Abstract

Normally, to incorporate two binary conventional computer-generated holograms (CGHs) into a single polarization-selective computer-generated hologram (PSCGH), the respective pixels of the conventional CGHs will result in 4 different combinations of the phase values. Thus, the 4 phase combinations have to be realized by 4 types of pixel structures in a PSCGH. In this paper, we propose a method to reduce the PSCGH’ s 4 phase combinations to 3 using an optimization approach. The PSCGH’s first-order diffraction efficiency is 30% and the contrast ratio is 28 after the optimization.
