剪切干涉灵敏度和剪切图的全处理方法的研究
Sensitivity of lateral shear interference and full-processing of lateral shear interferograms
波面 变剪切 平均灵敏度 剪切图 全处理 wavefront variable shear average sensitivity shear interferograms Full-processing
摘要
本文对剪切干涉灵敏度进行定量讨论,首次提出平均灵敏度数学模型,它圆满地解释了剪切干涉特性.通过讨论得出一个重要结论,要准确求出待测波面,必须用变剪切干涉仪,使用不同的切量对同一波面进行测量.然后采用一种新方法——剪切干涉图全处理的方法,求出待测波面.
Abstract
The sensitivity of lateral shear interference is quantitatively discussed and the model of average sensitivity is presented, it can explain the theory of lateral shear interference completely. The important result has been obtained that if a tested wave-front is to be reconstructed correctly, we had better use a variable shear interferometer to test it, that is, using more than one shear to test the same wavefront. Then, the tested wavefront can be solved with a new method-Fullprocessing of Lateral Shear Interferograms.
