Abstract
We show that long depth of focus can be achieved with a pixelated lens (PL) encoded onto a reconfigurable spatial light modulator (SLM). Our PL has a phase distribution similar to that of a conventional axilens. Additionally, our resulting reconfigurable PL is employed in a novel shape recovering system. A feature of this system is that no moving parts or motors are required to scan a three-dimensional object. Numerical simulations and experimental results are shown.
