PROBLEM TO BE SOLVED: To improve accuracy of information acquisition in an apparatus that irradiates a subject with light of plural wavelengths to acquire information inside the subject.SOLUTION: The subject information acquiring apparatus comprises: an irradiation unit for emitting pulsed light of plural wavelengths different from each other； a receiving unit for receiving, per each of the plural wavelengths, subject signals propagating from the subject irradiated with the pulsed light and converting the received subject signals into plural reception signals； a correction unit for correcting at least any of the plural reception signals according to the pulse shape of each of the pulsed light with the plural wavelengths； and an information acquisition unit for acquiring spectroscopic information of the subject using the plural reception signals corrected by the correction unit.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】複数の波長の光を被検体に照射して被検体内部の情報を得る装置において、情報取得の精度を向上させる。【解決手段】互いに異なる複数の波長のパルス光を照射する照射部と、複数の波長のそれぞれについてパルス光を照射された被検体から伝搬する被検体信号を受信することにより、複数の受信信号に変換する受信部と、複数の波長のパルス光それぞれのパルス形状に応じて、複数の受信信号のうち、少なくともいずれかを補正する補正部と、補正部により補正された複数の受信信号を用いて、被検体の分光情報を取得する情報取得部を有する被検体情報取得装置を用いる。【選択図】図２
