摘　　要：通过傍轴近似及相位匹配技术,推导得到了旋转抛物透镜的反射矩阵及其相应的折射矩阵.利用推导出的反射、折射矩阵,得到了入射光束经旋转抛物透镜作矩阵变换后,其光斑及光波波前曲率半径的变换关系式.为设计具有旋转抛物透镜的特殊光学系统提供了便利.Based on the paraxial approximation and matching the optical phase, the ABCD matrices for reflection and refraction of Gaussian light beams at surface of the parabolic lens of revolution that separate media of different refractive indices are deduced. By utilizing the ABCD matrices, the corresponding transforming equations for the spot sizes and wave-front radii of the incident beams are obtained. These brings convenience to design the special optical systems with this kind of elements.
