您要查找的是不是：
- camera field angle 摄像机张角
- Does this extend to the edge of our eyepiece or camera field of view? 会延伸到目镜的边缘或者是像机的视场内么?
- 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。
- Lastly, feeder performance and the number of required camera fields of view for optical component centering will have additional impact on the process. 最后，喂料器的性能以及用于元器件光学对中的摄像机视场的数目对贴装工艺将有一定影响。
- 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；
- The director sweated out a camera angle with the cinematographer. 导演和电影摄影师好不容易才对好了拍摄角度。
- Outside the field of view of a television or movie camera. 避开处于电视机或电影摄像机视场之外
- 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;
- The traveller carries about a camera. 旅行者随身带着一只照相机。
- A good video camera will cost you a pretty penny. 一台好的摄像机要花掉你很多钱。
- The field artillery pounded away at the for tress. 野战炮兵连续炮击那座要塞。
- I buy some special fast film for my new camera. 我为新相机买了些特快胶卷。
- He bought two rolls of film for the camera. 他给照相机买了两卷胶卷。
- Mr Grey bought his camera on approval. 格雷先生买这架照相机，包退包换。
- The camera panned slowly across to the door. 镜头慢慢摇向门口。
- The camera zoomed in on the child's face. 摄像机镜头移向那小孩的面部。
- We forgot to take our camera when traveling. 我们旅行时忘记带照相机了。
