Product Description

GSGYR202F Fiber Optic Gyroscope

Product Introduction

The GSGYR202F is an inertial angular rate sensor based on the optical Sagnac effect, designed to measure rotational angular velocity along its sensitive axis. It features a digital closed-loop detection circuit that extracts optical path differences between clockwise and counterclockwise light propagation, enabling real-time angular velocity detection through modulation, demodulation, and closed-loop feedback control.

Key Features

Consists of optical angular velocity sensing unit and signal detection unit
Provides dual-axis angular increment information and internal temperature data
Digital closed-loop detection for precise measurements
Real-time angular velocity signal detection

Main Components

Optical path unit: SLD light source, optical fiber coil, integrated optical phase modulator, optical fiber coupler, and photodetector
Circuit unit: Light source driving circuit, signal detection and control circuit
Structural components: Gyroscope housing and mounting elements
