Abstract

Techniques for encoding composite diffractive optical elements (DOEs) oriented to the use of spatial light modulators (SLM) are discussed. The use of the dynamic SLMs presupposes the real-time encoding. It turns out to be effective to use the composite DOEs, with their complex transmission function being derived as a superposition of Fourier (or Fresnel) images of the corresponding image segments (spots, line-segments). Composite DOEs to form desired images in different planes are considered. A modification to the fractional encoding technique where every pixel of the amplitude-phase function is encoded into a single phase function pixel is proposed.
