摘要：本文提出了利用偏振选择镜对或镜垒阵列实现不同光程长度的深度增强积分三维（3D）成像。该方法通过重新定位两类元素图像平面来增强图像深度，从而有效地获得两个中心深度平面。两种实现方法之一是利用具有不同光程长度和偏振选择性反射镜的双臂结构。另一种利用镜像屏障阵列。使用偏振装置的方法的主要优点是，我们可以在没有任何机械运动部件的情况下，在大深度差的情况下观察到保持一定程度的观看分辨率的3D图像。反射势垒阵列具有厚度紧凑的优点。我们用实验证明并验证了我们的建议。
Abstract— Depth‐enhanced integral three‐dimensional (3D) imaging using different optical path lengths by using a polarization selective mirror pair or mirror barrier array is proposed. In the proposed approach, the enhancement of image depth is achieved by repositioning two types of elemental image planes, thus effectively two central depth planes are obtained. One of the two implementation methods makes use of the two‐arm structure that has different optical path lengths and polarization‐selective mirrors. The other utilizes the mirror barrier array. The primary advantage of the method with polarization devices is that we can observe 3D images that maintain some level of viewing resolution with a large depth difference without any mechanical moving part. The mirror barrier array has the advantage of the compact thickness. We demonstrated and verified our proposals experimentally.
