Paper Abstract

The first method for designing the amplitude hologram was proposed by Lohmann employed properties of irregular amplitude diffraction gratings, that is, every slit of the diffraction grating is smashed into pieces where every piece has a position (P) and a wide (W), the control of these parameters enable the detour and the change of a wave front to one that we want. Though it has a few inconveniences, which are show in this work. One analysis of the diffraction patterns with various geometric apertures differences to the Lohmann type is showed too. These coding methods are apply to Fourier and Fresnel holograms type. We shown the effect of the surround that each one causes in the diffraction pattern in order to determine the conditions for the better visualization of the reconstructed image.
