    The RMS values of wavefront aberrations shows that human eye’s wavefront aberrations increase with the increase of pupil diameter, the RMS values of Zernike 2-10 orders wavefront aberrations at 6mm and 5.2mm pupil diameters are 1.2-7.7 and 1.1-4.8 times larger than that at 3.1mm pupil diameter.
    波前像差的RMS值表明,随着瞳孔直径的增大,人眼各阶波前像差均随着增大。 与瞳孔直径为3.1mm时相比,瞳孔直径为6mm和5.2mm时,Zernike2-10阶波前像差的RMS值分别增大1.2-7.7倍和1.1-4.8倍。
    Imaging quality affected by high-order wavefront aberrations is evaluated through modulation transfer function (MTF) and Strehl ratio. The analysis shows that high-order aberrations at large pupil have more effect on the imaging quality than that at small pupil.
    用调制传递函数(MTF)和Strehl比评价了高阶波前像差对成像质量的影响,结果表明,大瞳孔高阶波前像差对成像质量的影响大于小瞳孔;
    To achieve Strehl ratio under diffraction limit, the orders of aberration to be corrected are pre2-4 orders, pre3-6 orders and pre5-7 orders of Zernike wavefront aberrations at 3.1mm, 4.1mm and 5.2mm pupil diameters, respectively. The orders of aberration to be corrected will increase with the increase of pupil diameter.
    在3.1mm,5.2mm和6mm瞳孔直径下,欲达到衍射极限的Strehl比率,分别需要矫正Zernike波前像差前2-4阶、前3-6阶和前5-7阶,需矫正的像差阶数随瞳孔直径的增大而增加。
