Object information acquisition apparatus and the object information - procurement procedures

摘要

An object information acquisition apparatus comprises: a light source, which a first light with a first wavelength λ1 and a second light shines with a second wavelength λ2; a detection unit that detects an acoustic wave in the form of a with the light irradiated object has been produced, and the acoustic wave in which converts a detection signal; and a signal processing unit, the characteristic information of the interior of the object on the basis of the detection signal is acquired. The signal processing unit, the characteristic information to be obtained by performing a subtraction processing between a signal, which as a result of the first light absorbed by hemoglobin was produced, and a signal as a result of the second light absorbed by hemoglobin has been generated.
