5) Field of view
视场
1.
To improve the imaging quality of CCD camera and make the lens small in size,compact in structure,the wide field of view(WFOV) optical lens with the aspheric surface was designed.
为提高CCD照相机的成像质量,同时使镜头结构紧凑、小型化,在大视场光学镜头的设计中,采用非球面设计。
2.
The measured temperature of a target in full field of view is the real temperature.
全视场目标所测得的温度为目标的真实温度,但是现实中由于距离等因素的影响,不能保证每次测量都让目标充满整个视场,背景辐射对测量结果一定会产生影响,因此准确测量未充满视场目标(本文称为半视场目标)的方法将有重大意义。
3.
To ameliorate the field of view of Cassegrain optical system,a diffractive optical element(DOE) is first successfully introduced to the Cassegrain optical system and the design scheme is provided in this paper.
为了改善卡赛格林光学系统的视场,首次将衍射透镜成功地引入大视场卡赛格林光学系统的设计中并给出了设计方案。
6) field-of-view
视场
1.
Research of the methods for enlarging the field-of-view in digital holography;
扩大数字全息视场的方法研究
2.
The field-of-view of a scanning laser radar which adopts a pre-objective beam steering optical antenna is discussed - It shows that the scanning field-of-view is usually smaller than the defined field-of-view of the antenna telescope.
分析了出瞳扫描方式扫描视场角与激光雷达光学系统参数的关系，认为最大扫描现场角比主天线望远镇静态视场角小。
3.
To enlarge the field-of-view of digital holographic surface measurement,so that digital holography can be applied in three-dimensional(3-D) surface measurement of large objects,based on Fresnel off axis digital holography,different part of the object is illuminated singly and their holograms are recorded respectively.
为扩大数字全息的测量视场,使数字全息可以应用于大物体三维形貌的测量,利用菲涅耳离轴数字全息,让照明光依次照明物体的各个区域并分别记录全息图,利用精密电控旋转台精确控制参考光的入射角以保证每次记录时物参角不变,通过参考光入射角的变化量确定物体不同被照明区域之间的位置关系,对获得的物体去包裹的相位图进行拼接,进而得到整个物体的三维形貌。
补充资料：视场
视场代表着摄像头能够观察到的最大范围，通常以角度来表示，视场越大, 观测范圉越大。例如有些摄像头的视场是50度，而有些是58度，后者相比前者在同等距离的情况下就能拍摄到更大的景物范围。目前一般的摄像头的视解均在52度左右，更有甚者可达180度、360度（摄像头底座固定，镜头可以作一周旋转）。
