ABSTRACT:
An identifier which scans the retina of an eye, senses the magnitude of reflections and transmits signals representative of the magnitudes to a remote location which stores the signals and compares them to previously stored magnitude signals for purposes of identifying the eye and, hence, the owner of the eye. The equipment can alternatively be used to produce a direct written image on the retina. Combining the two provides a secure communication system.
