Resolution comparison between integral-imaging-based hologram synthesis methods using rectangular and hexagonal lens arrays

Opt Express. 2011 Dec 19;19(27):26917-27. doi: 10.1364/OE.19.026917.

Abstract

We compare the resolution of the hologram reconstruction synthesis methods based on integral imaging using rectangular and hexagonal lens arrays. By using a hexagonal lens array instead of conventional rectangular lens array, the three-dimensional objects are sampled with hexagonal grids. Due to more efficient sampling of the hexagonal grid, the resolution of the reconstructed object is higher compared with the case of using rectangular lens array. We analyze the resolution enhancement of the hologram reconstruction quantitatively and verify it experimentally.
