摘要
本文根据矩阵光学理论和ABCD定律,导出了高斯光束经锥形发散梯度折射率纤维透镜变换的束腰共轭成像公式在。|l_o—l_f|>>Z_0的球面波近似条件下,本文结果化为几何光学成像公式。
Based on matrix optics theory and ABCD law the beam waist conjugateimaging formulas for Gaussian beam transformation through a conical defocusinggradient index(GRIN) fiber lens are derived. Under the spherical wave appro-ximation, i.e Z_o<<|l_o-l_f|, the results obtained here can be reduced to the geometricaloptics formulas
