Provided are diffused but transmissive optical image projection screens and methods of their manufacture, including screens comprising acetal polymers such as polyoxymethylene. Such screens may be used in various applications, including but not limited electronic image display and control system comprising in various embodiments a microdisplay video projector that projects a high quality color image from a non-CRT image source onto a diffused but transmissive optical projection screen that is optically coupled with and viewable through a biocular adapted to this purpose. Systems are disclosed that are adapted to be mechanically coupled with a user to prevent relative movement between the biocular and the user, for instance in tactical applications. Closed-loop control electronics are provided for automatically controlling the brightness and chromaticity of the image.
A diffused but transmissive optical projection screen adapted for use with an electronic image display system that projects an image onto a first proximate side of the diffused but transmissive optical projection screen such that the image is viewable on a second distal side of the diffused but transmissive optical projection screen, the diffused but transmissive optical projection screen comprising a sheet of diffusive material consisting essentially of Acetal.
A diffused but transmissive light screen adapted to diffuse light projected onto a first proximate side of the diffused but transmissive light screen such that the light is emitted in a diffused pattern on a second distal side of the diffused but transmissive light screen, wherein the diffused but transmissive light screen comprises:
A method of constructing a diffused but transmissive optical projection screen adapted for use with an electronic image display system that projects an image onto a first proximate side of the diffused but transmissive optical projection screen such that the image is viewable on a second distal side of the diffused but transmissive optical projection screen, comprising the steps of:
