Abstract

An apparatus for sensing and analyzing the reflectivity of at least a portion of the surface of an object (11), comprising: a light source whose output is directed toward that portion of the surface of the object, said light source comprising an array containing a plurality of switchable light generating units (30), each of said switchable light generating units emitting light within an individual selected waveband, said array collectively generating light containing a plurality of individual wavebands; sensing means (18, 20) to sense the light reflected from that portion of the surface of the object; and analysis means (computer system) receiving the input from said sensing means, to analyze the reflected light; wherein each said switchable light generating units inherently emits light within a single, narrow, fixed waveband, and wherein said array collectively generates light containing a plurality of individual fixed wavebands.
