Abstract
An iris recognition apparatus (12a) and method includes a camera (22) for imaging the human retina as seen through the pupil. The reflective retina and pupil are imaged as a luminous or retro-reflective spot located in a field of view (26). A direction to the spot (i.e., the retina spot at the pupil within the iris) in the field of view is determined, and a fine-focus video camera (48) is directed along this direction to capture an image of the iris surrounding the pupil of the eye. The captured iris image can be used for unique and individual identification of the human whose eye is imaged using known data storage, retrieval, and comparison methods.
