Color optimization of a full-color holographic stereogram printing system using a single SLM based on iterative exposure control

Abstract

In this paper, color optimization of a full-color holographic stereogram printing system using a single SLM based on iterative exposure is proposed. First, an array of sub-holograms (hogels) is generated effectively within fast computergenerated integral imaging, and fully analyzed phase-modulation for red, green, and blue (RGB) channels of hogel. Then, the generated hogels are recorded into holographic material sequentially where SLM displays the R, G, and B channels of a single hogel via effectual exposure under synchronized control with three electrical shutters for RGB laser illumination to obtain verified color optimization. Numerical simulation and optical reconstructions are implemented.

Simplified digital content generation using single-shot depth estimation for full-color holographic printing system

“…In the full-color hogel printing process, the generated full-color hogels are recorded into holographic material one by one where spatial light-modulator (SLM) displays the phase-modulated RGB channels of a single hogel via time-controlled exposure [16] under the synchronized control with three electrical shutters and RGB laser beam illuminations to achieve the full-parallax 3D reconstruction of printed full-color hologram. The schematic configuration of the full-color HS printing is shown in Fig.…”
