PROBLEM TO BE SOLVED: To provide a measuring device of the inside of a scatterer for easily and quickly obtaining information on a measurement target present in the scatterer, and to provide a measurement method using the measuring device.SOLUTION: The measuring device of the inside of a scatterer for acquiring information on the measurement target in the scatterer includes an illumination means for applying light having different optical characteristics between the measurement target and the scatterer to the scatterer, a detection means for detecting the backscattering light of light applied by the illumination means as a two-dimensional image, and an analysis means for confirming the presence or absence of the measurement target in two-dimensional image data obtained by the detection means for obtaining position information including the depth of the measurement target in the scatterer from the distance between the illumination position on the two-dimensional image and a position where the measurement target has been confirmed. The measuring device of the inside of the scatterer performs measurement while the illumination means and the detection means are not in contact with the scatterer.COPYRIGHT: (C)2010,JPO&INPIT【課題】散乱体の内部に存在する測定対象の情報を、簡便且つ短時間で取得できる散乱体内部計測装置及び該装置を用いた計測方法を提供することを目的とする。【解決手段】散乱体内部の測定対象の情報を取得する散乱体内部計測装置であって、前記測定対象と前記散乱体とで光学特性の異なる光を前記散乱体に照射する照明手段と、前記照明手段により照射された光の後方散乱光を2次元画像として検出する検出手段と、前記検出手段により取得された2次元画像データにおいて前記測定対象の存在の有無を確認し、前記2次元画像上における前記照射位置と前記測定対象が確認された位置との距離から、前記散乱体における前記測定対象の深度を含めた位置情報を求める解析手段とを備え、前記照明手段と前記検出手段が前記散乱体に非接触で計測が行われることを特徴とする散乱体内部計測装置を提供する。【選択図】 図1
