So liquid crystal grating is used in extensive field such as diffraction optics, photoelectric switch, deflexion controlling of light beam.
因此液晶光栅的这种光电特性在衍射光学、光电开关、光束偏转控制等许多领域具有广泛的应用前景。
This paper puts forward a conception of a non-diffraction structured light (NDSL), which has characteristics such as linear structure, long focal-depth and narrow line-width, etc.
提出了一种无衍射结构光概念，这种光具有线性结构、焦深长、线宽小等特点。
Diffraction: When light rays pass close to opaque surfaces, such as the blades of a lens diaphragm , they are scattered;
衍射：当光束靠近经过不透明表面，如镜头光圈的叶片时，它会散开。
