PROBLEM TO BE SOLVED: To highly accurately generate biological information related to blood flow of an artery.SOLUTION: A detection device generates a first detection signal and a second detection signal used for identification of biological information related to blood flow of a measuring site, and comprises: a light emission section emitting coherent light； a first light reception section generating the first detection signal according to a light reception level of the coherent light being emitted from the light emission section and passing through an artery of the measuring site； and a second light reception section generating the second detection signal according to a light reception level of the coherent light being emitted from the light emission section and passing through the artery. The light emission section, the first light reception section and the second light reception section are installed on a detection surface facing the measuring site, and are positioned on a straight line. The first light reception section and the second light reception section are positioned at an equal distance from the light emission section at opposite sides to each other with the light emission section interposed therebetween.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】動脈の血流に関する生体情報を高精度に生成する。【解決手段】測定部位の血流に関する生体情報の特定に使用される第１検出信号および第２検出信号を生成する検出装置であって、コヒーレント光を出射する発光部と、前記発光部から出射して前記測定部位の動脈を通過した前記コヒーレント光の受光レベルに応じた前記第１検出信号を生成する第１受光部と、前記発光部から出射して前記動脈を通過した前記コヒーレント光の受光レベルに応じた前記第２検出信号を生成する第２受光部とを具備し、前記発光部と前記第１受光部と前記第２受光部とは、前記測定部位に対向する検出面に設置されて直線上に位置し、前記第１受光部と前記第２受光部とは、前記発光部を挟んで相互に反対側において前記発光部から等距離に位置する検出装置。【選択図】図２
