Abstract
A method of designing a transmissive optical element for converting a profile of a light beam from a predetermined input profile to a predetermined output profile is disclosed. The method comprises: calculating a stationary function of a predetermined cost functional selected such that the stationary function satisfies a mapping condition for mapping the predetermined input profile into the predetermined output profile, thereby providing a mapping function. The method further comprises utilizing the mapping function for calculating surface properties of at least a first surface and a second surface of the transmissive optical element.
