Abstract
Provided is a photoacoustic apparatus capable of recognizing light quantity unevenness, which occurs on a surface of an analyte, and decreasing image unevenness resulted from the light quantity unevenness. A photoacoustic apparatus includes a light source configured to irradiate an analyte with light; an optical system configured to guide the light from the light source to the analyte; a detecting unit including a receiving element configured to receive an acoustic wave generated in the analyte by the light; a signal processing unit configured to acquire information about the inside of the analyte from a detected signal acquired from the detecting unit; an optical absorber configured to absorb the light from the light source; and a calculation unit configured to calculate an irradiation intensity distribution of the light on the basis of a detected signal acquired when the receiving element receives the acoustic wave generated from the optical absorber.
