摘要
讨论了夫琅禾费衍射实际实验中的反常现象,在一定条件下给出了计算机模拟的结果.实验表明,衍射图样的实验数据点分布结果与数值计算的模拟结果一致.由此可知,夫琅禾费衍射光强的反常分布是远场条件失效所致.
The abnormal phenomenon in the experiment of Fraunhofer diffraction was discussed, and the results of computer simulation in certain conditions were given. The experimental data of the diffraction matched the numerical calculation well, indicating that the abnormal light distribution of Fraunhofer diffraction was caused by failure of the near-field condition.
