Abstract: A system and method for obtaining biometric imagery such as iris imagery from large capture volumes is disclosed wherein a substantially rotationally symmetric mirror such as a cone or sphere is rotated at a constant velocity about a central axis.

Abstract: A primarily hand-held or adjustable-mount iris recognition device wherein feedback to the operator is provided by visible illumination or imagery projected onto the face of the subject, as well as an audio signal, while infra-red illumination is projected onto the face of the subject as an illumination source for an iris recognition process. When the device is pointed in the direction of the subject, the infra-red illumination is directed to illuminate primarily the eye region whereas the visible illumination is directed to illuminate primarily other regions including the cheeks. The visible illumination is configured such that the position of the visible illumination on the face indicates to the operator whether the iris recognition device is pointed in the correct direction and at the correct distance for optimal iris recognition.

Abstract: Apparatus and methods for determining whether a live, human eye is presented for iris-based recognition. An image is presented on a computer screen and reflected back from the eye. The reflected image is captured and processed to determine whether the reflection was consistent with a human eye.
