Paper Abstract

The statistical properties and correlation properties(1,2J of speckle patterns have been extensively studied and widely used to measure the parameters of rough-surface[3,41 Asakura[51,Vorbuger and Teague (6:J and Ruff ing(71 reviewed optical measurement techniques of surface topography, including the two main groups of speckle methoda using average contrast and the degree of correlation of speckle patterns, respectively as roughness-dependent parameters, These methods are all based on the intensity properties of speckle patterns,this makes the theoretical analysis and experiment complicate and timeconsuming By comparing the holography and speckle correlation technique, we propose a technique---holographic speckle correlation technique---based on the correlation of the complex amplitudes of speckle fields and use it to measure the roughness of diffuser.
