| Abstract: | A new technique has been devised for coding and analysing moiré contours. It uses a video frame store in place of the more usual photographic reference grid, and a small microcomputer to automate fringe detection. The system is based on using a television camera to view a sample, the complete technique being developed primarily as an industrial tool for quality control, or as feedback sensor in flexible manufacturing. |
