| Abstract: | The authors established a ideal diffuser model,and computed the correlation between two adjacent speckle patters with a lateral displacement of the diffuser.The theoretical analyses shows that a decorrelation effect appears when the diffuser has a lateral displasement.The conclusion is useful in experimental application. |
