Abstract
We report on diffraction efficiency considerations and experimental implementation of diffraction gratings by means of a phase-only spatial light modulator, parallel aligned (PAL) liquid crystal on silicon (LCoS) display. We present results of the implementation of continuous phase profiles for optimal efficiency, and their application for blazed gratings and diffractive lenses onto displays with reduced phase modulation range and also onto displays with large phase modulation range.
