Abstract

We propose a geometrical optics approach to calculating the eikonal function of a light field on the assumption of generating a desired intensity distribution in a given focal plane region. To solve the focusing problem in a more efficient way, we modify a conforming rectangles method used to design diffractive optical elements (DOE) to focus into plane regions. The novelty consists in a technique for reconstructing the eikonal function based on the known ray mapping relation between the DOE points and focal plane points. Results of focusing into a rhomb are presented. Simulation results show high quality of focusing, also corroborating the efficiency of the proposed method.
