衍射法测量细丝直径的研究
A Study on the Measurement of Filament by Diffraction Method
【摘要】 就几种影响因素从理论和实验上对激光衍射法测量细丝直径进行了研究 ,结果表明利用简单测量装置和采用一些简单的数字信号处理技术后 ,即可对 5 0~ 12 0 μm范围的细丝直径进行较高精度的测量 ,达到 1%的重复性精度
【Abstract】 Sources of error in a measurement of a filament diameter by laser diffraction method are studied theoretically and experimentally. Results demonstrate that the measurement can achieve 1% repeatability for thin wire diameter, which ranges from 50 to 20 μm, using the simpler apparatus of He Ne laser and the digital signal processing.
