A portable, hand held iris imaging system captures iris images that may be used in biometric identification. The system includes an illumination source for illuminating a subject's eye and a camera to capture light reflected from the subject's eye. An optical element positioned between the illumination source and the camera focuses light reflected from the subject's eye onto the camera. A controller receives the captured image and provides it to a display. If the system is not correctly positioned for iris image capture, the display may also provide visual feedback regarding how the system can be properly repositioned. The system includes a housing with a portable form factor so that it may be easily operated. |
