摘　　要：分析了目前激光单缝衍射光强分布测量中存在的问题,给出了两点改进的测量方法:一点测量技术上的改进和一点实验仪器上的改进更新。用改进后的实验仪器较好地测量得到各级明条纹的光强分布。实验测量结果与夫琅和费衍射理论模拟结果吻合较好。This article analyses the present problems about measuring the light intensity distribution of single- slit laser diffraction by laser, two improved measuring method is presented： an improved method on measure- ment technology and a little updated improvement on the experimental apparatus. Get better bright streaks of light intensity distribution at various levels measured with the improved experimental apparatus. To a better ex- tent the experimental result tallies with the analog result of Fraunhofer diffraction theory.
