title = "Inverse methods for freeform optical design",
abstract = "We present several geometrical models for freeform optical design based on Hamilton{\textquoteright}s characteristic functions, which can be either expressed in terms of a cost function or a generating function. These models are closed with a conservation law for luminous flux. We give an example of a near-field problem where a collimated beam is converted into a target distribution on a sphere.",
