The structure and design of diffractive optical diffusers for display applications is discussed and a new technique for designing complex relief structures with new, improved diffuser behaviour is described. Such diffusers can be fabricated by laser beam writing techniques. A specific example is given of a diffractive diffuser for improving the subjective quality of color CRT data displays by acting as a low-pass spatial-frequency filter to reduce the noise generated by the matrix dot structure.
