Abstract

Wave-optics and ray-field tracing methods for the simulation of micro-lens arrays (MLAs) taking into account the coherence and polarization effects of light source, randomization of microlens array parameters are implemented. The influence of the parameters of radiation source (wavelength, wavefront curvature, beam radius, coherence radius, etc.) and micro-lens array (periodic or random, aspect ratio, pitch size, refractive index, array surface shape and profile (convex, concave), etc.) on the output parameters (intensity distribution, radiation pattern, optical efficiency) of a diffracted beam is investigated. Numerical simulations of the intensity distributions and spreading angle of a diffracted beam have been carried out. The new ray-field approach based on the coherent states representation is developed for calculation of the optical efficiency of the microlens arrays. Such wave beams can be tracked simply through the arbitrary curved surfaces. User Friendly Interface is developed for introducing initial parameters of light source and MLA array and for graphical and data outputs of simulated results.
