The following modes will be canceled when the main switch selector is set to l ( lock ) ae lock setting ( in the preview ae lock user setting mode ) . self - timer mode 当主选择开关设置在（锁定） ,以下的模式将被取消。自动曝光锁定设置（在预景深自动曝光锁定设置模式） ,自拍模式。
Telocentric lenses work with a wide depth of field . with a telocentric lens , you can image objects of different distances from the lens and the objects stay in focus 具端着丝粒的镜头(注:我猜是类似于针孔镜头吧)具有宽阔之景深，以具端着丝粒的镜头，你能够将由镜头不同距离之目标物成像和保持目标物在焦。
Optical rejection system is designed ; the depth of field of the projection system is calculated . the control module of measuring system is designed . an experimental system is developed 设计了光学投影系统，分析了投影系统的测量景深与测量范围的关系，设计了测量系统控制模块，构建了实验室条件下的测量系统。
3rd hole : no doubt you will be deeply attracted by the charming scenery while walking sunward or downsun on the fairway , and the difficulty of grasping the hole easily gets slipped from your mind as a result 第3洞：无论你踏着夕阳，还是迎着朝阳走在球道上，都会被这着景深深地吸引，而忘记了脚下所在的球洞难以掌握。
Conventional analog video cannot match the resolution and quality of 35 - millimeter film , but the newest digital video cameras provide approximately the same resolution as a 35mm camera and a greater depth of field 传统类比影像的解析度，无法与35 ?米电影的品质相比，不过最新的数位摄影机，已经能提供与35 ?米摄影机几乎一样的解析度，而且具有更大的景深。
Dim - ensioning system measures length , width , height and volume of parcels , even ir regular shaped parcels , as they travel on a conveyor belt at speeds up to 3 meters per second 600 feet per minute Metrologic公司的penta系列产品具有holotrak激光条形码扫描仪的扫描和分拣功能，适用于当今最快最宽的传送带系统。由于其景深最长，因而可以扫描各种体积大小的包裹。
The advantages of its image space are multi - angle , full - vision and can be observed by many persons at the same time . the physical depth cues are clear and the image is more reasonable and applicable . it can be widely used in the fields of medicine and military affairs and so on 它的成像体素直接在三维数据场中生成,图像空间具有多视角、全视景、多人同时观察的优点,物理景深清晰,能更好地展现实际情景,可广泛应用于医学、军事等领域。
True 3d volumetric display technique is a completely new research trend in computer stereo vision technique . by displaying the 3d image in 3d monitor directly , the characteristics of the image space are multi - angle , all - round view and can be observed by many persons at the same time and interact with persons directly 真三维立体显示技术( true3dvolumetricdisplaytechnique )是计算机立体视觉系统中最新的研究方向,基于这种显示技术可以直接观察到具有物理景深的三维图像,并具有全视景、多角度、多人同时观察,即时交互等众多优点。
There are plenty of techniques to get these parameters . of all the techniques , optical in - line holography has some particular advantages : non - destructive , wide size - range of the measured particles , large depth of field , direct reconstruction of 3 - d particle field , high resolution and simple set - up 在众多的测试方法中，激光同轴全息摄影法以其不干扰流场，测量粒子尺寸范围大、拍摄景深大、可再现三维粒子场信息、分辨率高以及光路布置简单等优点得到了广泛的应用。
