OBJECT INFORMATION ACQUIRING APPARATUS AND METHOD OF CONTROLLING THE SAME

摘要

An object information acquiring apparatus is used, which includes: a light source emitting pulsed light of first and second wavelength at different time; a delay optical system delaying the first wavelength pulsed light relative to the second wavelength pulsed light; a conversion element receiving photoacoustic waves generated from an object and outputting reception signals; a photodetector detecting light quantities of the pulsed light; and a processor acquiring characteristics information of the object based on the reception signals and the light quantities.
