| 摘 要： | 为解决传统柱透镜自由立体投影显示中像差和视几何引起的串扰和视点数受限问题，基于回归反射，提出了一种棱镜反射光栅自由立体投影显示方法。通过分析其3D成像的原理，对棱镜反射光栅自由立体投影显示进行仿真，发现该方法在水平视宽相同的条件下，视场照度是柱透镜光栅投影的10倍，而其串扰比是柱透镜光栅投影的1/5，且不存在次视区。制作了棱镜反射光栅屏，并搭建系统进行实验，验证了棱镜反射光栅自由立体投影显示方案的可行性。

| Abstract: | In order to solve the problem of crosstalk and limited number of viewpoints caused by aberrations and geometry in the traditional stereoscopic projection display based on cylindrical lens, a autostereoscopic projection display method based on prismatic reflective grating was proposed. The principle of 3D imaging was analyzed. The autostereoscopic projection display based on prismatic reflective grating was simulated. Compared with traditional autostereoscopic projection display based on cylindrical lens, under the condition of same horizontal video bandwidth, the illuminance of viewing field is ten times, and the crosstalk ratio is 1/5, and there is no secondary viewing zone. The prismatic reflection grating screen was made and the system was set up to carry out experiments. The feasibility of autostereoscopic projection display was verified. |
