Claim Text:
1. A system for measuring a deflection of an underlying surface, the system comprising: a base; a first laser affixed to said base, said first laser directed downwardly toward the underlying surface at an acute angle relative to said base; a second laser affixed to said base and positioned in spaced relationship and on one side of said first laser, said first laser directed downwardly in a direction toward said second laser, said second laser directed downwardly toward the underlying surface at an angle approximately transverse to said base; a third laser affixed to said base and positioned in spaced relation to said second laser on a side of said second laser opposite said first laser, said third laser directed downwardly toward underlying surface at the same acute angle relative to said base and in a direction toward said second laser; a camera directed downwardly toward the points of reflectance of said first laser and said second laser and said third laser with the underlying surface; and a processor cooperative with said camera so as to measure a distance between the point of reflectance of said first laser with the underlying surface and the point of reflectance of said second laser with respect to said underlying surface and so as to measure a distance between the point of reflectance of said second laser with the underlying surface and the point of reflectance of said third laser, said processor comparing the measured distances so as to produce an angle of deflection of the underlying surface.
