This paper presents the design of a digitally switchable multi-focal micro lens array to extend the depth of field without sacrificing the spatial resolution in integral imaging systems. The switchable multi-focal micro lens array consists of a customized freeform micro lens array and a programmable spatial light modulator. A prototype with two foci was fabricated and focus tuning functionality was demonstrated using an LCoS together with a relay system.
