We propose a real-time spatiotemporal division multiplexing electroholography utilizing the features of movies. The proposed method spatially divides a 3-D object into plural parts and periodically selects a divided part in each frame, thereby reconstructing a three-dimensional (3-D) movie of the original object. Computer-generated holograms of the selected part are calculated by a single graphics processing unit and sequentially displayed on a spatial light modulator. Visual continuity enables a reconstructed movie of the original 3-D object. The proposed method realized a real-time reconstructed movie of a 3-D object composed of 11,646 points at over 30 frames per second (fps). We also displayed a reconstructed movie of a 3-D object composed of 44,647 points at about 10 fps.
我们提出了一种利用电影特性的实时时空分割复用电子全息术。该方法将三维物体在空间上划分为多个部分,并在每一帧中周期性地选择一个划分后的部分,从而重建原始物体的三维电影。所选部分的计算机生成全息图由单个图形处理单元计算,并顺序显示在空间光调制器上。视觉连续性实现了原始三维物体的重建电影。该方法实现了由11646个点组成的三维物体以每秒30帧以上的帧率实时重建电影。我们还以约每秒10帧的速度显示了由44647个点组成的三维物体的重建电影。
