Optical Experiment Simulations With Matlab

In recent days, optical experiment simulations, as a novel alternative method different from theroy and experiment to explore new things, are attracting more and more attention from both scientists and teachers. Based on many simulative experiments, we present the optical simulative algorithm and results by using Matlab program and give an introduction to all the results from the simulations. The main work is as follows:(1)First, simulations of optical interference are presented. Two spherical waves and multiple spherical waves interference, and Yang's interference experiments are simulated by using different methods. Two spherical waves interference is focused on the on-plane or out-plane of the spot light source plane and the observing plane. Then, we analyze how the temporal coherence of optical waves influence the contrast of the interference pattern. Furthermore, equal intense and unequal intense spherical waves interferences are investigated. Finally, Yang's double slits and circle apertures simulative results are detailedly presented.(2) Second, simulations of optical diffraction are presented. The Fresnel and Franhufer diffraction patterns, of regular shapes screen such as slits, rectangular apertures, circle apertures, discs, triangle apertures, Ronchi gratings, and some irregular shapes screen, are observed in the different propagation distance. This clearly gives the relation and difference of the two diffraction patterns.(3) Third, optical aberrations are simulated. Based on phase-intensity transform principle, the simulation results of Seidel aberration and Zernike polynomial are provided. According to the Kingslak's theory, the typical double beams interference patterns influenced by the aberrations are further analyzed.(4) Forth, simulations of 4/ optical system are presented. The optical information processing such as griddle filter and image plus&substract are realized by using the system.(5) Finally, a soft is programmed for the simulation of the optical experiment. It consists of all the above simulative programs, and dose not depend on the environment of Matlab or Visual C++. Based on the Matcom4.5, the m-files of Matlab are translated into C++ codes, then a suitable application program interface are designed by using Visual C++.
