摘　　要：大学物理光学中多光束相遇叠加强度的求解问题占据了课程内容的很大比重,涵盖了叠加原理、干涉、衍射、互补屏原理、复振幅、共轭波和偏振等理论和概念。为了使非光学特色工科大专院校的学生在有限的课程学习期间内快速方便地解决多光束叠加强度求解问题,有效地对实际的干涉测量设备原理进行分析,总结了一套“叠加强度求解六步法”的程序化解题流程,通过杨氏实验、单矩形孔夫琅禾费衍射、巴比涅互补屏系统和一个复杂习题解答为例对该方法的使用进行了充分举例说明,有效地论证了该方法的有效性和通用性。In university physical optics,how to solve the problem of the superposition intensity of multi-beam occupies a large proportion of the course content,which covers the superposition principle,interference,diffraction,complementary screen principle,complex amplitude,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 superposition 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 system and a complex exercise as examples.Conclusion is the set of programmed method has good universality.
