Abstract:
Disclosed are a probe for photoacoustic measurement which can suppress generation of artifacts obstructive to signal observation in a photoacoustic measurement, and a photoacoustic measurement apparatus including the same. The probe for photoacoustic measurement includes a light emission unit which emits measurement light to a subject, and an acoustic wave detection unit which detects a photoacoustic wave generated in the subject by the emission of measurement light. An emission end surface of the light emission unit is positioned to a side where the acoustic wave detection unit is located, with respect to a contact plane of the probe, and an optical axis at the emission end surface is inclined to a side opposite to the side on which the acoustic wave detection unit is positioned with respect to a normal direction of a detection surface of the acoustic wave detection unit.
