| Abstract: | The edge-points of a workpiece diameter may be located by imagingcylinder-edge diffraction. If a proper set-up for measuring length and a micro-computer are provided,then the on-line system for measuring workpiecediameter may be constituted.in the paper the theory for the location usingcylinder-edge diffraction is presented, the structure and the function of thestop in the light path are discussed,and the experimentla equipment formeasuring the diameter by the location using cylinder-edge diffraction is describe. |
