Moiré inspection of multicomponent assemblies
Abstract
This paper discusses the use of moire techniques to enhance optically the generation of binary images in automatic visual inspection systems. Techniques for enhancing the illumination of out-of-plane features or highlighting areas of missing or misaligned parts on an assembly were investigated. The applications of these techniques to a practical inspection problem were demonstrated.
