摘要：

人眼是一个不完善的成像系统，存在着各种像差，包括轴上像差及轴外像差, 这些像差都会影响视网膜的成像质量。而现阶段大多数人眼像差的检测方法主要针对轴上视场像差的测量，比如离焦、像散以及部分高阶像差的测量。因此提出了基于Hartmann-Shack波前传感器的人眼离轴像差的测量方法，建立测量系统并进行实验研究，当离轴角度从0°偏离到左右各5°、10°时，均方根（RMS）值分别从1.12变化到1.36（1.52），1.41（1.96），结果表明随着离轴角度的增加人眼外围视野的成像质量显著下降，原因一方面是人眼离轴像差的增大，另一方面是由于外围视野的感光细胞密度降低。

Abstract:

The human eye is an imperfect refractive system which has kinds of aberrations, including on-axis aberrations and off-axis aberrations, all of which have influence on the imaging quality of retina. But at present most of the ocular aberration detection methods focus on on-axis measurement, such as defocus, astigmatism, and part of high orders aberrations. The ocular off-axis aberrations detection method based on the Hartmann-Shack is proposed, the measuring system is set up and the experimental test is carried out. When the off-axis angle changes from 0° around to 5°, 10°, root mean square(RMS) values change from 1.12 to 1.36 (1.52), and 1.41 (1.96), and the results show that with the increase of the off-axis angle, the image quality of human peripheral vision decreased significantly. The reason is the increase of the off-axis aberrations, the other reason is due to the decrease of the peripheral vision photoreceptor cells density.
