Paper Abstract

A device for three-dimensional (3D) photoacoustic tomography with resolution in the range of tens of micrometers is presented. It is based on a focused laser beam as detector, which propagates near the imaging object in a water bath and is part of a Mach-Zehnder interferometer. By scanning the beam relative to the object, data for 3D image reconstruction are acquired. Using a phantom consisting of human hairs, the resolution of the setup is demonstrated. Using a flea and an excised mouse heart as samples, the imaging capabilities of the device for complex biological objects are shown.
