defocus-focus 解釋
聚焦
  • defocus : 去聚焦
  • focus : n （pl focuses foci ）1 【物理學】焦點。2 【物理學】焦距；聚焦，對焦點，配光，對光。3 （活動興趣...
  1. We simulate the practicality system to experimentalize, obtain the relation between defocus and focus error signal, make it a condition that na = 0. 625 and n = 1. 7979

    並模擬實際系統，實驗得出當臨界角棱鏡的折射率n = 1 . 7979 、物鏡的數值孔徑na = 0 . 625時，離焦量與離焦誤差信號的關系曲線。
  2. The aim of defocus detection is to achieve high etching quality by providing the defocus error signal for focus - servo system which can make the etching spot focus accurately

    離焦檢測的任務是為聚焦伺服系統提供聚焦誤差信號，使寫入光斑能夠精確聚焦，從而保證刻蝕質量。
  3. We acquired best restoration of defocus images using one blurred image, and estimated the focused position according to radius of blurred circles at two different lens positions, the focus error was less than 5 %

    利用單幅圖像，用圖像恢復的手段得到了準焦位置圖像的最佳恢復；利用在兩個位置所得圖像，用模糊圓半徑估計出準確對焦位置，對焦誤差小於5 。
  4. The thesis is divide ^ into several chapters. ( 1 ) : firstly, the paper briefs the principles and research status quo of auto - focus in digital imaging systems, introduces a dfd ( depth form defocus ) auto - focus method based on frequency analysis

    本文包含了以下一些內容： （ 1 ） ：首先對成像原理進行了簡要的介紹和說明，接著分析了自動對焦技術的原理和作用背景，引入一種基於頻域分析的離焦深度自動對焦方法。
