Research on the simulation Experiment for the Sparse-aperture Optical System
Abstract:The sparse aperture configuration of Golay3 and its modulation transfer function (MTF) were analyzed. The idea of the experiment and the parameters of the experimental apparatus were introduced. The aperture configuration of the Golay3 was used in the optical system. The experimental images and their Wiener filtered images of the filled-aperture and the Golay3 sparse aperture were given out, and these results were compared with those of the simulating images. Through the comparison, it is shown that the experimental results consist with that of simulation imaging. The imaging theory of the sparse aperture optical system is verified. The Wiener filtering technique is effective while applied in the image recovering for the sparse aperture optical systems.
Keywords: space remote sensing, sparse- aperture, simulating experiment
