静电陀螺仪光电信号器

The Photoelectric Signal Device of Electrostatically Suspended Gyroscope

空心转子静电陀螺仪通常采用光电信号器进行动量矩位置信息的读取。光电传感器的分辨率、零位噪声和光轴稳定性对陀螺漂移精度和长期工作稳定性有直接影响。本文对静电陀螺仪光电信号器工程实践中的有关理论和技术问题作了较为详细的论述。

Electrostatically suspended gyroscope(ESG),using a hollow sphere as its rotor,usually picks its position information of the polar axis with a photoelectric signal device.The resolution,null noise and stability of photo-axis affect directly the drift accuracy and long running stability of the gyro.This paper discusses the relative theory and some technic problems on engineering practice of the ESG photoelectric signal device.
