摘要：

Optical　sparse-aperture　system　can　be　designed　to　obtain　high　resolution　in　astronomical　object　imaging　with　several.　Maximal　and　minimum　fill　factors　of　the　sparse-aperture　systems　are　presented,　with　the　examples　of　annulus,　Golay6　and　tri-arm.　A　novel　model　named　sparse-aperture　multiple-array　system　is　also　proposed,　and　three　kinds　of　configuration　models　have　been　illustrated.　We　compare　the　imaging　performance　of　different　multiple-array　configurations　by　using　the　modulation　transfer　function　(MTF).　The　results　show　that　the　variety　of　space　between　sub-aperture　and　the　rotation　of　sub-array　of　multiple-array　configurations　have　the　effects　on　multiple-array　MTF,　and　the　multiple-array　configurations　have　the　advantages　of　firm　configuration　and　easy　fabrication.
