Abstract

A binary phase grating that has a 2D periodic phase structure is useful to generate the directional diffuser. Recent analysis and computation for the periodically phase distributed plate will give the most optimized characteristics of the diffuser. This binary phase grating is successfully obtained, large enough, by a planar fabrication technique such as photolithography. Typical application of the phase grating for a clear and high efficiency focusing screen of the viewer is presented.
