FOCUSING OF TWO-DIMENSIONAL WAVES
收藏 引用
JOURNAL OF THE OPTICAL SOCIETY OF AMERICA 1981年 第1期71卷 15-31页
作者: STAMNES, JJ Central Institute for Industrial Research Forskningsveien 1 Blindern Oslo 3 Norway
Two different methods are presented for efficient computation of two-dimensional wave fields in focal regions. Both methods are valid for arbitrarily large relative apertures. One method is based on the impulse-respon... 详细信息

Light field displays with computational vision correction for astigmatism and high-order aberrations with real-time implementation
收藏 引用
OPTICS EXPRESS 2023年 第4期31卷 6262-6280页
作者: Qiu, Yuqing Zhao, Zhiqing Yang, Jinglan Cheng, Yunfan Liu, Yi Yang, Bo-ru Qin, Zong Sun Yat sen Univ Sch Elect & Informat Technol Guangdong Prov Key Lab Display Mat & Technol State Key Lab Optoelect Mat & Technol 132 East Waihuan Rd Guangzhou 510006 Peoples R China
Vision-correcting near-eye displays are necessary concerning the large population with refractive errors. However, varifocal optics cannot effectively address astigmatism (AST) and high-order aberration (HOAs);freefor... 详细信息

Enhanced field-of-view integral imaging display using multi-Kohler illumination
收藏 引用
OPTICS EXPRESS 2014年 第26期22卷 31853-31863页
作者: Tolosa, Angel Martinez-Cuenca, Raul Navarro, Hector Saavedra, Genaro Martinez-Corral, Manuel Javidi, Bahram Pons, Amparo Technol Inst Opt Color & Imaging AIDO E-46117 Paterna Spain Univ Jaume 1 Dept Mech Engn & Construct E-12071 Castellon de La Plana Spain Univ Valencia Dept Opt E-46100 Burjassot Spain Univ Connecticut Dept Elect & Comp Engn Storrs CT 06269 USA
A common drawback in 3D integral imaging displays is the appearance of pseudoimages beyond the viewing angle. These pseudoimages appear when the light rays coming from each elemental image are not passing through the ... 详细信息
