Paper Abstract

The feasibility of using diffraction pattern analysis for the quality assessment of small components, with a specific application aimed at electronic components, is discussed. An electro-optical system for the capture of reflected diffraction patterns is presented. Preliminary simulation results for simple faults have been obtained and are used to illustrate the described feature vector and neural network classifier.
