介绍了一种三维光声显微镜系统，该系统采用光学MEMS和光纤探头作为有源元件，实现全光定位和读出。使用静电致动的2轴MEMS扫描仪控制激发光束位置。这允许快速3D扫描而没有由载物台扫描引起的运动诱导伪影，以及感兴趣区域的选择性成像。一个20 MHz的光纤尖端传感器用于声学检测，这允许使用各种样品架，包括常见的方法，如多孔板和培养皿。
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.
