A depth-enhanced three-dimensional integral imaging system with electrically variable image planes is proposed. For implementing the variable image planes, polymer-dispersed liquid-crystal (PDLC) films and a projector are adopted as a new display system in the integral imaging. Since the transparencies of PDLC films are electrically controllable, we can make each film diffuse the projected light successively with a different depth from the lens array. As a result, the proposed method enables control of the location of image planes electrically and enhances the depth. The principle of the proposed method is described, and experimental results are also presented.
提出了一种具有电可变像平面的深度增强型三维积分成像系统。为了实现可变像平面，采用聚合物分散液晶（PDLC）薄膜和投影仪作为积分成像中的一种新型显示系统。由于PDLC薄膜的透明度是电可控的，我们可以使每个薄膜以与透镜阵列不同的深度依次散射投影光。结果，该方法能够通过电控制像平面的位置并增强深度。描述了该方法的原理，并给出了实验结果。
