Multi-frame Sparse Aperture Image Restoration Based on Movable Array

摘要：

　　The modulation transfer function of optical sparse aperture system is attenuated among the low and middle frequency band,which causes the degradation and blur.Aimed at this problem,the Annulus array with six apertures is studied.Firstly,a half of its sub-apertures are moved towards center to respectively acquire the multi-frame images that contain integrated information.Secondly,the move scales are determined via the cut-off frequency and mid-band energy ratio.Finally,image restoration is performed by multi-frame iterative blind deconvolution algorithm.The experimental result shows that the proposed method works well on the sparse aperture image restoration of Annulus array while the reconstruction accuracy has also been validated.Moreover,the design of relative sensor can be innovated by this method.
