一类抛物型发散梯度折射率棒透镜的物像变换

The obiect-image transformation of a kind of parabolic divergent GRIN rod lenses

本文研究一类抛物型发散梯度折射率棒透镜中高斯光束的传播。结果表明，在一般情况下，几何光学模型不能描述高斯光束经这种透镜的物像变换。

Gaussian beam propagation through a kind of parabolic divergent GRIN rod lenses is studied.It is shown that the geometrical optics model can not be used to describe the object-image transformation of Gaussian beam through the lens under the general case.
