Abstract

A method for despeckling a Computer Generated Hologram (CGH) including producing a CGH, and jittering a location of an exit pupil of an optical system through which the CGH is imaged, relative to an observer's input pupil, so as to shift at least some speckles out of the exit pupil. A method for despeckling a Computer Generated Holographic movie including computing a first modulation of a first holographic image in a holographic movie, and computing a second modulation of a second holographic image using an initial phase distribution used for calculating the first holographic image as an initial phase distribution used for calculating the second modulation. Related apparatus and methods are also described.
