photodetectors, that produce photocurrent signals to monitor the ring laser gyro. Further, the system includes one or more comparator circuits actuating at one or more thresholds. The one or more comparator circuits are responsive to the photodetectors to detect when a radiation event occurs based on the photocurrent signal. The system further includes a path length control circuit responsive to the one or more comparator circuits, that restores operating conditions for the ring laser gyro when a radiation event occurs.
