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.
Claims47
An iris imaging system comprising an imaging subsystem, the imaging subsystem comprising:
- a camera for capturing images of irises with sufficient resolution for biometric identification;
- a light source for producing light to illuminate eyes;
- and
- a fine tracking system for steering the camera to eyes, based on an eye reflection of the light illuminating the eyes.
1 more element

- illuminating the eye with light;
- steering a camera to the eye based on an eye reflection from the eyes of the illuminating light;
- and
- the camera capturing an image of the iris with sufficient resolution for biometric identification.
