摘　　要：光刻槽的补偿问题在激光雕刻中有着重要意义，以往的光刻槽补偿算法由于没有考虑到图形的拓扑特性，从而引入了拓扑噪音，使得输出分辨率降低。本文从数学形态学的理论出发，提出了一种同伦粗化的补偿算法，在实践中取得了良好效果。The compensative problem of laser trough is very important in laser carving.The old compensative algorithm brings the topological noise and decreases the output resolution because of not considering the image topological characteristic.This paper gives a compensative algorithm based on homologous thicking in mathematical morphology.The algorithm has proved to be well in practice.
