Patent number: 9933753Abstract: A method of enlarging an observation window from which the reconstruction from a Computer Generated Hologram (CGH) may be viewed, including reproducing a CGH, and shifting a location of an exit pupil or observation window of an optical system reproducing the CGH. A method of increasing a viewing angle from which the reconstruction from a Computer Generated Hologram (CGH) may be seen, including producing a plurality of instances 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.Type: GrantFiled: July 30, 2013Date of Patent: April 3, 2018Assignee: Real View Imaging Ltd.Inventors: Shaul Alexander Gelman, Shlomo Alon-Braitbart, Yuval Yehuda Yoreh, Carmel Rotschild

Patent number: 9709953Abstract: 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 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 image including computing a first modulation for a first holographic image, and computing a second modulation for a second holographic image of a same 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.Type: GrantFiled: July 30, 2013Date of Patent: July 18, 2017Assignee: Real View Imaging Ltd.Inventors: Shlomo Alon-Braitbart, Shaul Alexander Gelman, Carmel Rotschild

Publication number: 20170090420Abstract: A method for displaying a hologram to a variable direction including using circuitry to determine a direction from a holographic projector to a viewer for projecting a hologram to a viewer, and projecting a hologram in the determined direction, in which the projecting the hologram includes reflecting from a same mirror as the determining the direction of the viewer, and the circuitry controls the projecting the hologram to a direction corrected for a difference in direction between a projecting unit and a tracking unit relative to the mirror. Related apparatus and methods are also described.Type: ApplicationFiled: December 8, 2016Publication date: March 30, 2017Applicant: Real View Imaging Ltd.Inventors: Carmel ROTSCHILD, Aviad KAUFMAN
