给出Golay3稀疏孔径光学系统的光瞳结构,分析其调制传递函数（MTF）特点。对不同填充因子的Golay3稀疏孔径光学系统模拟成像,并用几何均值滤波进行图像复原,以相关系数评价模拟成像质量和图像复原效果。结果表明：模拟成像和图像复原结果与调制传递函数分析结果一致;经几何均值滤波后,图像质量得到改善：图像复原效果随填充因子增大而提高。

The pupil of Golay3 sparse aperture optical system was presented and the features of its corresponding Modulation Transfer Function（MTF） were revealed.The imaging simulation with noise was implemented through Golay3 sparse aperture optical system with different fill factors.Then the noisy images were restored by geometric mean filter（GMG）.The image restoration effect was evaluated by correlation coefficient.The results indicated that the simulation imaging and images restoration accord with MTF analysis;the image restoration was effective and the quality of restored images was improved along with the raised fill factor.
