Abstract
A holographic display and a method, performed by the holographic display, of forming a holographic image are disclosed. The holographic display includes an electrically addressable spatial light modulator (EASLM); a diffractive optical element (DOE) mask array arranged on the EASLM; and a controller configured to operate the holographic display to form a hologram image, wherein the controller is further configured to address the EASLM to backlight the DOE mask array required to form a set of hologram image voxels by turning on a corresponding EASLM pixel.
Claims13
A holographic display comprising:
- an electrically addressable spatial light modulator (EASLM);
- a diffractive optical element (DOE) mask array arranged on the EASLM;
- and
- a controller configured to operate the holographic display to form a hologram image,
- wherein the controller is further configured to address the EASLM to backlight a DOE mask of the DOE mask array required to form a hologram image voxel by turning on a corresponding EASLM pixel, and
- wherein the DOE mask array comprises at least one DOE mask having a diverging or converging lens and a DOE mask having a transparent area, and the holographic display is configured to switch between three-dimensional (3D) and two-dimensional (2D) modes by backlighting the at least one divergent or convergent lens of the DOE mask array or the transparent area of the DOE mask array, respectively.
