在白色背景上布置有14条水平线和19条垂直线的网格结构。网格应由对应的网格电子生成测试器生成。网格结构也对应于T01几何测试图的球结构。
应用
测试图设计用于电视摄像机的操作调整和控制。网格允许对扫描线性进行粗略的视觉评估,并且实现线用于调整配准的目的。
图卡也可用黑色背景上的白线。
A grid structure of 14 horizontal and 19 vertical lines is arranged on a white background. The grid corresponds to a grid generated electronically by a test generator. The grid structure also corresponds to the ball structure of the T01 Geometry Test Chart.
UTILIZATION
The test chart is designed for operational adjustment and control of TV cameras. The grid permits rough visual appraisal of scan linearity and the lines serve the purpose of adjusting registration.
The chart is available also with white lines on a black background.
