失真发光二极管显示器和电视监视器的扫描失真效应是不相同的,在前一情况下,扫描图形的边缘发生失真,任何速度上或连接上的误差都表现为亮度变化,但目标图像并不失真。然而,在电视显示屏上,图像失真和扫描图形失真的情况相反。图1(a～e)表明转鼓扫描镜产生的主要失真实例。这些失真决定于探测器阵列在扫描视场中心转镜中的图像与转鼓转轴线的相对位置。任何探测元件的扫描速率都和探测器及其在转镜中图像间的距离成比例的,这是在和转轴垂直的方向上测量的。为
Distortion LED display and TV monitor scan distortion effect is not the same, in the former case, the edge of the scanned image distortion occurs, any speed or connection errors are shown as brightness changes, but the target image is not distorted . However, on TV displays, image distortion is the opposite of scanning graphics distortion. Figure 1 (a ~ e) shows the main examples of distortion generated by the drum scanning mirror. These distortions depend on the relative position of the image of the detector array in the center of rotation of the scanning field of view to the axis of rotation of the drum. The scanning rate of any detector element is proportional to the distance between the detector and its image in the mirror, measured perpendicular to the axis of rotation. for
