摘要：

Design of a simple diffuser, in which the absolute value of the phase difference between the diffuser's adjacent samples is constant, is considered. A condition is imposed in the design so that the diffuser is suitable for use with the iterative method based on the iterative Fourier transform algorithm for calculating a two-dimensional complex amplitude function that possesses a bandlimited and smooth spectrum. A method for effectively designing this diffuser is proposed, and its application in the field of digital holography is presented. (C) 2002 Society of Photo-Optical Instrumentation Engineers.
