Freeform optical systems with prescribed irradiance properties in near-field

摘要

The problem of design of a reflector system for redirecting and reshaping the irradiance distribution of a point source over a prescribed target set in the near-field is considered. The solution of this problem is developed under the geometrical optics (GO) approximation. The novelty is that our method is not limited to the usual input and/or output irradiance profiles which are rotational or rectangular symmetric. Consequently, the designer has more flexibility in satisfying the requirements of a practical design problem.
