In this paper, we consider the aberrations and design of graded-index (GRIN) rods for use as image relays. Aberration formulas are derived based on the ray path solutions previously published by the authors. The aberrations are then minimized by selecting an optimal radial refractive index variation. We assume no index variation along the axis and also consider only monochromatic aberrations. Design curves and data on the number of resolvable spots are included. The accuracy of the aberration formulas is compared with total aberrations computed numerically.
在本文中，我们考虑用作图像中继的渐变折射率（GRIN）棒的像差和设计。基于作者先前发表的光线路径解推导出像差公式。然后通过选择最佳的径向折射率变化来使像差最小化。我们假设沿轴没有折射率变化，并且仅考虑单色像差。文中还给出了设计曲线和可分辨光斑数量的数据。将像差公式的精度与数值计算得到的总像差进行了比较。
