We developed an all-optical 3D photoacoustic imaging probe consisting of an optical fiber probe for ultrasound detection and a bundle of hollow optical fibers for excitation of photoacoustic waves. The fiber probe for ultrasound is based on a single-mode optical fiber with a thin polymer film attached to the output end surface that works as a Fabry Perot etalon. The input end of the hollow fiber bundle is aligned so that each fiber in the bundle is sequentially excited. A thin and flexible probe can be obtained because the probe system does not have a scanning mechanism at the distal end.
