Abstract :
A key element of optoacoustic diagnostics, which employs short laser pulses to generate ultrasonic pressure transients in tissues is besides a homogeneous illumination the optimum design of the pressure transducer. Different piezo-electrically and optically based pressure transducers will be compared and discussed.
