      鏡頭焦距測試圖使用方法

      藉助低透射濾光片和低水平的照明確保相機調製光圈開啟位置沒有過度調節•☁·。

      a)光學聚焦✘◕·↟:調整焦距到最大變焦距離•☁·。

      b)後焦距✘◕·↟:透過調節相機鏡頭的機械螺絲到聚焦在最短焦距│✘,並交替進行最佳化光學聚焦•☁·。

      c)後焦距✘◕·↟:如果焦點從一個通道到另一個通道的最大和最短焦距個別的回升管必須在光軸機械調整•☁·。

      1.選擇白色通道•☁·。設定光學聚焦在最大焦距•☁·。在最短焦距和發散焦點調整W-通道回升管直到最佳聚焦的實現•☁·。如果有必要最佳化透過交替調整光學聚焦•☁·。

      2.調整不變光學聚焦和最短焦距的紅色和藍色回升管│✘,直到實現最佳測量聚焦•☁·。影象對焦(對焦調整)調整後焦距得到全焦段(放大)和恆定距離物件•☁·。

      影象格式由4空心箭頭連結•☁·。10個各自寬度為畫面高度0.5%的黑線和白線分別位於圖畫格式內外•☁·。可以透過線的輔助讀取影象被調整箭頭提示↟│·✘◕、枕形和桶形失真•☁·。

      從75線開始線條圖形在左側部分由25行到450行進展•☁·。在右側欄的影象以MHz為單位進行縮放│✘,從1MHz開始到8MHz結束•☁·。條圖形以5√2因子步進•☁·。

      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.

      Lens focal length test chart function

      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.
