Abstract: The basic rule of using regulated path length holography to measure three-dimensional displacement is discussed in this paper. The modified formula of the position of measured points on the images of the curve surface object is derived by using geometric optics.Holographic images have been processed with the help of microdensitometer.In the end,measured results have been given.
