数值孔径为０．０７的多模光纤束与受激布里渊散射位相共轭镜组成的双光程装置中，输出光束的远场分布里典型的二维列阵孔径的衍射花样，输出光能分布在０．０２６ｒａｄ内，即由单根光纤芯径的衍射极限所决定的范围内，远小于由数值孔径所决定的高阶模相应的发散角范围，并且补偿了由光纤束不均匀性带来的缺陷。
In a dual optical path device consisting of a multimode optical fiber bundle with a numerical aperture of 0.07 and a conjugate mirror with a stimulated Brillouin scattering phase, a typical two-dimensional array aperture diffraction pattern is output in the far-field distribution of the light beam, the output light Can be distributed within 0.026 rad, that is, within the range determined by the diffraction limit of a single fiber core, much less than the corresponding divergence angle range of a higher order mode determined by the numerical aperture and compensated for the difference caused by the fiber bundle inhomogeneity Defects.
