【摘要】

：

谐振式光纤陀螺(RFOG)是基于Sagnac效应产生的顺时针光路与逆时针光路的谐振频率差来测量旋转角速率的光学传感器.由于Sagnac效应极为微弱,RFOG常采用信号调制解调技术提高检测精度.首先介绍了基于正弦相位调制解调的RFOG的基本原理及衡量其性能的主要指标,详细推导了基于正弦相位调制解调的RFOG系统受散粒噪声制约的理论角度随机游走(ARW)的表达式,分析了调制参数包括调制频率和调制系数对理论ARW的影响.研究表明,在给定的激光功率及光纤环形谐振腔条件下,存在一组最佳的调制参数和解调相位,用于实现

大陡度透镜表面膜层折射率均匀性分析

集成电路与光刻机系统中通常会设计并使用很多小曲率半径的大陡度透镜,以实现大数值孔径,这对镀制于其表面的紫外薄膜的性能提出了很高的要求.本文分析了行星夹具转动过程中大陡度凸透镜从中心到边缘位置的薄膜沉积角度的变化规律,研究了 MgF2膜层的折射率随沉积角度的变化规律,明确了大陡度凸透镜从中心到边缘位置的膜层折射率不均匀性对深紫外增透膜的影响.针对小曲率半径大陡度凸透镜表面的膜层沉积特性,通过升高基底温度提高了折射率分布的均匀性,为大陡度透镜膜层折射率不均匀性修正提供了理论和实验依据.
