Transparent holographic display with dynamic image control

摘要

Generally, this disclosure provides systems and methods for generating three dimensional holographic images on a transparent display screen with dynamic image control. The system may include a transparent display screen that includes an array of pixels; a driver circuit configured to control each of the pixels in the array of pixels such that the transparent display screen displays an interference fringe pattern, the interference fringe pattern associated with a hologram; and a coherent light source configured to illuminate the transparent display screen with coherent light, wherein transformation of the coherent light by the interference fringe pattern generates a three dimensional holographic image.

主权项

1. A system for generating a holographic image, said system comprising:
a transparent display screen comprising an array of pixels; an interference pattern reconstruction module to generate an interference fringe pattern from an approximation of said interference fringe pattern stored in a memory of the system, the approximation comprising an estimate of a direction and a period of segments of stripes within regions of the interference fringe pattern, the interference fringe pattern associated with a hologram; a driver circuit configured to control each of said pixels in said array of pixels such that said transparent display screen displays the interference fringe pattern; and a coherent light source configured to illuminate said transparent display screen with coherent light, wherein transformation of said coherent light by said interference fringe pattern generates a three dimensional holographic image.
