中文摘要：

磁电机眼(瞬间)与微波 magnetostatic 波浪( MSW )指导光波浪联合同时由信号能导致的多重收音机频率( RF )激动 RF 信号的 multifrequency 衍射效果然后并行处理能被衍射效率( Des )是的特征使用认识到近似在里面到 RF 信号紧张和衍射角度的直接比例与在线性瞬间相互作用区域以内的相应 RF 信号的频率有关。在这份报纸，学习了是在一阶的瞬间相互作用近似的 multifrequency 瞬间布拉格衍射，并且获得是为原则衍射效率(PDE ) 的近似分析表示。另外，提出基于单个频率的衍射是 RF 信号的相对紧张的一个平行成像方法。由计算和分析，相对错误是为在内的三个 RF 信号的盒子的不超过 0.3 dB 60 MHz 的频率空间，这被显示出。

英文摘要：

Magneto-optic （MO） coupling of guided optical waves with microwave magnetostatic waves （MSWs） simultaneously excited by multiple radio frequency（RF） signals can lead to multifrequency diffraction effects and then parallel processing of RF signals can be realized by using of the characteristics that diffraction efficiencies（DEs） are approximately in direct proportion to RF signals intensities and diffraction angles are related to frequencies of the corresponding RF signals within linear MO interaction region. In this paper, studied is the multifrequency MO Bragg diffraction in first-order MO interaction approximation, and obtained was the approximate analytical expression for principle diffraction efficiency（PDE）. Also, put forward was a parallel imaging method of relative intensity of RF signals based on single-frequency diffraction. By calculation and analysis, it is shown that the relative error is not more than 0.3 dB for the case of three RF signals within the frequency space of 60 MHz.
