HOLOGRAPHIC IMAGING OPTICAL DEVICE

摘要

In relation to a field of creating and processing a digital image, a compact portable device for generation and observation of dynamic and static holograms is provided. A system including a holographic display may be based on reconstruction and transmission of a wavefront encoded with a spatial light modulator while preserving information about a wave amplitude and a phase. Due to such features of the holographic process, an optical device may restore a wavefront similar to a wavefront coming from real objects.

1. An optical device that generates and displays a holographic dynamic and static 3-dimensional (3D) image, the optical device comprising:
a laser source of coherent radiation; a light guiding plate; a holographic optical element fixed to a surface of the light guiding plate; a spatial light modulator to generate a digital hologram; and at least one electronic unit comprising an interface unit and a control circuit for the spatial light modulator, wherein the holographic optical element is arranged along a radiation path from the laser source such that the spatial light modulator is disposed on the light guiding plate after the holographic optical element redirects the radiation into the light guiding plate and before the holographic optical element redirects the radiation outward from the light guiding plate.
