The signal beam can be recreated by illuminating the medium with a beam identical to the original reference beam 通过用和原始参考光相同的光束来照亮感光介质可以还原信号光。
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,信号光会和另一独立的参考光相遇,当两个光束相交时,它们会在感光介质中制造一个干涉图样。
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 用透镜将物体的像成在记录干板平面附近,参考光来自物光本身,因此称之为自参考像全息图。
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 介绍了一种基于对接入加密数据通道进行加密的方法,即对参考光的相位进行正交相位编码; 4 .双随机相位编码加密光存储。
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 这种方法不需要光束偏转器件,只需要机械运动平台,仅通过平台的移动,就可以实现参考光束入射角度的变化,而且寻址的精确性并未降低。
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 我们还进行了在光刻胶上的旋转复用存储实验,在15度的角度下,复用的图像的交叉干扰大大降低。实际的存储密度达到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 在光路调整中,它对测量光与参考光的合光光束是否垂直于探测器光敏面要求不高,但对两光束合光同轴度则有严格要求。
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 摘要为了分析光致聚合材料记录的谱面全息图在再现过程中发生“擦除”现象,将谱面全息图看作由不同角谱的物光与参考光在光致聚合材料内形成的不同倾斜角度的光栅总和。
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 摘要本文根据芳纶纤维加固钢筋混凝土梁和未加固的混凝土参考梁的抗弯性能静载试验研究,分析了芳纶纤维加固钢筋混凝土受弯构件的破坏过程,研究了加固后钢筋混凝土受弯构件正截面的破坏特征、受力特点及影响因素(粘贴层数和配筋率) 。
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 因而干涉仪系统达到高精度的基础是:频率及频差稳定的双频激光源、稳定的等效腔长;测量光与参考光合光后有很高同轴度的光路结构;能可靠记录相位差变化周期数的细分及可逆计数系统三部分。
