一、总体参数的确定及总体方案的选择棱镜透镜干涉仪(又称泰曼-格林干涉仪)是棱镜干涉仪和透镜干涉仪的总称,是一种高精度、多功能的光学测试仪器。棱镜干涉仪用于检测具有平面性质的光学零件或光学系统的质量,如平板玻璃、各种棱镜以及望远系统等。透镜干涉仪主要用于测定望远物镜、照相物镜的波象差。棱镜透镜干涉仪采用的是分振幅双光束相干光路,其中测试光路的标准平面波经被检测的光学零件或光学系统后变成了由被检测件质量所决定的变形波面,该波面与参考光路的标准平面波汇合而产生干涉图形,根据干涉图形
First, determine the overall parameters and the overall program of choice Prism lens interferometer (also known as the Terman - Green interferometer) is a prism interferometer and lens interferometer in general, is a high-precision, multi-functional optical test equipment. Prism interferometers are used to inspect the quality of optical components or optical systems with planar properties such as flat glass, various prisms, and telescopic systems. Lens interferometer is mainly used for measuring telescopes, photographic lens aberration. Prism lens interferometer uses sub-amplitude dual-beam coherent optical path, where the test optical path of the standard plane wave is detected by the optical components or optical system into a test piece by the quality of the deformation wavefront, the wavefront and the reference light path Standard Plane waves combine to produce interference patterns, according to the interference pattern
