Abstract:
1. A biocular projection system configured to project digital images fed to a transmissive micro-LCD display at resolutions as high as 1920×1080 pixels, the biocular projection system configured to be used with both a micro-LCD display and a biocular lens, the biocular projection system comprising: a micro-resolution screen comprising a micro-diffusion surface applied to a single planar transparent substrate that has a smooth surface on a side opposite the micro-diffusion surface, the micro-diffusion surface comprising surface features configured to diffuse the light passing therethrough at greater than a 60-degree diffusion angle; and a relay lens assembly comprising a plurality of lenses configured to transfer digital images from a transmissive micro-LCD display to the micro-resolution screen surface at a magnification ratio corresponding to the desired field of view of a corresponding biocular lens with which the biocular projection system is intended to be used, whereby when the biocular projection system is used with both a micro-LCD display and a biocular lens, the biocular projection system can be used to effectively project such digital images with minimal loss of resolution quality even where the viewer is in very close proximity to the micro-LCD display and a wide viewing angle is desired without compromising illumination when used with varying binocular lenses.
