scanning slit

基本解释

The slit scanning is required to obtain two-dimensional spectral imaging.
爲了得到像斑的二維光譜，需要做狹縫掃描。
It consists of a magnetic scanning system, a thick slit, a fluorescent screen and a CCD image processing system.
它包括有磁掃描系統，厚窄縫，熒光屏以及CCD圖像処理系統。
In the focusing and imaging process of the GSJ model scanning camera, a light aperture is usually used as an imaging slit and then replaced by a graticule in situ.
在GSJ型相機聚焦成像過程中，通常先用光孔對象，然後再放上分劃板照像。
