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
