<p>PROBLEM TO BE SOLVED: To provide a photoacoustic device capable of suppressing deterioration in a quantitative property of optical characteristic information due to a composition corresponding to a reflective wave of a photoacoustic wave.SOLUTION: A photoacoustic device includes: a light source that emits light; an acoustic wave transmitter that transmits an acoustic wave to a specific region; a photoacoustic wave receiver that receives a photoacoustic wave generated from a subject when the subject is exposed to the light emitted from the light source, and outputs a time-series photoacoustic signal; an echo receiver that receives an echo generated when the acoustic wave transmitted from the acoustic wave transmitter is reflected in the subject, and outputs a time-series echo signal; and a processor that acquires subject's optical characteristic information which includes a reduced composition corresponding to a reflective wave of the photoacoustic wave generated in the specific region, on the basis of the time-series photoacoustic signal and the time-series echo signal.</p> |
