The　optical　sparse　aperture　system　achieves　almost　the　same　resolution　as　a　conventional　full　filled　aperture　telescope　but　with　a　lower　weight　and　cost.　However,　the　greatly　reduced　modulation　transfer　function　(MTF)　causes　significant　blurring　and　loss　of　contrast　in　the　observed　image.　The　image　restoration　algorithms　can　correct　the　blurring　if　the　actual　optical　transfer　function　(OTF)　or　point　spread　function　(PSF)　is　given.　Usually,　the　OTF　and　PSF　captured　by　experiment　is　assumed　to　be　the　actual　OTF　and　PSF,　which　are　considered　as　the　best　match　for　image　restoration.　However,　the　noise　contained　within　the　captured　PSF　or　OTF　may　prevent　successful　restoration.　Here,　we　investigate　the　restored　image　by　the　captured　PSF　and　the　calculated　PSF　based　on　array　configuration.　The　calculated　PSF　produced　a　better　result　than　the　captured　PSF.
