光栅衍射实验问题的分析及解决

Analysis and Solution of Problems in Grating Diffraction Experiment

通过分析光栅衍射的原理,明确满足光栅方程的实验条件,即光垂直入射到光栅。针对光栅衍射实验中光栅的调节、现象的观测及测量方法等问题,提出相应的解决方案,并从理论和实验两方面说明采取对称测量法的原因。

By analyzing the diffraction principle of the grating,the experimental condition satisfying the grating equation is defined,that is,the light is incident into the grating vertically.The corresponding solutions are put forward to solve the problems of grating adjustment,phenomenon observation and measurement in grating diffraction experiment.The reasons for adopting symmetrical measurement method are explained in combination with theory and experiment.
