摘　　要：光场显示具有数据量小、结构简单、易于集成化等优点,使其在军事、医学、教育、娱乐等领域具有巨大的应用潜力。然而,全彩色、大视角、高分辨率、大景深的光场显示受限于高分辨率显示器、光调制器、智能算法、超高速计算机等技术的发展。近年来,人们致力于探索新的设计策略、新的器件结构和潜在的应用。综述了三维(3D)显示技术的发展与分类以凸显出光场显示的优势;阐述了光场显示的概念与意义;介绍了光场显示中的集成成像光场显示、投影光场显示和层光场显示的发展及主要技术挑战。强调了在新形势下对光场显示的新要求,并提出对中国发展光场显示的建议,即加强技术创新平台建设,推动光场显示与其他前沿技术的融合,重点攻克关键技术和产业链瓶颈,促进产学研合作,以确保在全球高科技领域的竞争力。With the benefits of small data volume,simple structure,and easy integration,light field display(LFD)has a great potential to be applied in military,medical,educational,entertainment,and other fields.However,the LFD with full color,large field of view,high-resolution,and big depth of field was limited by the high-resolution displays,light modulators,intelligent algorithms,ultra-fast computers and other technologies.Recently,efforts were made to investigate novel design methodologies,new device structure,and prospective applications.In this article,the evolution and classification of three-dimensional display technologies were reviewed to illustrate the benefits of LFD.Then,the concept and importance of LFD were explained.Following that,a full overview of the evolution and major technical issues of integrated imaging LFD,projection LFD,and layer LFD was provided.Finally,the new requirements for LFD in novel setting were presented and recommendations for LFD development in China were highlighted.LFD can perfectly duplicate real 3D scenes and match the viewing characteristics of the human eye,therefore it has a broad application prospect.To promote technological progress in the field in China,suggestions were made to strengthen the construction of technology innovation platforms,promote the integration of LFD with other innovative technologies,prioritize key technological breakthroughs and industry chain bottlenecks,promote industry-university research cooperation,and ensure global high-tech competitiveness.
