Paper Abstract

In this paper, development of a novel optical diameter gauge is described. In order to eliminate the influence of wire vibration in the high moving speed, the semiconductor laser diode with 1.2μs exposure time aperture were used to be the illuminating light soruces, a CCD-lien sensors wtih 5000 elements and 7μm*7μm element area were applied to guage the diameter of the object. Data acquistion unit consists of high speed A/D converter, single chip processor, DMA and SRAM to process the signal data digitally in order to gain the high accuracy. The instrument obtained 0.7μm on line dynamic accuracy finally.
