Abstract: A method of enlarging an observation window (330) from which the reconstruction (35,305) from a Computer Generated Hologram (CGH) may be viewed, including reproducing a CGH, and shifting a location of an exit pupil or observation window (330a, 330b) of an optical system reproducing the CGH (10,15,20,25). A method of increasing a viewing angle from which the reconstruction (35,305,705) from a Computer Generated Hologram (CGH) may be seen, including producing a plurality of instances (714,715,716) of a CGH, projecting each one of the instances in a different direction so that a first exit pupil of a first instance is close to a second exit pupil of a second instance. An optical system including a plurality of exit pupils associated with a plurality of optical components, further including a light deflector for jittering a location of a first exit pupil so as to increase an overlap of the first exit pupil with a second exit pupil. Related apparatus and methods are also described.

Abstract: A method for despeckling the image reproduced by a Computer Generated Hologram (CGH) including reproducing a CGH, and jittering a location of an exit pupil (33,250) of an optical system through which the CGH is imaged, relative to an observer's input pupil (31,255), so as to shift at least some speckles (32,260) out of the exit pupil. A method for despeckling a Computer Generated Holographic movie including computing a first modulation for a first holographic image in a holographic movie, and computing a second modulation for 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.
