Abstract

Real-time, non-contact, high accuracy measurements of small components are realised utilizing diffraction pattern theory. High speed line-scan CCD (charge coupled device) sensors, coupled with a microcomputer system with specalised hardware, allow the implementation of least squares and transform algorithms for the analysis of diffraction pattern data.
