The signal beam can be recreated by illuminating the medium with a beam identical to the original reference beam 通過用和原始參考光相同的光束來照亮感光介質(zhì)可以還原信號光。
This “ signal beam ” then meets a separate reference beam , and where the two beams intersect they create an interference pattern in a light - sensitive medium 然后,信號光會和另一獨(dú)立的參考光相遇,當(dāng)兩個(gè)光束相交時(shí),它們會在感光介質(zhì)中制造一個(gè)干涉圖樣。
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,參考光來自物光本身,因此稱之為自參考像全息圖。
This chapter introduces one technique which based on encrypting the access of storage data , this can be done by coding the phase of reference beams by use of orthogonal - phase - code 介紹了一種基于對接入加密數(shù)據(jù)通道進(jìn)行加密的方法,即對參考光的相位進(jìn)行正交相位編碼; 4 .雙隨機(jī)相位編碼加密光存儲。
This method doesn ’ t need beam deflection device and can change the reference beam incidence angle with mechanical movement platform only . and the accuracy of system is not getting lower 這種方法不需要光束偏轉(zhuǎn)器件,只需要機(jī)械運(yùn)動平臺,僅通過平臺的移動,就可以實(shí)現(xiàn)參考光束入射角度的變化,而且尋址的精確性并未降低。
We also store several images on the same spot with reference beams of different directions ( peristeophic multiplexing ) , when each hologram is separated by 15 , the crosstalk noise decreases greatly , the storage density can be obtained 10 bits / cm finally 我們還進(jìn)行了在光刻膠上的旋轉(zhuǎn)復(fù)用存儲實(shí)驗(yàn),在15度的角度下,復(fù)用的圖像的交叉干擾大大降低。實(shí)際的存儲密度達(dá)到10 ~ 7bits cm ~ 2 。
During adjusting beam paths , the co - beam , a combination of the measuring beam and the reference beam , is not restricted to being perpendicu lar to the light sensitive surface of the object , but keeping the measuring beam and the reference beam co - axial proved to be crucial 在光路調(diào)整中,它對測量光與參考光的合光光束是否垂直于探測器光敏面要求不高,但對兩光束合光同軸度則有嚴(yán)格要求。
In order to investigate the phenomenon that holograms tend to be deteriorated on baing recorded in photopolymers with shrinkage , a fourier hologram is taken with slant gratings formed by the reference beam and object beams of different space - frequency 摘要為了分析光致聚合材料記錄的譜面全息圖在再現(xiàn)過程中發(fā)生“擦除”現(xiàn)象,將譜面全息圖看作由不同角譜的物光與參考光在光致聚合材料內(nèi)形成的不同傾斜角度的光柵總和。

Therefore , the three fundamentals required to obtain high precise measurements are : 1 ) frequency stability and frequency difference stability of the double - frequency laser source as well as the stable equivalent length of bore ; 2 ) the measuring beam and the reference beam are placed very co - axially ; 3 ) capability of recording the sub - division of the period of phase change and a reversible counter system 因而干涉儀系統(tǒng)達(dá)到高精度的基礎(chǔ)是:頻率及頻差穩(wěn)定的雙頻激光源、穩(wěn)定的等效腔長;測量光與參考光合光后有很高同軸度的光路結(jié)構(gòu);能可靠記錄相位差變化周期數(shù)的細(xì)分及可逆計(jì)數(shù)系統(tǒng)三部分。
