Abstract

Provided is an 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.
