Resolution and intensity distribution of output images reconstructed by sampled computer-generated holograms.

We address reconstruction abilities of computer-generated holograms that are fabricated in a sampled form and designed for spherical-wave illumination. Our approach enables one to define the limit of resolution of the object reconstruction and the light-intensity distribution in an output plane. The analysis takes into account a hologram aperture, a sampling aperture, and a curvature radius of spherical illumination. Theoretical results are confirmed by experimental verification.
