We present a novel method to assess the fairness of class A surfaces. The fairness of class A surfaces are often assessed by reflection curves on the surfaces of a family of parallel straight fluorescent lights, namely reflection lines and highlight lines. Unlike reflection lines and highlight lines, where a family of parallel straight lines are used for the light sources, we propose to use concentric circles as light sources. In this way we can capture the surface fairness in all directions, whereas the conventional methods can capture the fairness only in one direction. Illustrative examples show substantial merits of this method over the conventional straight line light based surface interrogation methods.
