狭缝光栅、柱面透镜光栅及其新构型在三维显示中的应用

介绍了三维显示技术的研究现状,综述了狭缝光栅和柱面透镜光栅在自由立体显示技术中的重要应用。回顾了各种光栅式自由立体显示系统的结构和原理;提出了如何根据狭缝光栅和柱面透镜光栅的特殊光学性质,在传统的立体显示系统中添加各种光栅形成灵活组合结构来提高立体显示效果,强调了它们在减小串扰、增大视场角、避免摩尔条纹以及提供更全面的三维信息等方面的作用。最后指出基于两种光栅的叠加构成面积大、参数均匀、价格低廉的新型透镜可实现全视差立体显示,对探索自由立体显示技术的研究很有意义。

Applications of parallax barrier,lenticular lens array and their modified structures to three-dimensional display

The present situation of Three-dimensional（3D） display technology is introduced and applications of parallax barriers and lenticular lens arrays to 3D display technology are overviewed.The structures and principles of several kinds of parallax barriers and lenticular lens arrays are given.Then,it describes how to add the different gratings into the traditional stereoscopic display systems to form a combined structure to improve stereoscopic display function of the system,and emphasizes the effects of these gratings on reducing cross-talk and moiré fringes,enlarging viewing-angles,and providing full 3D information.Finally,it points out that it is significant to combine two lenticular lens sheets to form a new lens array with a large area,low cost and uniform parameters for researching free stereoscopic display technology.
