Abstract
A personal identification apparatus for providing information characteristic of an eye includes a housing with an entrance window through which a user looks at a target object. An image capture device within the housing operates to provide an image signed representing features of the eye and responsive to non-visible light reflected from the eye. In addition to the illumination source for the non-visible light reflected from the eye the apparatus also includes an optical element substantially transparent to the non-visible light and which has a first region less transparent to visible light from the target object than a second region. The arrangement of the apparatus is such that the image capture device views the eye through the second region of the optical element and the eye views the target object through the first region of the optical element.
