NANO-40 Micro-Nano Fiber Optic Gyroscope
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.
2. Composition
The product is mainly composed of the following components:
a) Optical path components;
b) Detection and control signal circuit board;
c) Optical fiber ring skeleton, shell and other structural parts;
3. Appearance and size
The product is cylindrical, with dimensions of φ 40 mm × 20.5 mm, and three M 3 threads on the bottom surface for connection to the outside.
