A SCHEME OF HOLOGRAPHIC METHOD FOR OBTAINING A SINGLE MASK FOR REALIZATION OF GENERALIZED TRANSFORMS
用全息术获得单片广义变换掩膜板的方案

A scheme of multi-exposure holographic method for obtaining a single mask for realization of a kind of unitary transforms is suggested. The formula of signal-to-noise ratio of the transform due to masks of this sort is deduced from a statistical point of view.
