1 Introduction
1.1 Product Review
MFOG-910 fiber gyro (hereinafter referred to as this product) is an angular rate sensor integrating light, mechanical and electrical. Based on the Sagnac effect, it integrates a variety of highly reliable micro-nano fiber devices to achieve the detection process by detecting, processing and feedback the phase difference generated by two beams of light propagating in the opposite direction. This product realizes ultra-high rotational speed measurement through the redesign of optics, structural support, and control algorithms.
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, impact resistance, fast start, small size, light weight and high reliability. It can be applied to the control and measurement of motion carriers.
