An　automatic　single-point　imaging　compressive　sampling　(CS)　system　was　developed　in　the　present　work　based　on　the　concept　of　manual　CS　system.　The　design　of　the　rotating　coding　disc　and　the　way　for　obtaining　the　information　of　coding　block　were　presented.　A　series　of　optimized　coding　blocks　were　used　as　sensing　matrix　and　the　minimum　mean　square　error　linear　estimate　(MMSE)　algorithm　was　employed　for　image　reconstruction.　The　quality　of　image　reconstruction　could　be　guaranteed　when　low　sample　rate　of　7.8%　was　used.　It　is　demonstrated　that　the　proposed　automatic　system　can　work　better　than　the　manual　one,　with　lower　error,　higher　efficiency　and　more　flexible　in　measurement　times.　©　2016,　Editorial　Board,　Journal　of　Applied　Optics.　All　right　reserved.
