西门子之星测试图卡简介

　　分辨率测试卡西门子之星测试图卡YE0161设计用于调整相机镜头和检查焦距。它由一个位于中心的大型西门子星和位于测试图角的四个较小的星组成。

　　借助低传输滤波器和低电平照明，确保相机不会在光圈处于打开位置时过调制。

　　a)光学对焦：以最大焦距调整变焦镜头的对焦。

　　b)后焦距(透镜)：通过用调节螺丝机械调节透镜，并通过a)优化，以最短焦距调整焦距。

　　c)后焦距(摄像管)：如果焦距在最大和最短焦距之间从通道到通道变化，分辨率测试卡则必须在光轴上机械地调整各个摄像管。

　　1.选择白色通道。将光学焦点设置在最大焦距。使用最短的焦距和发散聚焦调整W-通道中的摄像管，直到实现最佳聚焦。如果需要通过与光学聚焦调节交替来优化。

　　2.不改变光学焦点调节和最短焦距调整红色和蓝色摄像管，直到实现最佳聚焦。通过后焦距调整，在所有焦距(放大)和与物体的恒定距离处保持图像对焦(对焦调整)。

　　Resolution test card Introduction to the Siemens Star Test Card

　　The Siemens Star Test Card YE0161 is designed to adjust the camera lens and check the focal length. It consists of a large central star in the center and four smaller stars at the test corner.

　　With low transmission filters and low level lighting, make sure that the camera does not over-tune when the aperture is in the open position.

　　A) Optical focus: Adjust the focus of the zoom lens with the maximum focus.

　　B) Back focus (lens): Adjust the focus by adjusting the lens mechanically with the adjustment screw and by a) optimization with the shortest focal length.

　　C) Back focus (camera tube): If the focal length changes from channel to channel between the maximum and shortest focal lengths, the individual camera tubes must be mechanically adjusted on the optical axis.

　　1. Select the white channel. Set the optical focus at the maximum focal length. Adjust the camera tube in the Resolution test card W-channel with the shortest focus and divergence focus until the best focus is achieved. If needed to be optimized by alternating with the optical focus adjustment.

　　2. Do not change the optical focus adjustment and the shortest focus to adjust the red and blue camera tubes until the best focus is achieved. Adjust the focus at all focal lengths (magnification) and at a constant distance from the object by back focus adjustment (focus adjustment).Resolution test card
