New Method of Studying the Statistical Properties of Phase Difference of the Speckle Fields

WANG Qian-kai(College of Physics and Electrical Information,Anhui Normal University,Wuhu,Anhui 241000,China)  
A new theoretical method with generality is proposed to study the free statistical properties of the phase difference of the speckle fields.The general expression of the standard deviation of phase difference of the speckle fields is derived according to the relations between the phase difference and the complex speckle amplitude.The statistical properties of phase difference of the Gaussian speckle fields have been investigated in the diffraction fields with this new theoretical method.
