PROBLEM TO BE SOLVED: To solve such a problem that, if light emission frequency is increased for shortening an acquisition time of a reception signal, SNR is reduced since an exposure amount has to be reduced.SOLUTION: An analyte information acquisition device of the present invention comprises: a probe comprising a receiver for receiving an acoustic wave and then converting the wave into an electric signal, and a first radiation part and a second radiation part for respectively radiating pulse light to different areas on an analyte surface； and a controller for controlling radiation positions of the pulse light so that the pulse light is not radiated continuously to the analyte from the respective first and second radiation parts.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】 受信信号の取得時間を短くするために発光周波数を上げると露光量を下げる必要があるためＳＮＲが低下する。【解決手段】 本発明の被検体情報取得装置は、音響波を受信し電気信号に変換する受信器とパルス光を被検体表面の夫々異なる領域に照射するための第一の照射部及び第二の照射部とを有するプローブと、前記第一及び第二の照射部の夫々から前記被検体に連続してパルス光が照射されないようパルス光の照射位置を制御する制御部を有する。【選択図】 図２
