ABSTRACT:
A system for identification comprising: a surface (14) comprising retro-reflective indicta; a source of light that illuminates the indicta (18) along an illumination direction; and a detector (20, 21) that views light reflected from the indicta, wherein the retro-reflector reflects the light that illuminates it as a plurality of beams at a plurality of angles relative to the illumination direction.
