为了消除环境振动的影响,本文将研究空间移相干涉术中的同步移相干涉方法。这种方法可以在同一时间内得到多幅干涉图,从而提高测量的精度。目前国内外同步移相干涉仪器中泰曼型的居多,所以论文重点研究了斐索型同步移相干涉仪,包括如何将参考光和测试光进行分离,从而引入偏振移相;如何设计基于偏振移相的斐索型同步移相结构;设计满足设计要求的波片与光栅,选择合适的光源及成像器件;使用琼斯矩阵进行原理性计算;搭建实验平台,采集实验图像,分析实验数据以及实验误差。

Title Research on the test technology of Fizeau synchronous phase shifting interferometry based on polarization phase shift。
Abstract With the development of science and technology,the optical elements in the forefront of science,astronomy,aerospace,energy and other fields have been widely used, and the measurement accuracy of the optical elements are in increasingly high requirements。 Phase shifting interferometry(PSI) is a conventional high measurement accuracy, but in the conventional phase shifting schemes,environment vibration still be a great error in measurement system。
In order to eliminate the impact of environmental vibration, this article will examine the spatial phase shifting interferometry in synchronous phase shifting interferometry。 This method can obtain multiple interference patterns at the same time, in order to improve the measurement accuracy。 At home and abroad,there are too many Twyman synchronous phase shifting interferometer, so this paper focuses on the Fizeau synchronous phase shifting interferometer, including how to separate the reference light and the test light, thereby introducing polarization phase shift; how to design based on polarization Fizeau-type phase synchronous phase shifting structure; designed to meet the design requirements of the wave plate and grating, select the appropriate light source and the imaging device; the principle of using Jones matrix calculation; experimental platform, image capture experiments, analysis of experimental data and experimental error。
Keywords: synchronous phase shift;Fizeau;vibration-resistance;Jones matrix。
