Abstract
A biological information imaging apparatus includes: a light source; an acoustic wave detector that detects an acoustic wave generated from a light absorption material in a living body that has absorbed a part of energy of light irradiated from the light source to the living body, and converts it into a first electric signal; a photodetector that detect optical intensity of a portion of the light irradiated from the light source to the living body and propagating in the living body, and converts it into a second electric signal; and a calculation unit that calculates optical property distribution information on the living body by making use of an analytical result of one of the first electric signal and the second electric signal for analysis of the other electric signal.
