Lenticular printing is widely used for outdoor advertisements, giant posters, and stage backgrounds. Current lenticular printing technology has a number of limitations, including a small number of viewpoints, serious crosstalk among viewpoints, and weak stereoscopic perception. In this study, we developed low-crosstalk super multi-view lenticular printing using triplet lenticular lens. Based on the super multi-view vision principle and the optical transmission characteristics of the cylindrical lens, the optical formula of the lenticular lens were derived. The viewing distance is 6 m, the viewing zone length is 3 m, and the number of viewpoints is 59. According to the above viewing requirements, the parameters of the lenticular lens were designed, including the radius of the curvature, and the thickness and the pitch. The light intensity distributions of 59 viewpoints in the viewing zone were simulated using optical software (Zemax and LightTools). The viewpoint width is 50 mm, which is less than a normal adults’ pupillary distance. Triplet cylindrical lenses were arranged in a circular arc to reduce crosstalk among viewpoints; the crosstalk of 59 viewpoints is from 3.9% to 4.8%. Finally, simulation results were verified experimentally. The results show that super multi-view lenticular printing can meet the requirements of auto-stereoscopic perception.

使用三重透镜双凸透镜的低串扰超多视角双凸透镜印刷
双凸透镜印刷广泛用于户外广告,巨型海报和舞台背景。当前的双凸透镜印刷技术具有许多限制,包括较少的视点,视点之间的严重串扰以及较弱的立体感。在这项研究中,我们开发了使用三重双凸透镜的低串扰超级多视图双凸透镜印刷技术。基于超多视角视觉原理和柱面透镜的透光特性,推导了柱面透镜的光学公式。视距为6 m,视区长度为3 m,视点数为59。根据上述视线要求,设计了双凸透镜的参数,包括曲率半径,厚度和球场。使用光学软件(Zemax和LightTools)模拟了视区中59个视点的光强分布。视点宽度为50毫米,小于正常成年人的瞳孔距离。三重圆柱透镜以圆弧形排列,以减少视点之间的串扰。59个观点的串扰率为3.9%至4.8%。最后,对仿真结果进行了实验验证。结果表明,超级多视角双凸透镜印刷可以满足自动立体感知的要求。59个观点的串扰率为3.9%至4.8%。最后,对仿真结果进行了实验验证。结果表明,超级多视角双凸透镜印刷可以满足自动立体感知的要求。59个观点的串扰率为3.9%至4.8%。最后,对仿真结果进行了实验验证。结果表明,超级多视角双凸透镜印刷可以满足自动立体感知的要求。
