本文提出一种轴向梯度折射率光学元件的|P、|W设计方法。把对光学系统的像差要求,通过元件的|P~∞、|W~∞初级像差系数表达式,变成对于系统的结构和折射率梯度的要求。这种设计方法不仅对于单片轴向梯度折射率透镜,而且对于同时包括均匀介质元件的光学系统也是很方便的。

An |P,|W method for designing optical elements with axial-gradient indices is presented. The aberration requirement for a system is replaced by requirements on structure and index gradient by means of | P and |W expressions of primary aberration coefficients. The use of the method is not limited to simple lenses with gradient indices. It can also be used conveniently in the design of systems having homogeneous-medium elements.
