Computer Analog Simulation and Expression Inference Fraunhofer's Multiple-slit Diffraction

Fraunhofer's multiple-slit diffraction results from the multi-beam interference of single-slit diffraction modulation,which is an important theory of wave optics.On the basis of experimental observations,studies from multiple-slit to single-slit diffraction as well as related theory,the paper aims to validate Fraunhofer's simulations of multiple-slit diffraction through the adoption of optics distribution formula of multi-beam interference and single-slit diffraction and also inspire teaching and experiment.Above is to ideal type of periodic grating research.
