SPECIMEN INFORMATION ACQUISITION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a technique for enabling photoacoustic imaging at a resolution equal to or smaller than the wavelength of light.SOLUTION: A specimen information acquiring apparatus is used which includes: a first light source outputting irradiation light delivered to a specimen; an output unit to which the irradiation light is guided and which includes an opening smaller than a wavelength of the irradiation light; a probe detecting an acoustic wave generated when the specimen absorbs near-field light output by the output unit; and a signal processing unit acquiring information on the interior of the specimen from the acoustic wave detected by the probe.
