Abstract:
A membrane light modulator comprising a charge transfer plate, and having a multiplicity of conductors extending from the rear surface to the front surface of the plate. The conductors are supported in an insulating matrix. The front side of the transfer plate has a plurality of potential wells defined by insulating walls, each potential well constituting a pixel. A plurality of conductors is provided for each pixel. A deformable reflecting membrane comprising a metal layer spans the potential wells. An electric potential is provided on the metal layer, and a source of electrons is provided for impacting the rear surface of the charge transfer plate.
