Paper Abstract

An optical phase contrast full field detection setup in combination with a CCD-camera is presented to record acoustic fields for real-time projection and fast three-dimensional imaging. When recording projection images of the wave pattern around the imaging object, the three-dimensional photoacoustic imaging problem is reduced to a set of two-dimensional reconstructions and the measurement setup requires only a single axis of rotation. Using a 10 Hz pulse laser system for photoacoustic excitation a three dimensional image can be obtained in less than 1 min. The sensitivity and resolution of the detection system was estimated experimentally with 5 kPa mm and 75μm, respectively. Experiments on biological samples show the applicability of this technique for the imaging of blood vessel distributions.
