Abstract

A method of displaying a Computer Generated Holographic (CGH) image by a display, including setting pixel values of a Spatial Light Modulator (SLM) included in a Head Mounted Display (HMD), producing a interference based holographic image at a first location by projecting coherent light onto the SLM, and re-imaging the holographic image from the first location to form a holographic image in front of an eye of a viewer wearing the HMD. Related apparatus and methods are also described.

RELATED APPLICATIONS

[0001] This application claims priority of U.S. Provisional Patent Application No. 62 / 410,494 filed on 20 Oct. 2016, of U.S. Provisional Patent Application No. 62 / 298,070 filed on 22 Feb. 2016 and of U.S. Provisional Patent Application No. 62 / 298,036 filed on 22 Feb. 2016, the contents of which are incorporated herein by reference in their entirety.FIELD AND BACKGROUND OF THE INVENTION

[0002] The present invention, in some embodiments thereof, relates to a display for projecting a Computer Generated Hologram (CGH) image to a viewer via an optical element close to the viewer's eye or eyes, such that the CGH image appears to the viewer as beyond the optical element, and more specifically, in some embodiments the optical element may be at least semi-transparent, so that the viewer may see the real world simultaneously with seeing the CGH image.

[0003] The present invention, in some embodiments thereof, relates to a Head Mounted Display (HMD), and to methods of using one ...
