It substitutes numerical reconstruction for optical method to reconstruct object wave fields by computer 它是通過(guò)計(jì)算機(jī)用數(shù)字重現(xiàn)的方法代替光學(xué)再現(xiàn)重現(xiàn)物光波。
It records object wave field by interference theory , but it is different in recording media from holography 記錄過(guò)程也是利用干涉原理記錄物光波,所不同的是記錄介質(zhì)。
The reference beam comes from the object wave itself and image of the object is formed by a lens on the plane of the holographic plate , therefore the hologram is named self reference image hologram 用透鏡將物體的像成在記錄干板平面附近,參考光來(lái)自物光本身,因此稱(chēng)之為自參考像全息圖。
The major drawback of the method is the low spatial resolution of ccd arrays , because of which , the angle between the reference and the object waves must be limited to a few degrees 目前, ccd低的分辨率是數(shù)字重現(xiàn)技術(shù)的最大的制約因素。 ccd低的分辨率限制了物光和參考光之間地夾角,使得實(shí)驗(yàn)精度要求很高。
This method has some characters : during recording of the transmissive holograms the holographic grating placed in front of the holographic plate closefittingly is used as a spectroscope . the transmissive wave is served as the object wave and the diffraction wave through the holographic grating or the deflective reflect wave produced by the silicon slice is served as the reference wave , therefore the hologram is named as self - reference image hologram . the recording results are the off - axis holograms and the twin images can be separated successfully 在記錄透射型全息圖時(shí),將全息光柵緊貼置于記錄干板之前,而光柵起到了分光的作用,直透波作為全息圖的物光波,參考光是物光通過(guò)光柵后產(chǎn)生的衍射波;記錄反射型全息圖時(shí)將硅片置于記錄干板之后,利用反射硅片產(chǎn)生離軸參考光,因此系統(tǒng)僅需一束照明光束,參考光來(lái)自物光本身,因此稱(chēng)之為自參考像全息圖。
The holographic wavefront recording process records the interference pattern of the object and the reference waves , and thus forms the hologram , which simultaneously records the information about the amplitude and phase of the object waves ; the holographic wavefront reconstruction , by means of the diffracted waves , can reconstruct the original object wave from the hologram illuminated by lights 全息波陣面記錄將物光和參考光以干涉條紋記錄成全息圖,此全息圖同時(shí)記錄了物光波的振幅和相位;全息波陣面重現(xiàn),就是用光波照射全息圖,通過(guò)光的衍射,從全息圖中再現(xiàn)出原始物體的光波。
By combining the advanced computer technology and optical holography technology together , computer - generated hologram can generate holograms , which , with no demand for objects , can be reconstructed through optical ways after the computer has processed the mathematical description of object waves 計(jì)算全息是將先進(jìn)的計(jì)算機(jī)技術(shù)和光全息術(shù)結(jié)合起來(lái),利用計(jì)算機(jī)產(chǎn)生全息圖。它不需要物體實(shí)際存在,而是把物波的數(shù)學(xué)描述輸入計(jì)算機(jī)處理后,繪制出全息圖,然后用光學(xué)方法重現(xiàn)。
