Product Details
SG-30 single-axis fiber optic gyroscope is an all-solid-state high-precision digital closed-loop medium-low single-axis fiber gyroscope that integrates optics, machinery and electricity. Based on SAGNAC principle, it is composed of SLD light source, optical fiber coupler, photoelectric detector, integrated optical phase modulator, optical fiber sensing ring, circuit and structures.
It is designed for servo stabilization platform with the features of small volume, high update rate, low delay, low noise, high bandwidth and so on. It is the ideal choice of medium and low precision angular rate sensor and can be used widely in various types of stable platform.
Features
- Single 5V power supply
