Two models of the image restoration for sparse aperture optical systems are proposed.The adapted condition is analysed about Wiener filtering,least squares filtering and MLE blind deconvolution.According to the experiment,the issue points out Wiener filtering and least squares filtering use camara lens′ OTF as the whole system MTF.In theory the Wiener filtering can make the best image restoration.Considering sparse aperture optical systems with noises,the blind deconvolution uses the atmosphere transfer function and the lens′ OTF as the system MTF to have a image restoration.The result is better than Wiener filtering using constant K and least squares filtering.
