| Abstract: | The methods of the diameter measurement of filament have been summarized at first. The principle and experiment equipment of Fraunhofer Diffraction method have been presented. The error factors of Fraunhofer diffraction method have been analyzed systematically. The method of calibrating the working distance D has been presented. We have measured the diameters of four different filaments and verified the results obtained from Fraunhofer diffraction method by two other methods. |
