DISCUSSION ON THE METHOD OF SOLUTION TO MULTI-BEAM SUPERPOSITION INTENSITY IN PHYSICAL OPTICS
In university physical optics,how to solve the problem of the superposition intensi-ty of multi-beam occupies a large proportion of the course content,which covers the superpo-sition principle,interference,diffraction,complementary screen principle,complex ampli-tude,conjugate wave and polarization.In order to enable the students of engineering colleges and universities without optical characteristics to solve the problem of multi beam superposi-tion intensity within a limited course learning period conveniently,and analyze the principle of actual interferometer equipment effectively,a set of programmed"six-step solution method to superposition intensity"was summarized.The method is fully explained by taking Young's experiment,single square hole Fraunhofer diffraction,the Babinet complementary screen sys-tem and a complex exercise as examples.Conclusion is the set of programmed method has good universality.
