Ka noiʻi a me ka hoʻomohala ʻana o ka ʻenehana ʻike ultrasonic

ʻO ke kani kani kani ponoʻī

1. ʻenehana ʻike ultrasound laser

ʻO ka ʻenehana ʻike kani ultrasonic ʻo ka hoʻohana ʻana i ka laser pulsed e hana i ka pulse ultrasonic e ʻike i ka mea hana.Hiki i ka laser ke hoʻoulu i nā hawewe kani ultrasonic ma ka hana ʻana i kahi hopena elastic thermal a i ʻole ka hoʻohana ʻana i kahi mea waena.Hōʻike nui ʻia nā pono o ka ultrasound laser i ʻekolu mau ʻano:

(1) Hiki ke loaʻa ka lōʻihi lōʻihi, hiki i ka laser ultrasound ke lōʻihi lōʻihi ka hoʻolaha ʻana, ʻo ka attenuation i ke kaʻina hoʻolaha he liʻiliʻi;

(2) Hoʻopili pololei ʻole, ʻaʻole pono e hoʻopili pololei a kokoke paha i ka mea hana, kiʻekiʻe ka palekana ʻike;

(3) ʻO ka hoʻonā ʻike kiʻekiʻe.

Ma muli o nā pōmaikaʻi i luna, ʻoi aku ka maikaʻi o ka ʻike ultrasonic laser no ka ʻike ʻana i ka manawa maoli a me ka laina o ka mea hana ma kahi ʻano paʻakikī, a hōʻike ʻia nā hopena ʻike e ka wikiwiki ultrasonic scanning imaging.

Eia nō naʻe, loaʻa kekahi mau hemahema o ka ultrasound laser, e like me ka ʻike ultrasonic me ka hoʻonā kiʻekiʻe akā haʻahaʻa haʻahaʻa.No ka mea e pili ana ka ʻōnaehana ʻike i ka laser a me ka ʻōnaehana ultrasonic, ʻo ka ʻōnaehana ʻike ultrasonic ultrasonic piha ka nui i ka leo, paʻakikī i ke ʻano a me ke kumukūʻai kiʻekiʻe.

I kēia manawa, ke ulu nei ka ʻenehana ultrasound laser i ʻelua mau ʻaoʻao:

(1) Ka noiʻi hoʻonaʻauao ma ka laser ultrafast excitation mechanical a me ka pilina a me nā hiʻohiʻona microscopic o ka laser a me ka microscopic particles;

(2) Ka nānā 'ana i ka ho'onohonoho 'ana ma ka 'oihana.

2.Electromagnetic ultrasonic detection technology

ʻO ka hawewe kani ultrasonic Electromagnetic (EMAT) ka hoʻohana ʻana i ke ʻano hana induction electromagnetic e hoʻoulu a loaʻa i nā hawewe kani ultrasonic.Inā ho'oka'awale 'ia ka uila alapine ki'eki'e i loko o kahi pō'ai kokoke i ka ili o ka metala i ana 'ia, e loa'a ana ke au i ho'okomo 'ia o ka alapine like 'ole i ka metala ana.Inā hoʻohana ʻia kahi mānoanoa mau ma waho o ke metala i ana ʻia, e hoʻohua mai ke au i hoʻokomo ʻia i ka ikaika Lorentz o ka alapine like, e hana ana ma ka lattice metala i ana ʻia e hoʻāla i ka haʻalulu manawa o ke ʻano aniani o ka metala i ana ʻia, e hoʻoulu i nā hawewe kani ultrasonic. .

Hoʻokumu ʻia ka electromagnetic ultrasonic transducer me ka high-frequencycoil, waho magnetic field a me ke ana conductor.Ke hoʻāʻo nei i ka mea hana, komo pū kēia mau ʻāpana ʻekolu e hoʻopau i ka hoʻololi ʻana o ka ʻenehana kumu o ka ultrasound electromagnetic ma waena o ka uila, magnetism a me ke kani.Ma o ka hoʻoponopono ʻana i ka hoʻolālā coil a me ke kūlana hoʻonohonoho, a i ʻole ka hoʻoponopono ʻana i nā ʻāpana kino o ka coil kiʻekiʻe-frequency, E hoʻololi i ke kūlana ikaika o ka conductor i hoʻāʻo ʻia, pēlā e hana ai i nā ʻano ʻano ultrasound.

