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 1 |
