A　double-turn　coil　omnidirectional　shear-horizontal　wave　magnetostrictive　patch　transducer　(DC-OSH-MPT)　array　for　imaging　detection　in　composite　plates　is　presented.　DC-OSH-MPT　parameters　are　optimized　in　order　to　make　the　transducer　more　suitable　for　imaging　detection.　Besides,　the　characteristic　of　the　lowest　shear-horizontal　mode　(SH0),　which　can　be　generated　and　received　in　all　directions　by　DC-OSH-MPT　bonded　on　composite　plate,　is　beneficial　for　imaging.　Due　to　anisotropic　property　of　composite　plates,　the　group　velocity　of　SH0　mode　in　different　azimuthal　directions　was　experimentally　measured　in　damage　imaging.　The　location　of　simulated　damage,　which　was　a　bonded　circular　cylinder,　was　estimated　by　DC-OSH-MPT　array　and　ellipse　imaging　algorithm.　The　imaging　results　have　demonstrated　that　DC-OSH-MPT　can　be　considered　as　a　spatially　distributed　array　suitable　for　imaging　detection　in　composite　plates.
