摘要
BPM（Beam－PropagationMethod）是标量亥姆霍兹方程的迭代解法，用它可计算光振福在光纤或波导中的分布。本文介绍了用BPM计算厚透镜的算法，并介绍了相于光学系统的计算机模拟算法，这对于相干光学系统的设计有着重要的意义．
BPM(Beam-Propagation Method) is an iterative solution of the scalar Helmholtz equation. It is used to calculate light amplitude distributions in fibers or waveguidesThis paper introduces the numrical algorithm that uses BPM to calculate thick lenses and simulates coherent optics system. It is important for the design of coherent optics system.
