【摘要】 一张剪切干涉图不足以描述一个波面.要重构一个任意形状的波面,必须用两张正交方向剪切的干涉图.本文研究了两种类型的二维横向剪切干涉仪:正交剪切棱镜型和网格光栅型.论述了用干涉图数据来重构波面的方法,并用这种方法处理了我们实验中所获得的干涉图.更多还原

【Abstract】 A single shearing interferogram is not sufficient to describe a wavefront. Two interferograms sheared in orthogonal directions must be used to reconstruct the wavefront of any arbitrary shape. Two types of two dimensional lateral shearing interferometers have been studied: orthogonal shearing prism and crossed grating. A method is described that uses data obtained from the interferograms to reconstruct the wavefront. It was used in processing the interferograms obtained in our experiment.更多还原
