1. A method for carrying out non-coplanar 3-D measurements of surface points, comprising the steps of:

  • forming light from a light source into a plane of light;

    reshaping said plane of light into a non-planar beam;

    projecting from a projection source said non-planar beam upon a surface to be measured and forming an intersection of said beam with said surface;

    imaging at an imaging site light reflected from said intersection from an angle different than said projected beam; and

    generating coordinates of said surface intersection points illuminated by said projected beam based on a known angle of projection, known angle of imaging and distance between projection source and imaging site.
