摘要
A method is derived for obtaining more-intense multiple images. The method is based upon spatial-frequency filtering with auxiliary sampling. This method is derived and realized physically. The spatial filter, composed of periodically spaced holes in a black screen, is placed in the Fourier plane of the two-dimensional object. Filters were used that included auxiliary lattices of the same period, translated from each other by arbitrary vectors; consequently the multiple images that are formed in the image plane are superimposed and reinforce each other.
