Abstract

Complex spatial light modulator (SLM), which can simultaneously control the amplitude and phase of light waves, is a key technology for wide-range of wave-optic technologies including holographic three-dimensional displays. This paper presents a flat panel complex spatial light modulator that consists of dual in-plane switching liquid crystal panels with double-degrees of freedom of voltage inputs. The proposed architecture features single-pixel level complex light modulation enabling complex light modulation in entire free space, which is most contrast to conventional macro-pixel based complex modulation techniques. Its complex light modulation capability is verified with theoretical simulation and experimental characterization, and a three-dimensional holographic image reconstruction without conjugate noise. It is believed that the proposed flat panel complex SLM can be an essential device for a wide range of advanced wave optic technologies.

摘要

复杂空间光调制器（SLM）能够同时控制光波的幅度和相位，是包括全息三维显示在内的广泛波光学技术的关键技术。本文提出了一种平板复杂空间光调制器，它由具有双自由度电压输入的双平面内切换液晶面板组成。所提出的架构具有单像素级复杂光调制能力，可在整个自由空间中实现复杂光调制，这与传统的基于宏像素的复杂调制技术形成了鲜明对比。通过理论模拟和实验表征验证了其复杂光调制能力，并实现了无共轭噪声的三维全息图像重建。据信，所提出的平板复杂SLM可以成为广泛先进波光学技术的重要器件。
