1. An apparatus for determining the coordinates of an object, comprising:

  • (a) a modulated light source having pixels whose light intensity may be individually modulated, wherein said light source is directed toward said object;

    (b) an image detector having a plurality of pixels for receiving light reflected from said object; and

    (c) means for determining the coordinates of points wherefrom pixels of light are reflected from the surface of said object, wherein the determination is responsive to the relative location and intensity of pixels registered on said imaging detector such that the relative intensities are mathematically correlated with the modulation of the light source to resolve the proportional loss of light intensity and the position of said pixels at said modulated light source and from which the location of the associated point of reflection may be determined by triangulation.
