动态分辨率测试卡TE114简介

　　分辨率测试卡动态分辨率测试卡TE114是专门为检测TV摄像机分辨率特性以及TV传输系统“串色”干扰而研发的。测试卡由一个波带片分布满整个图像区域，其中图像上的环以线性增加的空间频率向外扩展。图像上水平方向边缘的空间频率可以达到8MHz，垂直方向边缘的空间频率达到6MHz。测试卡的角落的空间频率为10MHz。

　　动态分辨率测试卡TE114用于确定的TV摄像机和TV传输系统的以下特征

　　水平，垂直和对角方向的分辨率

　　分辨率取决于扫描的位置

　　水平和垂直光圈校正效果

　　照相机的扫描光束的象散(阀摄像机)

　　带片和电视光栅对应彩色显像管荫罩结构之间干涉的影响。

　　PAL编码的效果(例如“串色”)在水平和垂直方向上照相机(或测试卡)运动过程中反应：动态分辨率，时间干涉干扰分辨率测试卡

　　分辨率测试卡该动态分辨率测试卡特别适合与电视信号滤波器的多维测量装置(水平、垂直以及如果可能在时间上)一同使用。这些装置可以是TV摄像机镜头光圈矫正器，也可以是标准PAL解码器(带线延迟)和梳妆滤波PAL解码器。带片也可以被使用在MAC系统(根据色彩线序传输)的预处理和预过滤效果的测定。带片测试图已经被证实可以可靠的测量CCD摄像机。

　　Introduction to Dynamic Resolution Test Card TE114

　　Dynamic resolution test card TE114 is specifically designed to detect TV Resolution test card camera resolution characteristics and TV transmission system "string color" interference and research and development. The test card is distributed over a whole region by a band, where the ring on the image extends outwardly with a linearly increasing spatial frequency. The spatial frequency of the horizontal edge of the image can reach 8MHz, and the spatial frequencyResolution test card of the vertical edge is 6MHz. The corner frequency of the test card is 10MHz.

　　The dynamic resolution test card TE114 is used to determine the following characteristics of the TV camera and TV transmission system

　　Horizontal, vertical and diagonal directions

　　The resolution depends on the position of the scan

　　Horizontal and vertical aperture correction effects

　　The astigmatism of the camera's scanning beam (the valve camera)

　　The effect of band and TV gratings on the interference between the mask structure of the color picture tube.

　　PAL encoding effects (eg "string color") in the horizontal and vertical directions of the camera (or test card) during the movement of the reaction: dynamic resolution, time interference interference

　　The dynamic resolution test card is particularly suitable for use with multidimensional measuring devices (horizontal, vertical,Resolution test card and possibly in time) of a television signal filter. These devices can be TV camera lens irisizers, also can be standard PAL decoder (with line delay) and dressing filter PAL decoder. The tape can also be used in the determination of the preprocessing and pre-filtering effects of the MAC system (according to color line order). The tape test chart has been proven to reliably measure the CCD camera.
