Use A Retina Scanner For Security
A Biometric Eye Scanner uses a retinal scan of the eye to identify a person. The retina of the eye of each person is unique, just like a fingerprint. The retina of the eye is the thin layer of cells at the back of the eyeball where light is converted into neural signals which are then sent to the brain. It is connected to the optical nerve. The retina is covered with blood vessels and can be viewed using an ophthalmoscope. When viewed, it looks like an aerial view of a map with lots of roads and rivers (the blood vessels). Each person’s “map” is unique and can be used to identify a person’s identity. In most people, the retinal map is fixed at birth and doesn’t change throughout a person’s life. This makes it an excellent identification tool. It is used for security purposes such as a retina scan door lock.
Biometric Eye Scanner of the Retina
A retinal scan is performed by casting an invisible beam of low-energy infrared light into a person’s eye as they look through the scanner's eyepiece. This beam of light traces a standardized path on the retina. Because retinal blood vessels are more absorbent of this light than the rest of the eye, the amount of reflection varies during the scan. These patterns of variations are converted to a scanned image and stored in a database for future comparisons.
