摘要

考虑了多源波场的近似描述问题。结果表明,如果综合考虑这个问题,干涉和衍射实验的描述可以在单一方案的框架内给出。结果表明,在这两个经典实验中,波的放大特性是不同的。在干涉实验中,场放大固定在某一点,而在衍射实验中,场放大固定在观测方向。研究了在夫琅和费衍射图中衍射光栅强度最大值满足的情况下,确定菲涅耳衍射图中衍射光栅强度最大值的问题。得到了衍射光栅像透镜一样工作的条件。

Description of the Classical Diffraction Experiment of a Systemof Many Slits and the Interference Pattern of Two Sources within the Framework of a Single Scheme
The problem of an approximate description of the wave field of many sources is considered. It is shown that, if the problem is considered more comprehensively, the description of the interference and diffraction experiments can be given within the framework of a single scheme. It is shown that the character of wave amplification in these two classical experiments is different. In the case of an interference experiment, the field amplification is fixed at a point, while in the case of a diffraction experiment the field amplification is fixed in the observation direction. The problem of determining the intensity maximum of a diffraction grating in the Fresnel pattern is studied under the condition that the maximum is satisfied in the Fraunhofer pattern. A condition under which a diffraction grating behaves like a lens is obtained.
