FIELD: physics.
SUBSTANCE: device for obtaining information on a subject comprises an acoustic conversion unit configured to receive an acoustic wave generated when the object is illuminated with light and convert the acoustic wave into an electrical signal, and a processing unit configured to obtain surface distribution of light intensity or surface distribution of luminosity from light incident on the surface of the subject, based on information on the shape of the surface of the subject, obtain distribution of light intensity inside the subject based on the surface distribution of light intensity or surface distribution of luminosity and obtain distribution of optical properties inside the subject based on the electrical signal and distribution of light intensity inside the subject. A method of obtaining information on the subject and a non-volatile computer-readable data medium storing a program enable operation of the device.
EFFECT: use of the invention enables to accurately determine distribution of values of optical properties in a subject.
