PROBLEM TO BE SOLVED: To provide an eyeball imaging apparatus capable of capturing an image of an eyeball, with no light source reflected on the surface thereof.SOLUTION: The eyeball imaging apparatus comprises a light source 31 for applying illumination light of infrared light. The illumination light from the light source 31 passes through an illumination polarizer 32 and enters the eyeball. Image light from the eyeball passes through an imaging polarizer 33, the polarizing direction of which orthogonally crosses with that of the illumination polarizer 32. Then, surface reflection light generated on the surface of the eye ball is cut off and only internal reflection light passes through the imaging polarizer 33. The image light passing through a lens 11 and imaged by an imaging device 12 does not include the surface reflection light, so that the light source 31 is not reflected in an image of the eyeball. The illumination polarizer 32 and the imaging polarizer 33 are a wire grid polarizer that functions as a polarizer for light in the infrared range.COPYRIGHT: (C)2014,JPO&INPIT【課題】光源がその表面に写り込んでいない状態で眼球の撮像を行える眼球撮像装置を提供する。【解決手段】眼球撮像装置は、赤外線である照明光を照射する光源31を持つ。光源31からの照明光は照明用偏光板32を通過して眼球に至る。眼球からの像光は、照明用偏光板32と偏光方向が直交する撮像用偏光板33を通過する。このとき眼球の表面で生じた表面反射光は遮断され、内部反射光のみが撮像用偏光板33を通過する。レンズ11を経て撮像素子12で撮像される像光は表面反射光を含まないので、眼球の画像には光源31が写り込まない。照明用偏光板32と撮像用偏光板33は赤外領域の光に対して偏光板として機能するワイヤグリッド偏光板である。【選択図】図2
