New Methods for Design and Computation of Freeform Optics.

摘要

Optical devices utilizing freeform optical surfaces must be used when the light sources and/or targets and input and/or output radiation patterns lack special symmetries. In these cases traditional designs constrained by use of a particular symmetry may lead to highly energy inefficient devices. Freeform lenses and mirrors are surfaces designed without any a priori assumed symmetry. Under this effort a unified and rigorous approach to solving wide classes of optical design problems requiring freeform optical surfaces has been developed. Computational methods for such problems have also been introduced and tested.
