Retina recognition is a biometric technique that uses the unique patterns on a person’s retina for person identification. The retina is the layer of blood vessels situated at the back of an eye. The eye is positioned in front of the system at a capture distance ranging from 8 cm to one meter. The person must look at a series of markers, viewed through the eyepiece, and line them up. The eye is optically focused for the scanner to capture the retina pattern. The retina is scanned with the near infrared (NIR 890 nm) irradiation and the unique pattern of the blood vessels is captured. Retina recognition makes use of the individuality of the patterns of the blood vessels. It has been developed commercially since the mid-1970s. Sandia Laboratory reported a false rejection rate of lower than 1.0%.
The idea for retinal identification was first conceived by Dr. Carleton Simon and Dr....
