Sine-Image综合测试卡简介

　　Sine-Image综合测试卡 YE05是专门为电视摄像机 一般(视觉)评估而设计的。这张测试卡主要用于电子相机传输特性的评估而设计的。圆形图形用来进行扫描线性粗略评价。分布在图像2-MHz-line位置的光栅能够在水平和垂直方向上偏移线性度监督。光栅之间的距离应该尽可能的相等。

　　在线路选择开关示波器的帮助下，应用垂直楔形栅格能够建立调制深度频率响应。倾斜的1-MHz块的信号被用作参考值。楔形栅格能够进一步做出分辨极限的视觉评价。 此外，串色干扰、陷波滤波和梳状滤波效果可以被观察到。

　　在灰楔块正方形三对角线使用线性交错进行检查。该行的阶梯形接收表示双绞线。

　　密度分为4个等级标准从D=0.15增加到D=1.65(对比度32：1)该测试卡的密度在D =0.15等级。周边地区的密度为D〜0.75。

　　Introduction to SineImage Integrated Test Card

　　SineImage integrated test card YE05 is designed for TV camera general (visual) evaluation and design. This test card is mainly used for the evaluation of electronic camera transmission characteristics of the design. The circular graph is used to perform a rough linear evaluation of the scan. The gratings distributed at the image 2-MHz-line position can be offset by linearity in the horizontal and vertical directions. The distance between the gratings should be as equal as possible.

　　With the help of a line selection switch oscilloscope, a vertical wedge grid can be used to establish a modulation depth frequency response. The signal of the tilted 1-MHz block is used as a reference value. The wedge-shaped grid can further make a visual evaluation of the resolution limit. In addition, the crosstalk, notch filtering and comb filtering effects can be observed.

　　The triangular diagonal of the gray wedge is checked by linear staggering. The ladder of the line receives twisted pair.

　　The density is divided into four grades from D = 0.15 to D = 1.65 (contrast 32: 1) The density of the test card is D = 0.15. The density of the surrounding area is D ~ 0.75.
