Title:
PHOTOACOUSTIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/103374
Kind Code:
A9
Abstract:
To provide a photoacoustic device wherein measurement accuracy of absorption coefficient can be improved by acquiring information of a subject after performing correction corresponding to the quantity of light applied to the subject. This photoacoustic device has: an acoustic wave detection unit, which detects photoacoustic waves generated from a subject when light emitted from a light source is applied to the subject, and which outputs a detection signal; and a signal processing unit that performs, on the basis of the detection signal, signal processing for acquiring information of the subject. The photoacoustic device is characterized in that, at the time of acquiring the information of the subject, the signal processing unit acquires the information of the subject after performing correction corresponding to the quantity of light applied to the subject.
