Description
Single Axis Fiber Gyro Low Power Fiber Optic Gyro Imu Angular Rate For Navigation

This document specifies the requirements and methods for the use and maintenance of FOG-60 fiber optic gyroscope (product for short).
Product introduction
1   Working principle, function and scope of application of the produc
1.1   How it works This product is an inertial angular rate sensor based on the optical Sagnac effect, which is used to measure the angular rate of the carrier along the sensitive axis of the product. The angular rate sensing unit of the product is an optical fiber ring, and a digital closed-loop detection circuit is adopted to extract the optical path difference of clockwise and anticlockwise propagating light caused by the external physical angular rate, which is sensed by the optical fiber ring,At the same time, the voltage signal converted from the optical path difference signal is used for closed-loop feedback and control to realize the modulation and demodulation of the signal and achieve the purpose of angular velocity signal detection.
1.2   Function This product is composed of an optical angular velocity sensing unit and a signal detection unit, providing single-axis angular increment information and internal temperature information.
1.3   Scope of application The products are mainly suitable for applications such as medium-precision inertial navigation systems, positioning and orientation systems, and servo stabilization systems.
2   Composition The main components of the product are as follows: a)   The optical path unit comprise an SLD light source, an optical fiber re, an integrated optical phase modulator, an optical fiber coupler and an optical detector; b)   The circuit unit comprises a light source driving circuit and a detection and control signal circuit board; c)   Gyroscope structural parts.
3   Appearance and installation dimension Overall dimension (mm): (60 ± 0.1) × (60 ± 0.1) × (31 ± 0.1) (L × W × H); Installation dimension (mm): (50 ± 0.1) × (50 ± 0.1) (L × W), Φ3.2mm × 4,
