Liquid crystal light valve goggles for eye protection.

摘要

An eye protection device (10) comprising a liquid crystal light valve (20) far providing an image of a scene. The light valve (20) images the field of view under observation in a spectral range which matches the human eye. It will automatically reject a laser threat by simply absorbing the energy therefrom in the photoconductive layer thereof. Thus, the invention (10) provides a broad spectrum, zero response time, angle and polarization independent, sensitive eye protection device having a fast recovery time, high extinction coefficient and a high damage threshold. Hence, the invention is expected to be of significant utility to personnel operating in hostile environments. <IMAGE>
