Some Simple Design Considerations for Binary Optical Holographic Elements
Abstract
It has been shown previously that an optical analysis based on a ray trace can prove to be beneficial in the design of binary type phase holograms, because the optical path of each ray must be taken into account. Binary elements converted directly from thick, classically designs to Fresnel/binary equivalents, without a redesign will probably have reduced performance. Furthermore, the phase prescription developed by sophisticated lens design programs may not be manufacturable. Some simple design examples are presented to illustrate natural and manufacturing constraints.
