A scanning acoustic and photoacoustic microscope is demonstrated. The laser illumination and ultrasound detection in the system are co-axial. Pulsed light from a tunable optical parametric oscillator (OPO) laser is delivered to the scan tank via optical fiber. Multiple acoustic transducers with center frequencies varying from 5 MHz to 25 MHz are utilized. Images of a pig kidney (ex vivo) and a microcalcification phantom (eggshells embedded in agarose) are shown.
