PROBLEM TO BE SOLVED: To provide an optical imaging device for visualizing a depth part of a scatterer.SOLUTION: Among signals obtained by using an optical system similar to an optical coherence tomography, signals caused by a surface reflection light and scattering light for one time on a surface layer of an object to test are removed, and signals caused by multiple scattered light are extracted and imaged.COPYRIGHT: (C)2012,JPO&INPIT【課題】散乱体の深部を可視化する光イメージング装置を提供する。【解決手段】光コヒーレンストモグラフィと同様な光学系を用いて得た信号のうち、検査対象の表面反射光及び表層の一回散乱光に起因する信号を取り除き、多重散乱光に起因する信号を抽出し、画像化する。【選択図】図1
