Experiment and simulation study on poisson spot
摘要
Abstract
This paper is an attempt to achieve the accurate control of Poisson spot in the wave optics experiments.The study is focused on the effects of incident light wavelength,circular disk diameter and diffraction distance on the diameter and intensity of Poisson spot based on the experiments and simula-tions.The results show that the larger the diameter of the circular block,the smaller the diameter of the diffracted Poisson spot is;and as the wavelength of the incident light and the diffraction distance in-crease,the diameter of the diffracted Poisson spot also increases.The intensity of the Poisson spot is neg-atively correlated with the diameter of the circular disk and positively correlated with the diffraction dis-tance and the wavelength of the incident light within a certain range.As the diffraction distance or inci-dent light wavelength gradually increases,the increase in intensity of the Poisson spot decreases,and e-ven intensity fluctuations may occur.The smaller the diameter of the circular disk or the larger the wave-length of the incident light is,the shorter the diffraction distance deeded to form the Poisson spot is.关键词
