Abstract

This application relates to systems and methods for imaging the iris of an individual. The iris images may be taken with an off-axis imager attached to a head-mounted system such as a pair of eyeglasses. In some instances, the iris images may be used for biometric recognition and identification.

Claims

1. A system for imaging the iris comprising an optical device and an off-axis imager attached to the optical device, wherein the off-axis imager comprises a lens and a camera body.

2. The system of claim 1, wherein the optical device comprises a head-mounted device.

3. The system of claim 2, wherein the head-mounted device comprises a pair of eyeglasses or goggles.

4. The system of claim 3, wherein the head-mounted device comprises a pair of eyeglasses, the pair of eyeglasses comprising a frame having an upper rim and a lower rim, and a transparent display.

5. The system of claim 1, wherein the optical device comprises an eyepiece.

6. The system of claim 5, wherein the eyepiece is a monocle or binoculars.

7. The system of claim 5, wherein the eyepiece is contained within a telescope, microscope, or a compound optical system used for viewing.

8. The system of claim 4, wherein the off-axis imager is attached to the lower rim of the frame.

9. The system of claim 1, wherein the lens of the off-axis imager has a tilt ranging from about 2.0 to about 8.5 degrees.

10. The system of claim 1, wherein the lens of the off-axis imager has a shift offset ranging from about 1.0 to about 2.5 mm.

11. A method for imaging an iris comprising providing an optical device having an off-axis imager attached thereto and imaging an iris of an individual using the off-axis imager, wherein the off-axis imager comprises a lens and a camera body.

12. The method of claim 11, further comprising obtaining biometric information from the imaged iris and processing the biometric information to verify the identity of the individual.

13. The method of claim 12, wherein the biometric information is converted into an iris code.

14. The method of claim 11, further comprising tilting the lens of the off-axis imager to adjust a focal plane of the camera body to be parallel with a plane of the individual'"'"'s iris.

15. The method of claim 14, wherein the lens is tilted between about 2.0 to about 8.5 degrees.

16. The method of claim 15, further comprising shifting the lens of the off-axis imager between about 1.0 to about 2.5 mm.

17. The method of claim 11, wherein imaging the iris comprises partially or entirely imaging the iris of the individual.

18. The method of claim 11, wherein one or both irises of the individual are partially or entirely imaged.
