摘要： A fundus imaging apparatus includes an illumination apparatus including a light source and an illumination optical system, and an imaging apparatus including an image sensor and an imaging optical system. The illumination optical system irradiates a fundus with light from the light source. The imaging optical system forms an image of the fundus on the image sensor. An optical axis of the illumination optical system does not match an optical axis of the imaging optical system, or the illumination optical system does not have a specific optical axis.

摘要： An optical system for observing reflected light from a fundus includes: an irradiation unit for irradiating an eye with light exited from a light source; a light-acceptance unit for accepting reflected light reflected on a fundus of the eye; and a polarization control unit for making light irradiated to the eye z-polarization axisymmetric with respect to an optical axis and blocking the z-polarization of reflected light reflected on the eye and directed to the light-acceptance unit.
