<P>PROBLEM TO BE SOLVED: To provide, in a test object information acquisition device for acquiring an optoacoustic signal using light of a plurality of wavelengths, a technology capable of suppressing the effect of an error due to a move of the test object. <P>SOLUTION: A test object information acquisition device includes a light source part for radiating the pulsed light of the plurality of the wavelengths, a wavelength control part for switching the wavelength of the pulsed light, a probe for receiving an acoustic wave generated and spread within the test object irradiated with the pulsed light, a scanning control part for moving the probe in a predetermined scan field, and an information processing part for searching the test object information using a plurality of electric signals corresponding to the pulsed light of the plurality of the wavelengths outputted from the probe in each of the receiving position of the scan fields, wherein the wavelength control part switches the wavelength of the pulsed light before the probe scans the whole scan field while receiving the acoustic signal, in each of the receiving positions, corresponding to the pulsed light of at least one of the wavelength among a plurality of the wavelength. <P>COPYRIGHT: (C)2013,JPO&INPIT |
