布拉格衍射 meaning in Chinese
bragg diffraction
Examples
- Acoustical imaging by bragg diffraction
布拉格衍射声成像 - At the different recording angles , the raman - nath diffraction and bragg diffraction phenomenon are observed , respectively . then , the wavelength selectivity and the relationship of diffraction efficiency and polarization state are discussed when the recording angle of 60 ? formed by two writing beam
分别观察到了写入光束夹角不同时光栅的拉曼-奈斯衍射和布拉格衍射现象，并对双光束夹角为60时写入光栅的波长选择性及衍射效率与入射光偏振态的关系进行讨论。 - And the parameter data and the figures have not been calculated ever . compared with the performance curves of the primary aod , the aod with the optimum design shows great capacity : at the extreme point of bragg diffration the optimized one obtain a 2 . 4 times wilder relative 3db bragg bandwidth than the primary one ; and with the same relative 3db bragg bandwidth which is 0 . 67 , the optimized aod has a relative 2 times of the the primary aod
用图示的方法将优化设计后的曲线与非跟踪的曲线进行对比,在进入布拉格衍射区的临界点处经优化设计的器件相对带宽达到非跟踪器件的相对带宽的2 . 4倍;在相对带宽? f = 0 . 67的情况下,经优化设计的器件相对长度是非跟踪器件相对长度的2倍。 - For multi - dimension acousto - electro - optical effect , the momentum mismatch is solely replaced by mismatch caused by electric field . based on this , one - dimension acousto - electro - optical coupled wave equation and multi - dimension acousto - electro - optical coupled wave equation are founded and their diffractive efficiency formulas are also deduced respectively
通过对声光互作用耦合波方程中的动量失配进行修正,分别得到了一维反常声电光布拉格衍射的耦合波方程以及多维声电光效应耦合波方程的表达式,并进一步得到了相应的衍射效率的计算公式。
