The book is devoted mainly in discussing the operator algebra in the computation of the Point Spread Function for some modulated apertures using Gaussian Laser illumination. Secondly, Segmentation and improvement of reconstructed images from Fourier holograms is obtained using the mammographic images. Finally, Holographic imaging using Scanning Fresnel holograms provided with modulated linear and quadratic apertures is discussed giving better reconstructed images compared with uniform circular aperture manipulation.