3.ʻenehana ʻike ultrasound i hui pū ʻia e ka ea

ʻO ka ʻenehana ʻike kani ultrasonic hui pū ʻia he ʻano hoʻāʻo nondestructive ultrasonic non-contact hou me ka ea e like me ke ʻano hui.ʻO nā mea maikaʻi o kēia ʻano hana ʻaʻole pili, non-invasive, a ʻaʻole luku loa, e pale ana i kekahi mau hemahema o ka ʻike ultrasound maʻamau.I nā makahiki i hala iho nei, ua hoʻohana nui ʻia ka ʻenehana ʻike kani ultrasonic i hoʻohui ʻia i ka ʻike hemahema o nā mea i hoʻohui ʻia, loiloi hana waiwai, a me ka ʻike ʻakomi.

I kēia manawa, ka noiʻi o kēia ʻenehana nui ka nānā ʻana i nā hiʻohiʻona a me ke kumumanaʻo o ka hui ʻana o ka ea excitation ultrasonic mahina, a me ka noiʻi ʻana o ka hana kiʻekiʻe a me ka haʻahaʻa haʻahaʻa ea hui pū.Hoʻohana ʻia ka COMSOL multi-physical field simulation software e hoʻohālike a hoʻohālikelike i ke kahua kani ultrasonic i hoʻohui ʻia e ka ea, i mea e nānā ai i nā hemahema qualitative, quantitative a me nā kiʻi i loko o nā hana i nānā ʻia, e hoʻomaikaʻi ai i ka pono ʻike a hāʻawi i ka ʻimi pono no ka noi pono. o ka ultrasound pili ole.

E aʻo i ka ʻenehana kōkua ultrasound

ʻO ka noiʻi ʻenehana kōkua ultrasound e pili nui ana iā ia ma ke kumu o ka hoʻololi ʻole ʻana i ke ʻano ultrasound a me ke kumu, ma ke kumu o ka hoʻohana ʻana i nā ʻano ʻenehana ʻē aʻe (e like me ka loaʻa ʻana o ka ʻike a me ka ʻenehana hana, ka ʻenehana hana kiʻi, ka ʻenehana naʻauao hana, etc.) , ka ʻenehana o nā ʻanuʻu ʻike kani ultrasonic (ka loaʻa ʻana o ka hōʻailona, ​​ka nānā ʻana i ka hōʻailona a me ka hoʻoili ʻana, ke kiʻi defect) optimization, i mea e loaʻa ai nā hopena ʻike pololei.

1.Nerual network technology

ʻO ka neural network (NNs) kahi hiʻohiʻona makemakika algorithmic e hoʻohālike i nā hiʻohiʻona ʻano o nā NN holoholona a hana i ka hoʻoili ʻike ʻike like ʻole.Hoʻopili ka pūnaewele i ka paʻakikī o ka ʻōnaehana a hoʻokō i ke kumu o ka hoʻoponopono ʻana i ka ʻike ma o ka hoʻoponopono ʻana i nā pilina ma waena o ka nui o nā nodes.

2.ʻenehana kiʻi 3 D

Ma ke ʻano he alakaʻi hoʻomohala koʻikoʻi o ka hoʻomohala ʻana i ka ʻenehana kōkua ultrasonic detection, 3 D imaging (Three-Dimensional Imaging) ʻenehana i hoʻokomo pū i ka manaʻo o nā haumāna he nui i nā makahiki i hala.Ma ka hōʻike ʻana i ke kiʻi 3D o nā hopena, ʻoi aku ka kikoʻī a me ka intuitive nā hopena ʻike.
