  • 例句與用法
  • 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,信號光會和另一獨立的參考光相遇,當兩個光束相交時,它們會在感光介質中制造一個干涉圖樣。
  • 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據通道進行加密的方法,即對參考光的相位進行正交相位編碼; 4 .雙隨機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器件,只需要機械運動平臺,僅通過平臺的移動,就可以實現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
    我們還進行了在光刻膠上的旋轉復用存儲實驗,在15度的角度下,復用的圖像的交叉干擾大大降低。實際的存儲密度達到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過程中發生“擦除”現象,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形成的不同傾斜角度的光柵總和。
  • Based on the test of the flexural performance of reinforced concrete beams strengthened with aramid fiber reinforced plastics ( afrp ) and reference beams , this paper analyzes the failure process and characteristics of the strengthened beams and factors that affect the failure of the strengthened beams
    摘要本文根據芳綸纖維加固鋼筋混凝土梁和未加固的混凝土參考梁的抗彎性能靜載試驗研究,分析了芳綸纖維加固鋼筋混凝土受彎構件的破壞過程,研究了加固后鋼筋混凝土受彎構件正截面的破壞特征、受力特點及影響因素(粘貼層數和配筋率) 。
  • 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
    因而干涉儀系統達到高精度的基礎是:頻率及頻差穩定的雙頻激光源、穩定的等效腔長;測量光與參考光合光后有很高同軸度的光路結構;能可靠記錄相位差變化周期數的細分及可逆計數系統三部分。
