PROBLEM TO BE SOLVED: To provide an optical biological information measuring device which acquires biological internal information easily with high accuracy.SOLUTION: An optical biological information measuring device has: an optical system which localizes the inside of a living body from a surface of the living body and illuminates it and an image forming optical system 4 in which localized illumination lights intruding the inside of the living body repeat scattering in the living tissues and form images of an optical pattern emitted from the surface of the living body on a plurality of pixel arrays of a solid-state image pickup device 5 provided on the surface of the living body. The optical biological information measuring device acquires information about the inside of the living body on the basis of the optical pattern emitted by the surface of the living body picked up by the solid-state image pickup device. As the illumination optical system, wavelengths are changed by illumination lights having a plurality of center wavelengths to acquire information, the optical biological information measuring device is moved, and an internal structure of the living body is estimated on the basis of individual images.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】簡便に高精度で生体内部情報を取得する光学式生体情報測定装置を提供する。【解決手段】生体の表面より生体内部を局在化させて照明させる光学系と、生体内部に侵入した局在化した照明光が生体組織内部にて散乱を繰り返し、生体表面から出射される光学パターンを、生体表面上に設けられた固体撮像装置5の複数の画素配列に結像させるための結像光学系4を有し、固体撮像装置で撮像した生体表面から出射される光学パターンを基に、生体内部の情報を取得する光学式生体情報測定装置。照明光学系としては複数の中心波長を有する照明光で波長を変化させ情報を取得し、また光学式生体情報測定装置を移動させ、個々の画像を基に生体内部構造を推定する。【選択図】図1
