Describe the mechanics of a retinal scan.
What will be an ideal response?
A retinal scan is performed by casting an undetectable ray of low-energy infrared light into a person's eye as she looks through the scanner's eyepiece. This beam of light outlines a circular path on the retina. Because retinal blood vessels are more sensitive to light than the rest of the eye, the amount of reflection fluctuates. The results of the scan are converted to computer code and stored in a database.
