High Precision TDLG50S Ring Laser Gyroscope
1 Introduction
Ring laser gyroscope to the Sagnac effect as the basic principle, through the detection of laser in the ring glass cavity interference phase difference measurement carrier angle increment, this type of gyroscope integration, reliability, environmental adaptability, stable performance, is currently the most commonly used at home and abroad high-precision inertial navigation equipment, the core sensor.
2 Application
Suitable for inertial navigation equipment and attitude reference equipment in high-end fields such as spaceships, airplanes, artificial satellites, vehicles, ships, submarines and so on.
3 Characteristics
Light path and circuit are encapsulated in one unit, simple structure and easy installation;
Small size, light weight, easy integration and controllable power consumption
High reliability, shock and vibration resistance, and strong environmental adaptability;
Wide dynamic response bandwidth, digital signal output.
