Paper Abstract

The light intensity distribution near focus of an optical system can be modified by pupil-plane masks. In fact, in some relevant fields, such as optical data storage or confocal microscopy, there is an increasing interest in the design of pupil masks for controlling the Point Spread Function (PSF). These techniques present a great advantage for educational purposes, since they deal with current technology but at the same time illustrate basic diffraction principles. In this work, we introduce a simple low-cost set up that allows the dynamical control of the PSF and can be easily implemented in any educational centre.
