  • Method and apparatus for illuminating and imaging eyes through eyeglasses using multiple sources of illumination
    Patent number: 6055322
    Abstract: A reliable method of illuminating and imaging an eye through eyeglasses uses a carefully selected subset of multiple monochromatic light sources, a camera with an imager that exhibits minimal blooming, and a narrow-bandwidth optical bandpass filter to filter out most of the ambient illumination while passing most of the light from the system's own illuminator.
