In PIS (Programmable Imaging System) testing, where the spatial frequency of the spatial light modulator is inconsistent with that of the image device, Morie Fringes are generated. To further develop the PIS instrument, it has to abate the effects of Morie Fringes on the image quality. In this paper, we implemented an approach using spatial filtering in the Fourier Spectrum. Since “ringing” phenomenon is caused by the “notch filter”, to prevent it, a multiple-point Gauss Filter based on the “notch filter” has been designed. The tests have indicated that this approach can efficiently reduce the effects of the issue on the image quality, and the images reconstructed are clear and almost free from “ringing”,thus reaching the requirements for the instrument.
