把光纤陀螺用于空间系统正引起人们极大关注,这是因为近年来麦道公司研制的由模块组成的光纤陀螺取得了重大进展的结果。这种光纤陀螺不仅能抗恶劣环境的荡动、冲击和温度影响;而且可靠性高、复杂程度低、生产周期短。目前,正在研制速率控制器件,今后几年内可望用于姿态控制系统。为了给光纤陀螺的应用提供一种评审标准,本文对模拟式、数字式光纤陀螺与激光陀螺的参数特征和生产工艺进行了对比介绍。
The use of fiber optic gyros for space systems is attracting a great deal of attention because of the significant advances made by modular fiber optic gyroscopes developed by McDonnell Douglas in recent years. This fiber optic gyroscope can not only withstand the harsh environment of the swing, impact and temperature effects; and high reliability, low complexity, short production cycle. Currently, rate control devices are being developed and are expected to be used in attitude control systems in the next few years. In order to provide an evaluation standard for the application of fiber optic gyroscopes, this paper introduces the comparison of the parametric characteristics and the manufacturing process of analog, digital fiber optic gyros and laser gyros.
