Advanced NANO-40 Micro-Nano Fiber Optic Gyroscope for Accurate Navigation in Challenging Environments

1. Product Overview

NANO-40 micro-nano fiber optic gyroscope (hereinafter referred to as this product) is an angular rate sensor that integrates optics, mechanics and electronics . It is based on the Sagnac effect, integrates a variety of micro-nano fiber optic devices, and realizes the detection process by detecting, processing and feedback the phase difference generated by two beams of light propagating in opposite directions.

This product is mainly composed of optical path components, circuit components and structural components. It has the characteristics of simple structure, no moving parts, no wear parts, fast start-up, small size and light weight. It can be used for carrier posture control and measurement.
