Abstract

A technique for designing a multipass optical cell utilizes an iterative artificial intelligence-based optimization process based upon evaluation of direct ray tracing with mirrors simulated as having true spherical surfaces (i.e., defined as a “thick lens”) to identify particular cell configurations that result in creating spot patterns which fill a significant portion of the surface of each mirror without significant spot overlap. This technique allows the use of relatively simple, low-cost spherical mirrors while providing the desired dense spot patterns.
