一种实用的光栅

A practical optical grating

光栅衍射实验中会出现缺级现象,但是利用普通光栅观察缺级现象时,得不到理想的光栅衍射的缺级条纹。为了解决这个问题,提出了一个切实有效的实验方法,利用羽毛做光栅获得了出乎意料的好效果。

There is a phenomen on of missing order in an optical grating diffraction experiment.Utilizing ordinary optical grating to observe the phenomena of missing order cannot obtain ideal missed stripes. In order to solve this problem, an experiment method is presented for utilizing a feather as an optical grating.The results are excellent.
