Abstract
A rapid iris acquisition, tracking, and imaging system can be used at longer standoff distances and over larger capture volumes, without the active cooperation of subjects. The captured iris images can be used for biometric identification. Light illuminates the subjects' eyes. Eye reflection from the eyes is used to steer a high resolution camera to the eyes in order to capture images of the irises.
