Paper Abstract

Computer-generated holograms have many applications in diverse areas such as storage, processing and display of information, creation of difficult to obtain reference wavefronts, as logic-switching elements in optical computing etc. A majority of digital holograms evolved over the past two decades have been specifically designed to record information in the Fourier plane. One particularly important class of such holograms is based on the 'detour phase' principle developed by Lohmann and his co-workers [1]. These are mainly binary transimittance Fourier transform holograms with the most notable ones being the Lohmann, Lee and Burckhardt formulations [1], as also the double phase hologram (DPH) devised by Hsueh and Sawchuk [2] etc. Our interest in this paer will be confined to evaluating the image fidelity of these four holograms, and some of their variations as well.
