Photoacoustic apparatus and method for controlling the same

摘要

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.

1. A photoacoustic apparatus comprising:
a light source configured to emit light; an optical system configured to guide the light from the light source to an analyte; a detecting unit including a receiving element configured to receive an acoustic wave that is 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 that is acquired from the detecting unit; and a calculation unit configured to calculate an irradiation intensity distribution of the light from the optical system on the basis of the detected signal that is acquired when the receiving element receives acoustic wave generated from an optical absorber configured to absorb the light from the optical system.
