Optimum Design of Optical System for Free Space Optics Device by Ray Tracing

Abstract

It is necessary to generate parallel laser beam reducing its diffusion to realize long distance Free Space Optics. The locus of the propagating laser beam is influenced by the shape and physical characteristics of the optical system such as lens, mirrors. Geometric optics is analyzed in terms of parameters of lens thickness, radius of curvature, lens position using an optical design simulator. Parallelism is evaluated by ray tracing, and the Free Space Optics optical system is optimized.
