摘要
本文针对摄影中出现的小孔衍射现象——'星芒',即以点状光源为中心呈均匀放射状的衍射条纹,采用Matlab软件模拟仿真衍射图样,并通过Matlab与Visual Studio 2013混合编程开发可视化应用程序进行探究。为验证仿真结果的准确性,本文将典型的衍射图样的理论计算值与程序模拟值进行比较,吻合程度较高,初步证明模拟仿真程序具有一定的可靠性。最后,本文利用模拟程序对由多边形孔产生的'星芒'线特征进行了探究,并得到了关于'星芒'线数量与分布特征的初步结论。
In this paper a photography diffraction phenomenon—'Diffraction Spike',a type of diffraction fringes radiated from point-source of light,was explored,The diffraction patterns were simulated with Matlab and developed interface with Visual Studio 2013.The theoretical calculated data of the typical diffraction pattern of the analog value are compared with the simulated ones to verify the accuracy of the simulation results.The results show that the theoretical value of the analog value is very consistent,proven simulation program with a certain reliability.Finally,the distribution feature of'Diffraction Spike'were explored using the simulation program and got preliminary conclusions.
