ABSTRACT:
A system and method of positioning a head of a subject to be photographed by a single camera uses a mirror and at least one collimated light beam. The single camera is positioned so that there is a selected specific location in space within a field of view of the camera at which the head or eye of the subject is desired to be positioned. A light source directs a collimated light beam or light sheet so that the light beam or light sheet intersects a line running from the mirror through the selected specific location in space and can be seen by an eye at the selected specific location in space that is looking at the mirror. The user is told to position his head across from the mirror and move his head until he sees the collimated light beam or light sheet and his eye in the mirror. When the subject is so positioned the single camera can take an image of the eye from which the subject can be identified. If desired a second mirror can be used in place of the light source.
