High Precision TDLG70S Ring Laser Gyroscope
1 Introduction
The ring laser gyroscope (RLG) operates on the Sagnac effect as its foundational principle, utilizing the interference phase difference between clockwise and counterclockwise laser beams within a closed resonant cavity to precisely measure angular increments of the carrier. This type of gyroscope demonstrates high integration level, exceptional reliability, strong environmental adaptability, and stable operational performance, making it a core sensor in high-precision inertial navigation systems widely adopted in both domestic and international applications.
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
Wide dynamic response bandwidth, digital signal output;
Small size, light weight, easy integration and controllable power consumption;
High reliability, shock and vibration resistance, and strong environmental adaptability;
Light path and circuit are encapsulated in one unit, simple structure and easy installation.
