由于环形激光陀螺(RLG)在航空航天和其他领域中的应用越来越广,其生产量将进一步增长,各公司针对不同性能范围和不同应用场合开发出了一些新的激光陀螺设计方案.这些研究主要体现在以下三方面.磁镜偏频小型激光陀螺所谓“磁镜”方案,即利用横向克尔效应,使照在磁镜上的一束激光相位超前,其反向光束相位滞后,从而造成相位偏移.这是一种依靠纯粹光学代替抖动机电机构的偏频方案,可使激光陀螺真正成为无活动件的全固态装置,
As the ring laser gyro (RLG) in the aerospace and other fields more and more widely used, its production will further increase, companies for different performance ranges and different applications have developed a number of new laser gyro design. These The research is mainly reflected in the following three aspects: Magnetic mirror bias small laser gyroscope The so-called “magnetic mirror” scheme, that is, the use of horizontal Kerr effect, so that a mirror in the magnetic phase of the laser phase ahead of its reverse beam phase lag, which Resulting in a phase shift.This is a purely optical instead of jitter electromechanical mechanism of the partial frequency scheme, the laser gyro can truly become a solid-state device without moving parts,
