      镜头焦距测试图简介

      分辨率测试卡镜头焦距测试图TE100用于调整相机镜头,检查后焦距和分辨率,并确认枕形和桶形失真。它包括一个西门子之星,以及几个黑白线对勾勒出箭头形状组成。

      镜头焦距测试图功能

      1、照相机镜头的调整

      2、检查后焦距

      3、检查分辨率

      4、确认枕形和桶形失真

      镜头焦距测试图使用方法

      借助低透射滤光片和低水平的照明确保相机调制光圈打开位置没有过度调节。

      a)光学聚焦:调整焦距到最大变焦距离。

      b)后焦距:通过调节相机镜头的机械螺丝到聚焦在最短焦距,并交替进行优化光学聚焦。

      c)后焦距:如果焦点从一个信道到另一个信道的最大和最短焦距个别的回升管必须在光轴机械调整。

      1.选择白色通道。设置光学聚焦在最大焦距。在最短焦距和发散焦点调整W-通道回升管直到最佳聚焦的实现。如果有必要优化通过交替调整光学聚焦。

      2.调整不变光学聚焦和最短焦距的红色和蓝色回升管,直到实现最佳测量聚焦。图像对焦(对焦调整)调整后焦距得到全焦段(放大)和恒定距离对象。

      图像格式由4空心箭头链接。10个各自宽度为画面高度0.5%的黑线和白线分别位于图画格式内外。可以通过线的辅助读取图像被调整箭头提示、枕形和桶形失真。

      从75线开始线条图形在左侧部分由25行到450行进展。在右侧栏的图像以MHz为单位进行缩放,从1MHz开始到8MHz结束。条图形以5√2因子步进。

      Introduction to lens focal length test chart

      Lens focal length test chart TE100 is used to adjust the camera lens, check the back focus and resolution, and confirm the pillow and barrel distortion. It consists of a star of Siemens, as well as several black and white lines that outline the shape of the arrows.

      1, the camera lens adjustment

      2, check the back focal length

      3, check the resolution

      4, to confirm the pillow and barrel distortion

      Lens focal length test chart using the method

      With the low transmittance filter and low level of illumination to ensure that the camera modulation aperture open position is not over-adjusted.

      a) Optical focus: adjust the focal length to the maximum zoom distance.

      b) Back focus: Adjust the camera lens by adjusting the camera's lens to focus on the shortest focal length and alternately optimize the optical focus.

      c) Back focus: If the focus is from one channel to another, the maximum and shortest focal lengths of the individual recoil 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 W-channel riser at the shortest focal length and divergence focus until the best focus is achieved. If it is necessary to optimize the optical focus by alternately adjusting.

      2. Adjust the invariant optical focus and the shortest focal length of the red and blue recoil tubes until the best measurement focus is achieved. Image Focus (Focus Adjustment) Adjusts the focal length to get full focus (magnified) and constant distance objects.

      The image format is linked by 4 hollow arrows. 10 black and white lines each with a width of 0.5% of the screen are located inside and outside the picture format. Can be read by the auxiliary image of the line by adjusting the arrow prompt, pincushion and barrel distortion.

      Line lines start from line 75 on the left side from 25 to 450 rows. The image on the right side of the column is scaled in MHz, starting at 1MHz and ending at 8MHz. The bar graph is stepped by the 5√2 factor.
