  1. The holographic lens, which is designed according to bragg condition to eliminate aberrations, has both high efficiency and low aberration, and can be used in a certain narrow - band condition. a example and its results are also given in this paper

    該方法採用雙片全息透鏡復合,按使用條件在布喇格條件下進行消三級設計,製作設計的全息透鏡具有高衍射效率高、小的特點,可以滿足任意給定的窄帶光場合。
  2. But for some special medium materials, such as liquid crystal display controller pcb, magnifiers must be used to gather images to gain enough precision of inspection for the weak contrast between the basic board and the conductor. the images near the light axes are much cleared than that far away from the light axes, so the images can not be simply segmented by black and white and inspected with the methods of pcb which are based on the black white image

    但對於一些特殊介質材料,如液晶顯示控制電路板的檢測,由於基板和導體之間對比度不大,而且為了達到檢測精度,必須採用放大鏡頭進行圖採集,成系統光附近的圖質量較好,而偏較遠的圖質量較。不能通過簡單二值化來很好地分割圖,而已有的印刷電路板檢測方法都是建立在二值圖進行分析的基礎上。
  3. Compared with the ordinary optimization algorithm of calibration, this algorithm is simple, less computational and high accuracy. finally, the paper put forward the ranging method based on similar triangle principle. it gives two ranging models according cooperation object vertical in the optical axis or not vertical in the optical axis and does experiment

    最後,本文提出了一種基於相似三角形原理的測距方法,根據合作目標與攝機主光垂直與不垂直兩種情況,給出了兩種測距模型,建立實驗系統並進行了實驗,通過近距段與遠距段的測距結果與誤分析驗證了此方法的有效性,能夠準確的確定合作目標的位置,計算簡單,測量精度高,具有重要的理論意義和工程使用價值。
