It is confirmed that the measuring accuracy is concerned with the radius of curvature and the distance between two measuring points.
仪器的测量精度同被测镜的曲率半径及两测量点的间距有关。
It can freeze, store, display, magnify and rotate the video signals. It can measure the distance between two points, the angles, the radius of curvature and the point density.
能对获得的视频信号进行冻结、存储、再现、放大、空间旋转、负片等处理，能测量两点间距离、夹角、曲率半径、点密度。
