The method is based on measuring the deflection of rays from a collimated light beam due to gra***nts in refractive index.
平行光通过折射率存在梯度的场,光线产生偏转,即产生云纹效应。
Another important application of diffraction theory is the study of the far field divergence Angle of a collimated light beam.
衍射理论的另一个重要应用就是研究准直光束的远场发散角。
New technique of measuring 3d displacement field of object's surface by multiple overlapping holography to use collimated light beams is investigated.
本文研究用平行光多重全息术分析测量物体表面三维位移场的新技术。
On the basis of theories of physics, geometrical optics and photometry, the optical properties of collimated light beam incident upon single fiber perpendicular to the fiber axis are stu***d.
结合物理学的基本原理和几何光学的基本规律以及光度学的基础理论等三方面,研究了单纤维在平行均匀光束垂轴入射时的光学性质。
In contrast, the light from non-laser light sources cannot be collimated by optics as well.
相反,从非激光平行光源发出的光就不能被光学所瞄准。
|directional light;准直光束;平行光
“Collimated light”指准直光或平行光,即光线以几乎平行的方式传播,发散度极低的光束。以下是详细解释:
基本定义
Collimated light是由一组传播方向高度一致的光线组成的光束,发散角度极小,可近似视为平行光。例如,激光器发出的光或通过抛物面反射镜调整后的光(如探照灯)。
物理特性
如需进一步了解相关技术或具体案例,可参考光学专业文献或词典释义来源。
该单词是由两个词组合而成,其中“collimated”表示“准直的”或“聚光的”,“light”表示“光”。
“collimated light”指的是经过准直或聚光的光线。该术语通常用于描述光学元件的特性,如激光器、投影仪、显微镜等。通过使用准直器或聚光器,可以使光线变得更加直线或更加集中,从而提高光的质量和功率。
