We propose a thin and compact integral imaging system using electroluminescent (EL) films as backlight. EL film has the advantage that it can operate continuously even when it is cut or punctured. Using this characteristic, we generate an array of pinholes on EL film to form a point light-source array for reconstructing three-dimensional (3D) images based on integral imaging. The EL pinhole film is attached on another EL film and they are electrically controlled to generate a point light-source array or a surface light source; hence, the system converts between 3D and two-dimensional (2D) modes. Taking advantage of the flexibility of EL films, we also propose a flexible 3D/2D convertible integral imaging system with a wide viewing angle using a curved EL film. We explain the principle of the proposed methods and present experimental results.
我们提出了一种使用电致发光(EL)薄膜作为背光源的轻薄紧凑的集成成像系统。EL薄膜具有即使被切割或刺破也能持续工作的优点。利用这一特性,我们在EL薄膜上生成针孔阵列,以形成用于基于集成成像重建三维(3D)图像的点光源阵列。EL针孔薄膜附着在另一块EL薄膜上,并且对它们进行电控制以生成点光源阵列或面光源;因此,该系统可在3D模式和二维(2D)模式之间转换。利用EL薄膜的柔韧性,我们还提出了一种使用弯曲EL薄膜的具有宽视角的柔性3D/2D可转换集成成像系统。我们解释了所提出方法的原理并展示了实验结果。
