diffraction pattern：衍射图样

马克斯冯劳厄让一束X射线穿过一个晶体投射到一个照相底片上,在那上面会产生斑点图样. 这种衍射图样(diffraction pattern)因各种晶体类型的不同而不同. 人们运用数学方式对斑点的位置和黑暗程度进行分析,进而看出晶体的原子结构.

diffraction pattern：绕射图形

其利用电磁透镜(Electromagnetic Lens)来偏折、聚焦加速的电子,使电子撞击材料,产生穿透电子束与弹性散射电子束,而后这些电子束再经过电磁透镜放大、聚焦,最后形成影像(Image)或绕射图形(Diffraction Pattern).

diffraction pattern：衍射图

diffraction limit 衍射极限 | diffraction pattern 衍射图 | diffraction propagation 绕射传播

diffraction pattern：绕射图

diffraction grating 衍射光栅 | diffraction pattern 绕射图 | diffraction spot 衍射斑点
