From the principle of holography , resolving power and design method of digital image are being discussed 從數(shù)字圖像的全息記錄原理出發(fā),討論了數(shù)字圖像的分辨率及設(shè)計(jì)方法問(wèn)題。
Holography was one of the most important physical inventions in the last century . the british scientist dennis gabor brought the principle of holography firstly in 1948 全息術(shù)( holography )是上世紀(jì)最重要的物理發(fā)明之一,它的原理由英國(guó)科學(xué)家gabor于1948年最早提出。
In 1947 , professor dennis gabor , a researcher at london ' s college of science and technology , discovered the principle of holography while seeking ways to increase the resolution of fine detail in pictures of objects seen with electron microscopes 1947年,倫敦科學(xué)技術(shù)學(xué)院的研究員丹尼斯?加布爾伯教授發(fā)現(xiàn)了全息技術(shù)的原理,當(dāng)時(shí)他在利用電子顯微鏡尋求提高物體成像細(xì)節(jié)清晰度的方法。
One of the ways for a microcosm to bring about change within the greater whole , the macrocosm , is to change the microcosm . this follows the principle of holography : the whole is contained within the part . we can change the earth if we can manage to rebalance our communities 要改變整體大宇宙的作法之一就是改變我們自身的小宇宙,因?yàn)橐勒招∮钪婕创笥钪娴脑瓌t:整體包含在部分之內(nèi),如果我們可以平衡自己的生活環(huán)境及所屬的團(tuán)體,我們就可以改變地球。
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(chǎn)生優(yōu)質(zhì)的聚焦能力與效率,本研究采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(diào)制藥劑比例成分,并依嚴(yán)格的制作步制成重鉻酸明膠全像片外,并采用不同角度重覆曝光方式改良干涉式波帶板無(wú)法自動(dòng)追蹤的缺點(diǎn),經(jīng)過(guò)多次試驗(yàn)與改進(jìn),藉以形成具備高繞射效率和自動(dòng)追蹤功能的全像光學(xué)波帶板。
