复眼透镜在均匀照明中应用广泛，但是在大像差系统中其均匀性和能量利用率等性能会大大下降。通过对复眼透镜光束整形系统的成像假设，将其分解为若干子成像系统的组合，并讨论了像差及其表现对整形性能的影响。认为在像差表现中边缘点扩散、像面畸变、子孔径成像位置偏离对复眼透镜整形性能影响较大，而内部点扩散在一定程度上能够提高其整形性能。通过具体实例，控制对复眼透镜性能影响较大的像差表现而放宽影响较小的像差表现，优化设计以两个普通球面镜而不是通常采用的傅里叶透镜作为积分透镜的大像差复眼透镜整形系统，验证了该成像分析方法及其结果的有效性。

The fly′s eye integrator is widely applied in homogeneous illuminance, but its performance decreases dramatically when the aberration of the system is large. In order to study the effects of aberration, the fly′s eye integrator is supposed to be composed by some certain sub-imaging-systems. The point diagram of grim point, distortion and the departure of sub-image location caused by aberration can influence the performance of fly′s eye integrator seriously, but the point diagram of inner points can improve the performance to some extent. At last, an example, which optimizes a fly′s eye integrator made up of two ordinary lens rather than Fourier lens by limiting the derivative of aberration, is given and validates the effectiveness of the imaging analysis and its result.
