Embodiment Construction

[0029] One aspect of the present invention is the use of a TDG modulator comprising a set of electrodes located at a functional distance from the gel, membrane or polymer etc. such that when an appropriate voltage is applied to the electrodes the diffraction grid formed on the surface. One of the features of such TDG modulators is that several sets of independent electrodes can be combined at a functional distance from the gel or membrane, thus respectively providing light incident on different parts of the surface of the gel or membrane located on each electrode set. individual diffraction. Thus, according to an example of an embodiment of the present invention, splitting of an incident beam such as a laser and providing polarization and then directing the polarized beam towards the corresponding part of the gel or film surface of the TDG component makes it possible to modulate the image for the left and right eyes separately. Optics arranged eg before and / or after the modul...

Abstract

A modulator and an apparatus comprising the modulator comprising a Tunable Diffraction Grating (TDG) component is arranged with a plurality of individual modulator sections, wherein a prism with appropriate chromatic and polarization filters provides at least two independent overlaid two dimensional images providing stereographic displays for three-dimensional images.

Description

technical field [0001] The present invention relates to display systems, and in particular to three-dimensional image generating line scan projection systems comprising modulators with tunable diffraction grating (TDG) elements and specially designed prisms which provide different colors and / or Or splitting, recombination or both splitting / recombining of polarization states. Background technique [0002] In recent years, image projectors, and particularly digital projectors, have found increasing popularity as tools for presenting various information to viewers. Typically, these projectors are used to project computer-generated images onto a viewing surface. Image projectors allow users to easily present high-quality images with a wide range of sizes to audiences. As a result, these projectors are now often found as permanent fixtures in conference rooms and other meeting spaces. [0003] Images projected by typical image projectors generally appear flat and two-dimension...
