| Abstract: | With high precision linear CCD as measuring sensor and combining with a mechanical scanning method,a quick measurement for the aperture of wire drawing die is carried out by the parallel light projection method.A circuit design with the ability of anti macula interference in testing aperture with CCD is proposed and the intrument accuracy is improved by correcting errors with computer. |
