Abstract

There is herein described a device useful to store a frame of low-intensity optical information over a wide spectral range or useful as a real-time light valve in visible to infrared conveter application. The device basically includes either a storage mode liquid crystal or a dynamic scattering or a field-effect liquid crystal, and a semiconductor diode array substrate wherein an insulating film with an array of conducting windows separates the liquid crystal from an active region in the substrate. A separate diffused junction is disposed in the active region adjacent each of the windows, the latter being adapted to both reflect incident light energy and conduct electrical current.
