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...
