Abstract

Digital holography is a technology that can recognize for us hologram of three-dimensional (3D) object. If we observe a noise-free reconstructed image, it is required to modulate simultaneously amplitude and phase for single pixel of computer generated hologram (CGH). However, conventional design technique of holographic display has an issue that occurs low quality and significant noise because it can modulate only one element such as amplitude-only or phase-only. Recently, for solving this issue, meta-surface technology has been researched and developed, which is able to control complex spatial light modulation by structural specification [1-3]. In this study, we propose a new pixel design that is able to modulate simultaneously amplitude and phase. Also, we analyzed characteristics of complex modulation of unit-pixel using wave optical simulations. Based on this results, we verified increasing a quality of reconstructed image for low noise hologram.
