Abstract

We investigate new numerical speckle images using diffuser provided with some classes of amplitude apertures. The 1st class is based on circular aperture modulation, the 2nd class assumes modulated elliptical apertures, while the 3rd is devoted to a cardiac, and comet deformed apertures. We have reconstructed the images of all apertures and using the concept of Fourier transform. We computed the point spread functions (PSF) for the modulated circular, elliptical, and the cardiac apertures.
