In course of auto - focusing, the paper takes the sum of the square of gray difference as focal distance evaluation function to decided that image is in focus or not quickly and put forward an effective auto - focus searching way based on threshold value and curve fitting. these improve speed and precision of auto - focusing
在自動聚焦過程中,論文採用了圖象的灰度差分的絕對值之和的平方作為焦距評價函數,解決了是否正確聚焦的快速判斷問題;採用了一種行之有效的基於閾值和曲線擬合的自動聚焦搜索方式,使聚焦速度和精度都得到了很大的提高。Since the dichromated gelatin has a higher diffraction efficiency in all holographic recording materials, the aim of this research is to use dichromated gelatin as the recording material and to make use of the principle of holography to design holographic optical components, especially in fabrication procedure of dichromated gelatin film and in experimental technique to form a high diffraction efficiency using different angular exposure method
為了產生優質的聚焦能力與效率,本研究採用目前具有最高繞射效率( 80 ~ 90 % )的重鉻酸明膠材料作為感光劑,除了自行調制藥劑比例成分,並依嚴格的製作步製成重鉻酸明膠全像片外,並採用不同角度重覆曝光方式改良干涉式波帶板無法自動追蹤的缺點,經過多次試驗與改進,藉以形成具備高繞射效率和自動追蹤功能的全像光學波帶板。Automatic focusing action
