Systems and methods for illuminating an iris with visible light for biometric acquisition

摘要

The present disclosure is directed towards methods and systems for acquiring biometric information of an individual. The apparatus may include a light source directing visible light towards an eye. The light source may direct the visible light at an angle of at least 30 degrees from a line of sight of the eye. The visible light may penetrate a surface of the iris, illuminating substantially the whole iris for biometric acquisition. The visible light may have an intensity level above that which causes discomfort to the eye if the visible light reaches a light-sensitive part of the eye's retina. A sensor may acquire iris biometric data from the illuminated iris.

主权项

1. An apparatus for acquiring biometric information of an individual, the apparatus comprising:
a light source, directing a visible light beam towards an iris of an eye at a first angle that avoids a light-sensitive portion of the eye's retina, the visible light beam illuminating the iris for biometric acquisition and matching, the visible light beam having an incident intensity level that (i) would cause discomfort to the eye if directed at the light-sensitive portion of the retina, and(ii) is sufficient to illuminate striations of the iris for the biometric acquisition at a reflected intensity level that exceeds that of visible light reflected from the cornea due to other light sources; and a sensor, acquiring iris biometric data from the illuminated iris for the biometric matching.
