衍射(英语:diffraction)是指波遇到障碍物时偏离原来直线传播的物理现象。光在传播路径中,遇到不透明或透明的障碍物或者小孔(窄缝),绕过障碍物,产生偏离直线传播的现象称为光的衍射。衍射时产生的明暗条纹或光环,叫衍射图样。包括:单缝衍射、圆孔衍射、圆板衍射及泊松亮斑。 衍射条纹是指光的衍射投射在屏幕上的条纹。
改变表面波振幅,发现了各级衍射条纹的强度变化。
The diffraction intensity is variable with the surface wave amplitude which was also found.
本文就是介绍一种简单的方法,把干涉条纹和衍射条纹分开。
This paper introduce an easy way in which the interference fringes and the diffraction fringes can be separated.
科研人员是如何做到这一切的呢?他们利用衍射条纹来产生一个物体的3d轮廓。
The researchers managed all this by tapping what are known as diffraction fringes to create an object's 3-d shape.
