Model F70L-M High Accury Single-axis Fiber Optic Gyroscope With 0.05 °/hr Bias Drift

 

1. Product Introduction

 

1.1 Working Principle and Function

This product is an inertial angular rate sensor based on the principle of Sagnac effect, which is used to measure the angular rate movement of the carrier around the sensitive axis of this sensor. This unit takes the fiber optic coil as the angular rate sensitive unit and the closed-loop detection circuit as the basis.

Two beams from a laser are injected into the same fibre but in opposite directions. Due to the Sagnac effect, the beam travelling against the rotation experiences a slightly shorter path delay than the other beam. The resulting differential phase shift is measured through interferometry, thus translating one component of the angular velocity into a shift of the interference pattern which is measured photometrically.

Beam splitting optics launches light from a laser diode into two waves propagating in the clockwise and anticlockwise directions through a coil consisting of many turns of optical fibre. The strength of the Sagnac effect is dependent on the effective area of the closed optical path: this is not simply the geometric area of the loop but is enhanced by the number of turns in the coil.

This product is an inertial sensor composed of optical system, corresponding power supply and data processing circuit. It can provide three-axis angle increment information.

 

1.2 Configuration

The product is mainly composed of the following components:


a) Optical part: light source, coupler, Y modulator, fiber coil, detector;


b) Circuit part: processor board, light source board and preamplifier;


c) Structural part: body, cover, etc.

1.3 Shape and Installation Dimensions

The bottom of the shell is a tangential square with a shape size 70mm × 70mm ×32mm. Four 4.2 mounting holes are distributed at the four corners of the tangential square with a pitch of (62 ±0.1 mm) × 62 ±0.1 mm. The bottom of the shell is a gyro mounting plane with a flatness less than 0.01.
