1. A combination remote retinal scan identifier and direct retinal scan display comprising:

  • a light source, including a laser, forming a directed beam of light;

    deflection means positioned to receive the beam of light for scanning the beam of light over at least a portion of a retina, the deflection means including reflecting surfaces moveably mounted to direct the light beam generally in two orthogonal directions;

    modulating means positioned to receive the directed light beam from the light source for modulating the light beam with video information prior to the deflection means receiving the light beam;

    electronic means coupled to the deflection means and the modulating means for controlling the deflection means and the modulating means to scan a video image on the retina;

    a detector positioned to receive reflected light from the scanned retina and provide output signals indicative of the magnitude of reflected light; and

    a communication transmitter coupled to the detector to receive the output signals from the detector and transmit the output signals to identification apparatus remote from the communication transmitter; and

    electronics coupled to the modulating means and the detector for activating the detector and deactivating the modulator means during remote retinal scan identifying and for deactivating the detector and activating the modulating means to produce a direct retinal scan display.
