空域中，主要利用维格纳分布函数的正则投影来分析系统的点扩展函数对离焦像差的变化不敏感特性；频域中，则利用考纽螺线的图解方法来分析系统的光学传递函数对离焦像差的变化不敏感特性。

The eyes were periodically examined by retinoscopy, and A-scan ultrasonography. Two weeks later, the eyeballs were removed and the apoptotic cells were determined by electron microscopy, TUNEL technique and flow cytometry in scleras. Both bFGF and the bcl-2 protein were determined by the immunohistochemisty method and the Western-blot method. Results: All eyes treated with -10.00D or -20.00D concave lens produced defocus-induced myopia.

如果是蛋型的，那么焦内焦外看起来是一样的。

A new method for depth from defocus images is proposed.

提出了一种基于散焦图像计算景物距离的新方法。

In the article the reason of defocus is analyzed,and the influence of the defocus on the optical measurement is analyzed quantitatively by experiment.

When one element of an N-element array is aberrated, the most sensitive aberration is Piston error, and then the sensitive aberrations are element defocus, tilt, spherical aberration, coma and astigmatism. As for four aperture system, the influence of Piston error is 2 times larger than that of defocus, and 4 times larger than that of astigmatism.

在合成孔径成像系统单个子孔径存在像差的情况下，Piston误差对系统的影响最大，其次是离焦误差、倾斜误差、球差、彗差和像散，对于四孔径系统，Piston误差对系统的影响几乎是离焦误差的2倍，像散的4倍。
