提出了采用两个折射-衍射元件对人眼系统在14°范围内进行色差校正的光学系统设计方法。基于系统光学性能的评价与单片折射-衍射元件色差校正系统的对比验证了本文提出的色差校正系统的性能。结果表明：两种色差校正系统都可以很好地校正人眼的轴向色差。但是，单片折射一衍射色差校正系统引入了横向色差，其由校正前的14．51μm增加到81．4μm，严重影响了边缘视场处的成像质量。而采用双片折射一衍射元件的色差校正系统可同时对轴向色差和横向色差进行校正，使横向色差降为1．64μm。设计的色差校正系统可有效提高视网膜的成像质量，并可用于视觉仪器。

A chromatic corrector with two refractive-diffractive hybrid elements is designed for a wide field-of- view of 14° to correct chromatic aberrations in human eyes. The performance of the corrector based on several optical criteria is compared with a chromatic eorrector with single refractive-diffractive element. Results show that both correctors can correct for Longitudinal Chromatic Aberration(LCA). However, it is demonstrated that the chromatic corrector with a single element introduces serious eccentric Transverse Chromatic Aberration (TCA) that increases from 14. 61μm to 81.4μm. This deteriorates the image quality at the edge field-of- view. On the chromatic eorreetor with two refractive-diffractive elements, both the LCA and the TCA can be corrected and the TCA is just 1.64μm. The designed chromatic corrector can be used to improve the retinal image quality and has potential applications in the design of visual instruments.
