Product introduction
Product Overview
BS-FC24A-300-A1ES micro-nano fiber optic gyroscope (hereinafter referred to as
this
product) is an angular rate sensor integrating optics with analog output,
mechanics and electronics. It is based on the Sagnac effect, integrates a
variety of micro-nano fiber devices, and realizes the detection process by
detecting, processing and feeding back 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, small size, light weight and so on. And can be apply to that attitude control and measurement of the car
Composition
