Paper Abstract

The depth of field of optical systems can be extended with a phase mask placed in the pupil. We propose to design this phase mask through a heuristic numerical optimization. We describe two different criteria to illustrate the technique. We present the obtained phase profiles and we show that they have good properties regarding the extension of the depth of field.
