Results: The refraction results of the Allegretto Wave Analyzer were very unstable. The spherical, cylinder diopter and the axis of the cylinder varied greatly. The refractive errors were large while the refractive errors were little by the subjective refraction examinations. During the wavefront examination, spots of the laser matrix were blurring, and the reproducibility was not good. Wavefront analyses showed that the Array pseudophakic eyes had relative large coma while the patients had no obvious symptoms.

研究结果：像差分析仪检测得的屈光度结果十分不稳定，球镜度、柱镜度、散光轴都变化很大，可重复性差，检测的屈光不正度数较大，而主觉验光时，患眼的屈光不正度数较低。5只眼的光学矩阵的测量点均非常模糊，且测量结果的可重复性较差，像差分析显示，Array人工晶状体有很大的第三阶彗差，但患者的自我感觉良好。

分析使用两个对称的单平凸透镜光路制作光栅并用MATLAB编写光线追迹程序分析了所制作的光栅的衍射波像差的特点，经计算得出在较小焦比D/F情况下其衍射波像差仅与两支光路点光源的调节偏差之差有关与单独的各个偏差无关；初级像差中球差很小几乎可忽略：彗差仅与垂轴调节偏差之差成线性关系；像散仅与轴向调节偏差之差成正比；且当平凸透镜的焦比D/F增大时，各像差项迅速增大。

Basic ideas for the design of a flat-field concave grating with three stigmatic points are proposed. As a proof of the usefulness of these design approaches, image conditions of the grating with three stigmatic points are developed which concise with other published results and they are more general than those obtained from holographic gratings.

aberration：像差

这就涉及到一个概念--像差(aberration),即屈光偏差的总称,包括球镜、柱镜等"低阶像差"以及球差、彗差等"高阶像差"(临床上的"不规则散光"),临床上像差通常特指"高阶像差".

chromatic aberration：色像差

光学基础知识:色像差(Chromatic aberration)与色散(Dispersion)轴向色像差涉及到成像的焦点距离,引起色彩产生松散或光斑(flare);而倍率色像差别则涉及到成像的大小,在画面周围引起色彩错开,形成扩散的彩色条纹,如镶边(fringing)现象.

spherical aberration：球像差
