reference beam meaning in English
参比束
参考光束
基准光束
基准射束
Examples
- 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。
