ABSTRACT:
A transportable apparatus for evaluating a reflective object comprises a main body portion and a plurality of elongated light sources attached to the main body portion. The elongated light sources are adapted to produce images in the reflective object which will visually reveal flaws in the surface of the reflective object through portions of discontinuous curvature. The apparatus can be easily transported to various positions about the reflective object, thereby facilitating evaluation of a variety of differently oriented portions of the object.
