GENERAL THEORY ON PERFORMING OPTICAL TRANSFOR-MATION USING AMPLITUDE-PHASE MASKS
用振幅-相位型全息透镜实现光学变换的一般理论

In this paper the previous theory on performing a given linear transform using the pure phase mask system1,2] has been generalized to the more general case in which an optical system is composed of amplitude-phase masks. A set of equations which is necessarily satisfied by the amplitude and phase distributions of the masks is given. It is easy to solve them by means of the iteration computing method.
