Similar considerations apply to the diffracted rays . 對衍射光線可采用同樣的論證。
However , if the plane of the selector aperture is not precisely coplanar with that of the first image , then diffracted rays originating from outside the area defined by the aperture may contribute to the diffraction pattern 然而,如果選擇孔的平面與第一次成像不是正好共面,源自孔指定區域外部的衍射線可能影響衍射模型。
In considering diffraction errors there are two factors which will lead to diffracted rays originating from outside the area defined by the selector aperture , these are important in any work where a spatially accurate correlation of the diffraction data and the micrograph is required 考慮到衍射的差錯,有兩個因素決定源自選擇孔指定區域外部的衍射線,在任何工作中這些都是重要的,當衍射數據和顯微圖之間準確的空間對射被要求時。
