三恩时棋盘分辨率测试卡几何形状畸变一致性

测试卡说明

YE06A测试卡被设计用来检查几何和分辨率。
数据
测试卡类似于一个由13×18的黑色和白色正方形区域以及由矩形区域在对应于电子测试生成器14/19网格光栅线边缘所包围的棋盘。（整个图卡发生器的水平网格线被划分为相应于42行）。
九个扇形星内圆线条标出625线结构。较大的圆形线条标出312线的结构。横向对应的垂直线光栅分布着33个白格。它们对应于2，3.5和5MHz频率栅格。
应用
•检查几何形状和光栅的一致性，如果有必要用电子生成网格的装置。
•检查信号生成的均匀性。
•检查分辨率及其在图像区域分布。
•检查后焦距。

The YE06A test chart is designed for checking geometry and resolution.
DATA
Similar to a chessboard the test chart is composed of 13 x 18 black and white square fields which are surrounded by rectangular at the edges that correspond to the 14/19 grid raster lines of electronic test generators. (The division of the horizontal grid lines of these generators corresponds to 42 lines per complete picture.)
The inner circular lines of the nine sector stars mark a 625-line structure. The larger circular lines mark a structure of 312 lines. Horizontal resp. vertical line rasters are arranged in 33 white fields. They correspond to frequency raster of 2, 3.5 and 5 MHz.
UTILIZATION
•Checking geometry and the congruency of raster, by means of an electronically generated grid, if necessary
•Checking the uniformity of the signal generation.
•Checking resolution and its distribution over the picture area.
•Checking back focal distance.
