We propose an improved projection-type integral imaging system using a three-dimensional (3D) screen consisting of a lens array and a retroreflector film in this paper. The projection-type integral imaging system suffers from the disadvantage of low-visibility images because of the inherently small exit pupil size of the projector. In order to resolve this problem, we adopt a 3D screen to avoid the demerits of a diffuser screen, such as off-screen image blur and loss of parallax. To determine the appropriate configuration of the 3D screen in the system, a simulation based on a ray transfer matrix analysis method was performed. The results show that the 3D screen should be located near the central depth plane of the integral imaging system, which leads to the conclusion that only the real mode is available for the proposed system. Experiments to verify this configuration and the feasibility of the proposed system were conducted using a system constructed with a real mode integral imaging system including a convex mirror array, which can fundamentally eliminate the pseudoscopic problem.
本文提出了一种改进的投影型积分成像系统，该系统使用由透镜阵列和后向反射膜组成的三维（3D）屏幕。由于投影仪固有的出瞳尺寸小，投影型积分成像系统存在图像可视性低的缺点。为了解决这个问题，我们采用3D屏幕来避免漫射屏幕的缺点，如屏幕外图像模糊和视差损失。为了确定系统中3D屏幕的合适配置，基于光线传输矩阵分析方法进行了模拟。结果表明，3D屏幕应位于积分成像系统的中心深度平面附近，由此得出结论，所提出的系统仅实模式可用。使用包括凸面镜阵列的实模式积分成像系统构建的系统进行了实验，以验证这种配置和所提出系统的可行性，该系统可以从根本上消除伪视问题。
