摘要
自20世纪70年代以来,伴随着光通信领域中光纤、光源和相位调制器等光学器件的逐渐应用和走向成熟,具有独特优势的基于Sagnac效应的干涉式光纤陀螺(IFOG)技术得到了迅速发展。40多年来,该技术从实验室走向了陆海空天等各个领域。回顾了IFOG技术的发展过程。首先,介绍了自Sagnac效应发现至实用化期间IFOG技术的探索历程。然后,阐述了IFOG经典的最小互易光学结构与信号处理方案。接着,梳理了IFOG技术在高精度、小型化和环境适应性等方面的研究现状。最后,分析了该技术发展、应用的趋势和方向。
Since the 1970s,the interferometric fiber-optic gyroscope(IFOG)technology based on the Sagnac effect,which boasts unique advantages,has developed rapidly with the increasing application and maturity of optical devices such as optical fibers,light sources,and phase modulators in optical communication.Over the past 40 years,this technology has moved from the laboratory to various practical fields such as land,sea,air,and space.This paper reviews the recent development of the IFOG technology.Firstly,the exploration process of this technology from the birth of the Sagnac effect to its practical applications is introduced.Secondly,the classical minimum reciprocity configuration of IFOGs and the signal processing scheme are described.Then,the research status of this technology in high precision,miniaturization,and application environment adaptability is summarized.Finally,the development and application trends of this technology are analyzed.
