A high-precision dual-axis fiber optic gyro micro-measurement device

Abstract

The invention discloses a high-accuracy dual-axis optical fiber gyroscope micro measurement device which comprises a gyroscope platform, optical fiber gyroscope ring body assemblies, a light source assembly and a gyroscope control board assembly. Two optical fiber gyroscope ring body assembly mounting planes are respectively formed on the outer wall of the gyroscope platform; one optical fiber gyroscope ring body assembly is respectively mounted on each optical fiber gyroscope ring body assembly mounting plane; each optical fiber gyroscope ring body assembly comprises a ring body cover, a ringbody seat, a Y waveguide and a platinum resistor temperature sensor; the light source assembly and the gyroscope control board assembly are also respectively arranged on the outer wall of the gyroscope platform; the bottom of the gyroscope platform is of an integrated structure and is provided with four driving motor mounting platforms and four infrared sensitive planes, and the four driving motor mounting platforms and the four infrared sensitive planes are arranged in a staggered mode. The high-accuracy dual-axis optical fiber gyroscope micro measurement device is small in mass and compactin structure, gives consideration to requirements for both mass and the mass center by reasonable layout of a position of each component of the integral device and ensures the minimum integral rotational inertia of the product.

Description

technical field [0001] The invention belongs to the field of space satellite micro-measurement equipment, and more specifically relates to a high-precision dual-axis fiber optic gyro micro-measurement device. Background technique [0002] With the rapid development of inertial measurement technology, the application of fiber optic gyroscope in the field of inertial measurement is becoming more and more mature, and miniaturization and miniaturization of measurement devices has become inevitable.
