Fiber Optical Angular Rate Sensor Small FOG
Product Overview
MFOG-24 micro-nano fiber optic gyroscope (hereinafter referred to as this product) is an angular rate sensor integrating optics with digital 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 carrier.
