摘要：
A method of reconstruction of the object image from a recorded speckle pattern of the scattered coherent radiation field has been developed and experimentally verified. In order to restore information about the phase of the diffraction field, which is lost during the recording of the speckle pattern, it is suggested to take the phase difference between adjacent speckles equal to pi. The proposed method is applicable to objects for which the average intensity distribution is described by an even function of the coordinates. (C) 2004 MAIK "Nauka / Interperiodica".
