Abstract
A novel method of encoding a phase hologram that uses less than π radians of phase is described. The technique is based on Lee's delayed sampling method for amplitude holograms. It was devised for use with liquid crystal spatial light modulators with limited phase modulation capability. Results are compared with Lee's method and binary phase holograms and show improved image quality.
