Blazed Surface Relief Holographic Optical Elements.
Abstract
A method of making a blazed surface relief holographic element is disclosed using controlled orientation of exposing wavelengths on a photo resist surface to a substrate. A blazed surface serves a grating which reinforces diffraction by refraction of the blazed surface. This increases theorically obtainable diffraction effeciency to greater than 90%. Alternate methods of surface formation include holographic exposure and computer mask generation. Different blaze angles can be obtained depending on the angle of incidence. (Author)
