OBJECT INFORMATION ACQUIRING APPARATUS AND CONTROL METHOD FOR OBJECT INFORMATION ACQUIRING APPARATUS

摘要

An object information acquiring apparatus includes: an acoustic wave generating member which absorbs light and generates an acoustic wave; an irradiating unit which irradiates an object or the acoustic wave generating member with light; a detector which detects an acoustic wave propagating from the object; a signal processing unit which generates object information that is information of the inside of the object, based on a signal output from the detector; and a switching unit which performs switching between a first mode in which a first acoustic wave generated inside the object due to irradiation of the light is detected by the detector and a second mode in which a second acoustic wave generated by the acoustic wave generating member due to irradiation of the light and having propagated inside the object is detected by the detector.
