METHOD FOR OPTIMIZING A FRESNEL OPTICAL LENS

摘要

A method implemented by computer means to optimize an optical lens suitable for a wearer, the method comprising: an initial optical system providing step (S1) in which an initial optical system is provided, wherein the initial optical system comprises a light source 10, an optical receiver ( 12) and an initial optical system (L) comprising at least an initial optical lens (L0) disposed between the light source (10) and the optical receiver (12), the initial optical lens comprising at least a Fresnel zone (S1), A cost function associated with the number of rays received by the optical receiver 12, passing through the annular step of the processing optical lens, step S2, in which the processing optical lens is defined to be the same as the initial optical lens L0. It comprises an evaluation step (S3) to be evaluated, and a correction step (S4) in which the annular step of the processed optical lens is corrected, and the evaluation step and the correction step are repeated to minimize the cost function.
