頻閃響應
英文
stroboscopic effect-
Various solutions such as raising response speed of lcd pixels, raising frame frequency, back light blinking, back light scanning, black field insertion and image processing were reviewed
討論了提高液晶像素的響應速度、提高幀頻、背光源閃爍、背光源掃描、插入黑場和採用圖像處理技術等多種解決方法，並對各種方法進行了分析和評論。On the following, on the basis of formulas given above, three kinds of effects due to ionosphere are presented : image shift due to group delay which was caused by the difference between the group velocity and the velocity of light in the ionosphere ; image distortion due to ionospheric dispersion which can create second phase error of lfm signals ; the last, the phase perturbation caused by the irregularities of the ionosphere can reduce the coherent length and affect azimuthal resolution
文中主要研究了電離層的三種影響：信號經過電離層傳播的群延遲引起的成像偏移；電離層的色散效應給線性調頻信號帶來二次相位誤差，導致圖像退化、失真；以及電離層的閃爍、湍流等不規則性引起的信號相位起伏。在此基礎上，比較分析了不同波段、帶寬條件下電離層的影響。Scanning frequency has reached over 240hz which makes the menu stable and no flicker. in using actually, we use vidicon shoot the display screen. and then we can observe the photo is very clear from the vidicon
2掃描場頻達到了240hz以上，畫面穩定無閃爍，在實際應用中，用攝像機拍攝顯示屏，攝像機中觀測到的圖象十分清晰，沒有同步滾動條，若現場有電視轉播，顯示屏不會影響轉播畫面的質量。
