摘要：An object information acquisition apparatus according to an embodiment of thepresent invention includes a plurality of transducer elements each configured to transmit

an acoustic wave to an object, to receive reflected waves reflected from inside the object,and to convert the reflected waves into a time-series reception signal; and a processorconfigured to perform frequency domain interferometry combined with adaptive signalprocessing by using the reception signals output from the plurality of transducerelements and a reference signal so as to obtain acoustic characteristics at a plurality ofpositions located inside the object. The processor is configured to switch the referencesignal to another reference signal at least once in accordance with a target positionlocated inside the object while performing the frequency domain interferometry so as toobtain the acoustic characteristics at the plurality of positions located inside the object.
