Abstract

Due to its ease of processing and modulation, pixelated spatial light modulators (SLMs) are extensively used in the applications where wavefront modulation is needed, including holographic displays, optical manipulation, diffractive optics, and beam physics. Many prevailing diffraction calculation methods are predicated on the premise of band-limited input fields, which have been proven to be inefficient and inaccurate when computing the diffraction field of a pixelated SLM in some cases where the influences from high diffraction orders are not neglectable. Here we present a diffraction computation framework for efficient computing of the wave propagation from a pixelated SLM. Numerical and optical experiments are presented to verify the analysis.
