Claim One:
1. Apparatus for identifying individuals through the ocular light reflection pattern from the fundus of the eye, comprising: (a) fixation means providing a fixation beam of visible light for positioning and focusing the eye of an individual along its visual axis, said axis being centered on the fovea, (b) source means providing a source beam of infrared radiation, (c) scanner means positioned for receiving the source beam and for directing it into the fixated eye from a plurality of sequential angularly divergent positions, in order to form a substantially circular locus of points substantially centered on the fovea, the source beam being directed along the visual axis into the scanner means, the scanner means comprising a housing rotatable about the visual axis, a first mirror mounted in the housing for reflecting the source beam of axis, and a second mirror mounted in the housing at a point spaced from the axis and oriented to direct the source beam into the eye as the housing rotates, and (d) receiver means positioned for detecting the intensity of the light radiation reflected from the eye at each sequential location.
