<P>PROBLEM TO BE SOLVED: To detect a photoacoustic wave higher in S/N in a photoacoustic inspection using a photoacoustic effect. <P>SOLUTION: A probe 70 used for a photoacoustic inspection includes a photoirradiation part 15 for irradiating a subject 7 with light L and an electroacoustic transformation part 3 for transforming the photoacoustic wave U into an electric signal. The photoirradiation part 15 irradiates an irradiation range on the subject 7 which encompasses all corresponding areas on the subject 7 corresponding to the electroacoustic transformation part 3 with light where a minimal outer circumferential end interval Wmin between an outer circumferential end Ea of the corresponding area and an outer peripheral end Eb of the irradiation range is 5 mm or wider. <P>COPYRIGHT: (C)2012,JPO&INPIT |
