本文叙述球形梯度折射率透镜的象差。介绍从球形坐标到直角坐标的变换。有了这些变换,就能在直角坐标中进行折射率多项式的计算以及对随后的象差系数和光线追迹数据进行分析。本文展示靠简单变换梯度曲率改变梯度象差符号的能力。
This article describes the aberration of a spherical gradient index lens. Describes the transformation from spherical coordinates to Cartesian coordinates. With these transforms, the refractive index polynomial can be calculated in Cartesian coordinates and the subsequent aberration coefficients and ray tracing data can be analyzed. This article shows the ability to change gradient aberration symbols by simply transforming gradient curvature.
