Abstract

A 3D photoacoustic microscopy (PAM) system is presented and characterized, using optical MEMS and fibre tip transducers as active elements to provide all-optical positioning and read-out. The excitation beam position is controlled using an electrostatically actuated 2-axis MEMS scanner. This allows for fast 3D scanning without motion-induced artefacts caused by stage scanning, and selective imaging of regions of interest. A 20 MHz fibre tip transducer is used for acoustic detection, which allows a variety of sample holders to be used including common approaches such as multi-well plates and petri-dishes.
