ABSTRACT:
A non-contacting deviation measurement system projects a first line and a second line upon a surface of an object. The projections of the first line and second line are arranged to overlap at an intersection line oriented at a nominal location such that when the surface is oriented at the nominal location, the intersection line appears on the surface. As the location of the surface deviates from the nominal location, the first line and second line as projected upon the surface move away from one another. The distance between the lines may be used to calculate the deviation from the nominal location. The deviation calculated may be compared to a predetermined maximum allowable deviation.
