WebOct 25, 2024 · In this paper, we present a rigorous analytical solution for the bi-aspheric singlet lens design problem. The input of the general formula presented here is the first surface of the singlet lens; this surface must be continuous and such that the rays inside the lens do not cross each other. The output is the correcting second surface of the singlet; …
WebA method of ray tracing for an aspherical lens with subwavelength periodic structured surfaces has been developed. The ray tracing in the antireflective subwavelength … WebROOT-based simulator for ray tracing (ROBAST) is a non-sequential ray-tracing simulation library for cosmic-ray and gamma-ray telescopes. It is able to simulate complex segmented mirror systems and aspherical lenses, which cannot be easily simulated Geant4 or less expensive ray-tracing simulators. The library is written in C++ and utilizes the ROOT …
WebWe present an efficient ray-tracing technique to render bokeh effects produced by parametric aspheric lenses. Contrary to conventional spherical lenses, aspheric lenses do generally not permit a simple closed-form solution of ray-surface intersections. ... http://cg.skku.edu/pub/papers/2016-joo-egsr-nsrt-crc.pdf

WebFeb 1, 2011 · - bug fix. Toric RayTrace - ray missing surface. If a ray cannot intersect with a surface [ignoring apertures], then a flag is set and the ray trace ceases. For toric raytraces, this ‘ray miss’ was properly detected, but the flag was not set, so the raytrace continued spuriously. The flag is now set appropriately.
