Abstract

A proposed method for spatially modulating a laser beam involves changing the refractive index uniformly over a variable area. The width of the area pattern is determined by the applied signal to be processed. The refractive index change would be "written" by optical means on the surface of the material. This paper describes the method mathematically and points out key factors that influence recording quality.
