摘　　要：用波动光学理论，籍助变分法，导出一种抛物型发散梯度折射率纤维透镜中高斯光束的成像公式，并与几何光学结果作了比较。结果表明，光束束宽对成像特性有显著影响。In this paper the imaging formulas of Gaussian optical beam through a divergent parabolic GRIN fiber lens are derived from the wave optics theory and the variational method and compared with the geometrical optics results.It is shown that the effect of the beam widthon the imaging characteristics is signficant.
