In computer generated holography, the object need not exist and it is enough if the object is known in mathematical form. The idea was first proposed by Adolf Lohmann[18] and later many others[19-21] have contributed significantly to computer generated hologram. The computer-generated holograms are binary as they consist of many transparent dots on an opaque background. The binary character of computer holograms facilitate their reconstruction in real sense.
