Discrimination between speckle images using diffusers modulated by some deformed apertures: simulation
Hamed, Abdallah;
Abstract
We investigate new numerical speckle images using a 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 used
the concept of Fourier transform. We computed the point spread functions (PSF) for the modulated circular, elliptical, and cardiac apertures.
