摘要： A membrane light modulator (18) comprising a charge transfer plate (30), and having a multiplicity of conductors (35) extending from the rear surface (52) to the front surface (19) of the plate (30). The conductors (35) are supported in an insulating matrix (37). The front side (19) of the transfer plate (30) has a plurality of potential wells (32) defined by insulating walls (15), each potential well (32) constituting a pixel. A plurality of conductors (35) is provided for each pixel. A deformable reflecting membrane (34, 36) comprising a metal layer (36) spans the potential wells (32). An electric potential is provided on the metal layer (36), and a source of electrons (17) is provided for impacting the rear surface (52) of the charge transfer plate (30).
