四频差动激光陀螺的研制与进展

四频差动激光陀螺原理先进,特别是在消除低转速时的闭锁效应方面具有独特的优点,因而具有强大的生命力,现已成为美国两个主要陀螺公司之一的利顿公司的第二代激光陀螺。在国内,四频差动激光陀螺的研制已经成功地走过了原理样机和实验室样机两个阶段,目前正在进行工程化攻关。本文从四频差动激光陀螺的原理和特点出发,简要介绍近年来国内外四频差动激光陀螺的研制动态,对四频差动陀螺的各种新方案和新进展进行了分析

The study and progress in four-mode differential ring laser gyro

The Four mode Differential Ring Laser Gyro (FDRLG) has advanced principles and a special advantage of eliminating the lockin effect which occurs at low rotation rates.As a result of its great vitality,FDRLG has become the coming generation laser gyroscope of Litton System Inc.,one of the main companies of gyroscope in USA.The study and manufacture of FDRLG,conforming to the conditions of our country,have successfully gone through two stages of principle and experimental specimen machines,and now have got into engineering stage.The practical FDRLG will be made by us in the near future.Proceed from the principle and characteristic of FDRLG,this paper introduces the study and progress of FDRLG at home and abroad.Many of new schemes and new advances of FDRLG are especially analysed.
