Multi-aperture　telescope　is　proposed　to　achieve　high　angular　resolution　without　fabricating　a　large　diameter　monolithic　primary　mirror.　Due　to　the　array　structure,　the　multi-aperture　telescope　has　almost　the　same　cut-off　frequency　as　an　equivalent　diameter　telescope,　but　decrease　in　the　area　of　light　collecting,　which　is　the　reason　that　the　direct　output　image　of　multi-aperture　telescope　is　blurred　and　low　contrast.　The　additive　noise　level　is　another　reason　for　low　image　quality.　The　Wiener　filter　is　sensitive　to　noise　because　of　the　zero　value　out　of　the　cut-off　frequency　in　optical　transfer　function.　An　alternative　image　deblurring　method　is　total　variation　(TV)　blind　deconvolution.　The　TV　method　is　an　iterative　algorithm　and　preserves　the　edge　information　well.　The　most　important　characteristic　of　TV　blind　deconvolution　is　that　the　algorithm　is　still　working　with　high　noise　level　and　produces　reasonable　result.
