A device for providing a reverse pass-through view of a user of a headset display to an onlooker includes an eyepiece comprising an optical surface configured to provide an image to a user on a first side of the optical surface. The device also includes a first camera configured to collect an image of a portion of a face of the user reflected from the optical surface in a first field of view, a display adjacent to the optical surface and configured to project forward an image of the face of the user, and a screen configured to receive light from the display and provide the image of the face of the user to an onlooker.

The invention discloses a three-dimensional display method for large field of view and small viewing-zone interval. A display screen constructed by sub-screens with adjacent ones emitting lights of different exclusive optical characteristics is employed, and sequentially-switching aperture-arrays are placed close to a pupil of the viewer. M apertures of an aperture array correspond to the M sub-screens by a one-to-one manner in turn, to make the transmittance of each aperture to the light from the corresponding sub-screen be greater than that to the lights from the adjacent non-corresponding sub-screens by a ratio larger than 9. The corresponding apertures of a sub-screen in different aperture-arrays are arranged with an interval not larger than the diameter of the pupil. At a time-point, only one aperture-array gets open, and all aperture-arrays get open sequentially at different time-points of a time-period. At each time-point, each sub-screen presents optical information to the corresponding turned-on aperture synchronously. When the time-period is small enough, a three-dimensional display with large field of view and small viewing-zone interval gets implemented.

The present invention provides a device comprising circuitry configured to obtain a plurality of initial two-dimensional, 2D, images which together represent an initial three-dimensional, 3D, image, wherein each initial 2D image is associated with one of a plurality of focal planes. The device is further configured to generate one or more blurred versions of each of the initial 2D images on one or more of the focal planes other than its associated focal plane; generate a high passed version of each of the initial 2D images on its associated focal plane; and generate a plurality of final 2D images by generating for each focal plane a final 2D image based on the high passed version of the initial 2D image associated with that focal plane and one or more blurred versions generated on that focal plane from one or more of the other initial 2D images.

A holographic projection system is disclosed for cost-effectively generating “real image” holographic images. In at least one embodiment, the system provides an at least one primary image source configured for projecting a primary image via an at least one light ray. A computing device is in communication with the at least one primary image source and configured for providing the primary image to be subsequently projected by the at least one primary image source.
