A proximity-focused microchannel spatial light modulator that consists of a photocathode, a microchannel plate, a mesh electrode, and an oblique-out LiNbO3 plate [(ZX1) 55°)] is investigated. This paper describes the design consideration and the fabrication techniques. A prototype device optically addressed with ultraviolet light from a mercury lamp has been built and the two- dimensional He- Ne laser light-intensity modulation experiments were performed.
