Abstract
Holographic displays give users a realistic experience by allowing them to perceive three‐dimensional (3D) images without any visual aids such as glasses. However, in a holographic display using liquid crystal based spatia/light modulator (LC‐SLM), the pixel pitch is not small enough so that the images are realized in limited areas. In addition, the slow framerate of LC‐SLM makes temporal multiplexing practically impossible. We propose holographic display using digital micromirror device (DMD) and apply temporal multiplexing method. The proposed system enhances viewing angle through temporally switched directional illuminations. Besides, the DMD's sufficient framerate provides significant reduction in speckle noise of holograms. We experimentally show the feasibility of proposed method by reconstructing holograms of 3D objects.
