Abstract
A photoacoustic apparatus includes a laser light irradiating unit that irradiates an inside of a subject with pulsed light; a photoacoustic signal acquiring unit that acquires a photoacoustic signal from a photoacoustic wave from the subject; a light amount detecting unit that detects a light amount of the pulsed light; a correlation data memory that stores first correlation data and second correlation data; an energy estimating unit that estimates an energy on the basis of the amount of the pulsed light and the first correlation data; a pulse width estimating unit that estimates a pulse width on the basis of the estimated energy and the second correlation data; and a photoacoustic signal correcting unit that corrects the photoacoustic signal on the basis of a first difference between the estimated energy and a reference energy and a second difference between the estimated pulse width and a reference pulse width.
