您要查找的是不是：
- 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。
- When frequency is 301p/mm, the modulation transfer function(MTF) is near diffractive limit under 0.5 field angle, the modulation transfer function (MTF) is near 0.7 in edge field. 频率为301p/mm时系统的光学传递函数在0.;5°视场角以下接近衍射极限;边视场角的传递函数系数接近0
- In this paper, the research on vignetting is done and a formula for vignetting about field angle、entrance window, entrance pupil and the distance between them is deduced. 文中对渐晕做了一些研究，并推导出一个渐晕关于视场角、入瞳、入射窗以及两者之间距离的解析式。
- Within subtopics you will find bibliographic references for each book/article. 在这些小主题中，你可以找到每本参考书目和论文的详细出处资料。
- The method has not the effect of alignment error as the conventional ways to fabricate binary optics elements (BOB), and can avoid the defects with large field angle imaging in gray-scale mask technology. 该方法不存在传统的对准套刻法的对准误差影响，也避免了灰度掩模技术对大视场成像要求高的缺点。
- As for axial refractive index distribution, the error varies directly with viewing field angle and increases with the range of refractive index, but does not vary with object distance. 对于轴向折射率分布，其偏差与视场角成线性关系，随折射率变化幅度的增大而增大，但不随物距变化；
- As the field angles are different between direction of flight and its perpendicularity,the baffle is made non-symmetrical,so the ratio of block may below 1/3.3. 由于飞行方向与垂直方向视角不同;主镜上遮光筒和次镜上遮光罩的形状可以设计成非轴对称形状;并可使系统线遮栏比降为1/3.;3;
