Description

A Laser Gyro Based on Longitudinal Radio Frequency Discharge technical field The utility model belongs to the laser gyroscope technology and relates to a laser gyroscope based on longitudinal radio frequency discharge. Background technique Laser gyro is a kind of angular velocity sensor, which generally adopts a ring laser, and its gain method often adopts a high-voltage DC discharge method. Miniaturization is a development trend of optical gyroscopes. However, when the cavity length of laser gyroscopes becomes smaller, the conventional DC discharge method is difficult to meet the gain requirements, and DC discharge will cause output errors of laser gyroscopes. In addition, key components such as diaphragms and light combining devices commonly used in laser gyroscopes require high processing and installation tolerances and high costs, making it difficult to meet the application requirements of micro-miniature laser gyroscopes with cavity lengths within 40mm. The existing...
