Abstract

In a white-light optical processing system, if the filter apertures vibrate randomly around the rainbow diffraction spectra at Fourier plane, the amplitude grain noise of the grating encoded film in the output plane can be suppressed considerably and the output SNR is improved. Experimental results are given in this paper.
