Freeform Optics For Illumination State Of The Art Challenges And Presentation of the subject of the conference by jean pierre lauret, optical design team manager at gaggione :"the term "freeform" can refer to a multitude o. State of the art imaging systems. how ever, the drastically increased number of surface coefficients of these freeform surfaces poses severe challenges for the optical design process, such that the deployment of freeform optics has remained limited until now. today, the design of optical systems largely relies on efficient raytracing and optimiza.
Design Of Freeform Optics Brochure Fraunhofer Ilt So called optical freeform elements offer degrees of freedom that can greatly extend the functionalities and further boost the specifications of state of the art imaging systems. however, the drastically increased number of surface coefficients of these freeform surfaces poses severe challenges for the optical design process, such that. These so called optical freeform elements offer degrees of freedom that can greatly extend the functionalities and further boost the specifications of state of the art imaging systems. 10 june 2019 – 12 june 2019 osa, washington, district of columbia united states. freeform optics explores the evolving impact of freeform optical surfaces on optical systems for both imaging and illumination. new fabrication techniques that create optical surfaces that are not surfaces of revolution open an expansive new space for optical. This review focuses on the design of freeform illumination optics, which is a key factor in advancing the development of illumination engineering. the design methods of freeform illumination optics can be divided into two groups: zero étendue algorithms based on ideal source assumption and design algorithms for extended light sources.

This review focuses on the design of freeform illumination optics, which is a key factor in advancing the development of illumination engineering. the design methods of freeform illumination optics can be divided into two groups: zero étendue algorithms based on ideal source assumption and design algorithms for extended light sources. We develop a design method that transforms the illumination design for extended sources to an ideal source problem combined with spatially variant deconvolution, which enables compact and efficient illumination lenses with high optical performance. Freeform illumination design for extended sources is a very challenging but rewarding issue that can benefit a wide range of illumination systems. here, we propose a method that can achieve compact and highly efficient illumination lenses by deconvolving the blur caused by the extent from light sources. we combine the illumination calculation with the mathematical model of spatially variant.
