Abstract
In an acoustic wave detection probe provided with a light guide section that guides measuring light such that the measuring light is outputted toward a subject and an acoustic wave transducer that detects a photoacoustic wave generated in the subject by the projection of the measuring light, the light guide section includes a homogenizer that flat-tops an energy profile of the measuring light entered from the upstream side of the optical system, a light condensing member that condenses the measuring light transmitted through the homogenizer, and a. bundle fiber which includes a plurality of optical fibers and is disposed such that the measuring light transmitted through the light condensing member enters from an entrance end of the bundle fiber.
