- A special array of light pipes was constructed and used with a photodetector to measure the angular distribution of light reflected diffusely from small isolated defects on superfinished nickel spheres. Defects in a size range of concern were detected by the system, and angular distributions of the diffuse light generated by the defects correlated with the defect dimensions. At present, a commercial version of the light sensing array used in this study is not available; however, under development is a more desirable optical system for automated surface certification which will use a photodetector array which is available commercially.
