field angle meaning in English
波束角
视场角
张角或光束角
Examples
- Design of scene simulation optics for dual field angle infrared imagers
直接探测多普勒激光雷达的光束扫描和风场测量 - This star is at the zero field angle and , as in our example above , we are enjoying a diffraction limited view of this star
这颗星的角度就是0度，我们当然很乐意进行这样的单星测试。 - Especially , analyze qualitatively the effect that the cathode magnetic field angle contributes to beam ratio and prove it by calculation
特别的是,文章中定性分析了阴极磁场角对电子注速度比的影响,并通过计算获得证明。 - Liquid crystal tunable filters as an important device of wavelength division multiplexing and dense wavelength division multiplexing systems is caused attention by research department , especially many foreign research institute are studying it . but in our country its study is lag . and normal incidence of the crystal is almost the case , because the liquid crystal box is very thin , the field angle may be large and the pose of liquid crystal box may have impact on the measuring result . so , study in such subject , especially the liquid crystal box ' s position angle , is academic and valuable
各种改进液晶电光可调谐滤光片的措施的实现，使得液晶调谐滤光片成为一种很有应用前景的电光调谐滤光片，特别是用于光纤通信中的波分复用系统和密集波分复用系统，将使光纤的传输客量大大增加目前国外在这方面的研究进展很快，而国内在这方面的研究比较薄弱，而且通常采用光线正人射晶体进行研究，由于液晶盒很薄，视场角可以很大，液晶盒的摆放对测量结果影响很大，因此对该器件进行深入的研究，讨论液晶盒的方位角影响是很有必要的。
