频率响应测试图卡简介
分辨率测试卡频率响应测试图卡TE152用于检查摄像机的频率响应。测试图在整个图像区域上显示范围从1到8 MHz的线光栅。
在线栅格（在黑色周围区域）下面有具有相应MHz数字的线标记。 分辨率测试卡图像左侧和右侧的条（每侧2个黑色和白色周期）的频率为0.5 MHz，用作参考值。 线光栅的宽度逐步减小，但不在黑白周期内。 在两个MHz周期的白色整数之间，条宽度以20个常规步长减小。
在示波器的帮助下，可以检查摄像机的频率响应。 为此，将实际测试图形图像外部的MHz标记带入照相机图像是有用的。
ntroduction to frequency response test cards
Frequency response test card TE152 is used to check the frequency response of the camera. The test chart displays line gratings ranging from 1 to 8 MHz across the entire image area.
The line grid (under the black surrounding area) has a line mark with the corresponding MHz number. The frequency of the left and right sides of the image (2 black and white on each side) is 0.5 MHz and used as a reference. The width of the line grating is gradually reduced, but not in the black and Resolution test card white period. Between two white cycles of two MHz cycles, the strip width is reduced by 20 normal steps.
Resolution test card With the help of the oscilloscope, you can check the camera's frequency response. For this reason, it is useful to actually bring the MHz mark outside the graphic image into the camera image.
