Abstract

Freeform optics offer many advantages when performing complex beam shaping for directed energy applications. A number of design methods are presented utilizing radial basis functions, the Monge Ampere solution to optimal transport theory, as well as a novel phase wrapping approach. These methods allow for the precise manufacturing of singular optical elements such as collimation arrays and phase flatteners. This design study also outlines a modular solution in which multiple of these optics can be combined into a single, low-SWaP housing producing an array of aligned and collimated beams with a simulated power in the bucket of more than 80%.
