conference on current developments in lens design and optical engineering XIV
作者: Moreno, Ivan Rodriguez, Nayeli Carlos Basilio, Jose Univ Autonoma Zacatecas Unidad Acad Fis Zacatecas 98060 Mexico
A compact encapsulating lens is proposed and analyzed, which simultaneously collimates and mixes the tunable light from red, green and blue (RGB) light-emitting diode (LED) chips. Colored LED chips are embedded within... 详细信息

作者: Doherty, Victor J. Aouani, Dina Eidolon Opt LLC 3 Erie Dr Natick MA 01760 USA
Conventional round spot quadrant detector trackers are inherently non-linear. This non-linearity requires multiple iterations to converge onto perfect alignment with the object tracked. We created a system that genera... 详细信息

作者: Zhang Xin Zheng Ligong He Xin Wang Lingjie Zhang Feng Yu Shuqin Shi Guangwei Zhang Binzhi Liu Qiang Wang Tongtong Changchun Inst Opt Key Lab Opt Syst Adv Mfg Technol Changchun 130033 Peoples R China
Freeform surfaces provide more degrees of freedom for design of optical systems, and enhance the ability of compensation and correction aberrations. Freeform surfaces are of advantage to balance the unsymmetrical aber... 详细信息
