摘要
空芯光子晶体光纤谐振式光学陀螺在保有谐振式光纤陀螺高精度、小型化优势的同时,通过采用空芯光子晶体光纤取代传统保偏光纤制作谐振环,可以从机理上抑制目前谐振式光纤陀螺所面临的偏振噪声、克尔噪声、背向散射噪声等问题,同时极大地提高了陀螺系统的温度稳定性和抗辐照能力。本文介绍了空芯光子晶体光纤谐振式光学陀螺的研究背景和意义,结合国内外研究机构的研究成果,详细介绍了该技术领域的发展现状,分析并指出当前该技术领域研究的核心问题,为该新型光学陀螺技术的进一步研究提供指导。
The hollow-core photonic crystal fiber resonant optical gyro(HC-RFOG)inheriting these advantage, high sensitivity and little size, of traditional resonant optical gyro, is supposed to restrain polarization noise, Kerr noise and backscattering noise from foundational mechanism, and is equipped with excellent thermal stability and radiation resistant ability. In this paper, the great significance of the HC-RFOG is announced, the development and technological advances of this novel optical gyro are reviewed, and the key points of current technology researches of HC-RFOG are discussed.
