摘　　要：分析Golay3稀疏孔径结构及其调制传递函数分布,介绍模拟实验平台构建的思路和实验装置的参数。给出全孔径和Golay3稀疏孔径两种光瞳的模拟实验像,以及进行维纳滤波图像处理,并与计算机模拟成像结果进行比较。结果表明模拟实验与计算机模拟成像一致,验证了稀疏孔径光学系统成像理论和维纳滤波技术应用于稀疏孔径光学系统图像复原的有效性。The sparse aperture configuration of Golay3 and its modulation transfer function（MTF） are analyzed.The idea of the experiment and the parameters of the experimental apparatus are introduced.The aperture configuration of the Golay3 is used in the optical system.Experimental images and their Wiener filtered images of the filled-aperture and the Golay3 sparse aperture are given out,and these results are compared with those of the simulating images by the computer.Through the comparison,it is shown that the experimental results consist with those of the computer simulating. The imaging theory of sparse aperture optical systems is verified. The Wiener filtering technique is effective while applied in the image recovering for sparse aperture optical systems.
