Proceedings Article | 6 May 2022 Paper

Lenses behavior simulation using Matlab

Dana Rizescu, Ciprian Ion Rizescu

Proceedings Volume 12170, 1217008 (2022) https://doi.org/10.1117/12.2601969

KEYWORDS: Lenses, Ray tracing, Geometrical optics, Interfaces, Computer simulations, Refraction, MATLAB, Refractive index, Optical simulations

Read Abstract +

The paper is focused on the behavioral simulation of the lenses, defined by geometric characteristics (radius, thickness and diameter) and material characteristics, for a certain incident wavelength. The simulation provides a representative layout of the raytracing for refraction and for the second and third reflection on lens surfaces. At the same time, the user can display the rays distribution on a normal plane related to optical axis direction. The authors designed the simulation program and a graphic user interface as a tool to evaluate the parasite images caused by multiple reflections in the specter available for chosen material. Thus, the image disparity for a certain parameter will influence the transmittance through lenses for some radiation or specter. The simulation program is designed to be used in optics, optometry, to analyze the behavior of refractive components and can predict the useful diameter of lenses, diaphragms or aperture stop. The program is also useful, for example, for anyone interested to see how lenses work if the internal reflection of the light on the lens surfaces is considered. The idea of the program comes from the fact that with other ray tracing software and their toolboxes, the multiple reflections are not obvious. The developed simulation program and interface can highlight the ray distribution in an image plane as being suggestive for the ghost images presence and of lens aberrations. Also, there can be easily predicted some geometrical placements in the optical layout, the dimensions of the main apertures and the position of the second order images due to multiple reflection and refraction.

The simulation of the behavior of lenses in the telecentric incident beam

Dana Rizescu, Aurelian Trufasu, Ciprian Rizescu

Proceedings Volume 5227, (2003) https://doi.org/10.1117/12.519795

KEYWORDS: Geometrical optics, Lenses, Refraction, Reflection, Optical simulations, Interfaces, Ray tracing, Minerals, Contact lenses, Glasses

Read Abstract +

The paper is focused on the behavioral simulation of the mineral and organic lenses, defined by geometric characteristics (the accumulation radius, thickness, diameter) [2] and material characteristics, for a certain incident wavelength [2]. The simulation provides a picture of the ray-tracing for the second and third reflection/refraction. At the same time, the user can display the print of a ray on a normal plane related to optical axis direction. The authors designed the simulation program, aimed to evaluate the wounded through the multiple reflections in the spectre available for chosen material. On this way, the disparity of a certain parameter will influence the transference through lenses for some radiation or spectre. The paper is designed to be used in optics, to shape the refractive/reflective components, and can predict the useful diameter of lenses, diaphragms or aperture stop; the paper is a guide for qualified professors to simulate the route of telecentric fascicle, after multiple reflection and refraction, to illustrate Snell’s law, all of them by changing the optical and geometrical characteristic of lenses.
