PROBLEM TO BE SOLVED: To provide a photoacoustic imaging apparatus capable of reducing processing load in a controlling part.SOLUTION: A photoacoustic imaging apparatus 100 comprises: a light absorber 2 having absorbed light from a light source part 1a(1b); a detecting part 3 detecting acoustic wave from a detection object; an acoustic wave conducting member 4 which comprises a contacting surface 4a being arranged at a side of a sampling object relative to the detecting part 3, the light source part 1a(1b) and the light absorber 2 and contacting to the sampling object and an inner surface 4b opposing to the detecting part 3 and the light source part 1a(1b) at a side of the detecting part 3 and the light source part 1a(1b) rather than the contact surface 4a and being provided with the light absorber 2 at a part thereof, transmits light and conducts acoustic wave to the detecting part 3; and a controlling part 5 executing first stop control in which light from the light source part 1a(1b) is shaded in a case where the acoustic wave detected by the detecting part 3 has a strength of a predetermined threshold or more.SELECTED DRAWING: Figure 1 |
