Abstract

We propose a full-color complex holographic display system design comprised of three R/G/B amplitude-only spatial light modulators and an achromatic Fourier filter. A key feature of the design is a single achromatic Fourier bandpass filter for robust axial R/G/B color matching, whereby the R/G/B holographic image light fields can be three-dimensionally aligned. The synthesis algorithm producing the full-color computer-generated holograms for this system is described and a full-color optical reconstruction of the designed holographic three-dimensional images is experimentally demonstrated.

Highlights

Nowadays, full-color holographic three-dimensional (3D) display systems are being actively researched [1,2,3]
The research on the system level configurations of holographic 3D display systems has preceded the research on display device architectures
This paper proposes a holographic 3D display system configuration comprised of three amplitude-only spatial light modulator (SLM) for R/G/B components and an achromatic Fourier band-pass filter providing robust axial color alignment capabilities, and develops an optimal full-color computer-generated holograms (CGH) synthesis algorithm for this system

Summary

Introduction

Full-color holographic three-dimensional (3D) display systems are being actively researched [1,2,3]. The main goal of the research is to achieve full-color high-resolution holographic 3D displays featuring wide-viewing angles [4] and extended viewing windows [5] from which observers can enjoy comfortable holographic 3D images. This is beyond the ability of current display technology and requires technological breakthroughs to solve many challenging issues. The research on the system level configurations of holographic 3D display systems has preceded the research on display device architectures. Personal wearable VR and AR smart displays are less affected by limited viewing angles and viewing-window size [16, 17]
