PROBLEM TO BE SOLVED: To provide an illumination imaging device, even when a pupil is contracted or even when an eye is focused on a point adjacent to an imaging camera, capable of acquiring a pupil image with a prescribed luminance or more by performing illumination and imaging.SOLUTION: A polarizer 14 and a wavelength plate 15 as grid deflection elements are provided at an intersection between an optical axis 11C of a light source 11 for exiting detection light and an optical axis 12C of an imaging member 12. Light emitted from the light source 11 is reflected by the polarizer 14 and passes through the wavelength plate 15 to be applied to an object. The optical axis 11C of the light source 11 is made to match the optical axis 12C of the imaging member 12 so as to clearly acquire a bright pupil image by the imaging member 12.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】瞳孔が収縮している場合や目が撮像カメラの近傍に焦点を合わせている場合であっても一定以上の輝度の瞳孔画像を得ることができるように照明と撮像を行うことが可能な照明撮像装置を提供する。【解決手段】検知光を出射する光源11の光軸11Cと、撮像部材12の光軸12Cとの交差部に、グリッド偏向素子である偏光板14と波長板15が設けられている。光源11から発せられた光は偏光板14で反射され、波長板15を透過して対象物に与えられる。光源11の光軸11Cを撮像部材12の光軸12Cに一致させることで、撮像部材12で明瞳孔画像を鮮明に取得できるようになる。【選択図】図1
