| 摘 要： | 本文通过单缝夫琅和弗衍射的光强分布实验，引伸出在远场接收的条件下，若屏距ｘ与单丝直径ｄ之比为定值，其标准光强分布就被唯一地确定．反之，当我们已知光强分布，就可以求出单丝直径．本文以“单维衍射的光强分布”实验为基础，引出连续测量细丝（如铜丝、尼龙丝等）直径的装置．

| Abstract: | Through the experiment of light intensity distribution of single slit Fraunhofer diffraction,this paper channels receiving conditions of far field,If the ratio between screen distance x and single slit diameter d is fixed value,its standard light intensity distribution is exclusively determined.If not,when we know light intensity distribution we will know x/d value. If screen distance x is measured,single slit diameter can then be solved. |
