Te rangahau me te ahunga whanaketanga o te hangarau kitenga ultrasonic

Na te tere o te whakawhanaketanga o nga momo mara, kei te whanake tere hoki te hangarau rapu ultrasonic. Ko te hangarau whakaahua, te hangarau o te waahanga, te hangarau raupapa 3D, te hangarau whatunga neural artificial (ANNs), te hangarau ngaru arahina ultrasonic kua pakari haere, e whakatairanga ana i te whanaketanga o te hangarau rapu ultrasonic.

I tenei wa, ka whakamahia te whakamatautau ultrasonic i roto i te hinu, te maimoatanga hauora, te ahumahi karihi, te aerospace, te kawe, te miihini me etahi atu ahumahi. Ko te ahunga whanaketanga rangahau a meake nei mo te hangarau rapu ultrasound te nuinga o nga waahanga e rua e whai ake nei:

Te rangahau me te ahunga whanaketanga o te hangarau kitenga ultrasonic

Ultrasound ake rangahau hangarau

(1) Te rangahau me te whakapai ake i te hangarau ultrasound ake;

(2) Te rangahau me te whakapai ake i te hangarau awhina ultrasound.

Ultrasound ake rangahau hangarau

1. Hangarau whakakitenga ultrasound taiaho

Hangarau taiaho ultrasonic detection he ki te whakamahi i te taiaho pulsed ki te whakaputa i te pulse ultrasonic ki te kitea te mahi. Ka taea e te taiaho te whakaihiihi i nga ngaru ultrasonic ma te whakaputa i te paanga elastic waiariki, te whakamahi ranei i tetahi rauemi takawaenga. Ko nga painga o te ultrasound laser e whakaatuhia ana i roto i nga waahanga e toru:

(1) Ka taea te rapu tawhiti, ka taea e te ultrasound laser te whakatö tawhiti roa, he iti te attenuation i roto i te tukanga whakatö;

(2) Ko te whakapiri kore-tika, kaua e hiahia ki te whakapiri tika, ki te tata ranei ki te taputapu mahi, he nui te haumaru o te kitenga;

(3) Taumira kitenga teitei.

I runga i nga painga o runga ake nei, he tino pai te kitenga o te taiaho ultrasonic mo te wa-a-ipurangi me te waahi-a-ipurangi o te taputapu mahi i roto i te taiao kino, a ko nga hua o te kitenga ka whakaatuhia e te tere o te whakaahua matawai ultrasonic.

Heoi ano, he maha nga ngoikoretanga o te ultrasound laser, penei i te kitenga ultrasonic me te taumira teitei engari he iti noa iho. No te mea ko te punaha whakakitenga e uru ana ki te punaha laser me te punaha ultrasonic, he nui te rahi o te punaha whakakitenga laser laser, he uaua te hanganga me te utu nui.

I tenei wa, kei te whanake te hangarau ultrasound laser i nga huarahi e rua:

(1) Te rangahau maatauranga mo te miihini whakaihiihi ultrafast laser me te taunekeneke me nga ahuatanga miihini o te laser me nga matūriki miihini;

(2) Aroturuki tūnga ipurangi i roto i te ahumahi.

2.Hangarau whakakitenga ultrasonic hiko

Ko te ngaru ultrasonic electromagnetic (EMAT) ko te whakamahinga o te tikanga whakauru hiko ki te whakaongaonga me te whiwhi ngaru ultrasonic. Mena ka tohatohahia te hiko auau teitei ki roto i te porowhita e tata ana ki te mata o te konganuku ine, ka puta he ia o te aurere rite tonu ki te whakarewa ine. Mēnā ka tukuna he āpure autō i waho o te whakarewa ine, ka puta he kaha Lorentz he rite tonu te auau, ka mahi i runga i te kupenga whakarewa ine hei whakaoho i te wiri o te hanganga karaihe o te whakarewa ine, hei whakaongaonga i nga ngaru ultrasonic. .

Ko te transducer ultrasonic electromagnetic he mea tito ki te high-frequencycoil, te papa autō o waho me te kaikawe ine. I te wa e whakamatautau ana i te taputapu mahi, ka uru tahi enei waahanga e toru ki te whakaoti i te huringa o te hangarau matua o te ultrasound electromagnetic i waenga i te hiko, te aukume me te tangi. Na roto i te whakarereketanga o te hanganga porowhita me te tuunga tuunga, te whakarereketanga ranei o nga tawhā tinana o te coil teitei-auau, Ki te huri i te ahuatanga kaha o te kaikawe kua whakamatauria, na reira ka whakaputa i nga momo rereke o te ultrasound.

3.Hangarau whakakitenga ultrasound hono-rangi

Ko te hangarau kitenga ultrasonic hono-kore he tikanga whakamatautau kore-whakapaa ultrasonic hou me te hau hei reo hono. Ko nga painga o tenei tikanga ko te kore-whakapaa, kaore i te whakaeke, me te tino kore-whakangaro, te karo i etahi huakore o te kitenga ultrasound tuku iho. I nga tau kua pahure ake nei, kua whakamahia whanuitia te hangarau rapu ultrasonic honohono-rangi i roto i te rapunga koha o nga rauemi hiato, te arotake mahi rauemi, me te kitenga aunoa.

I tenei wa, ko te rangahau o tenei hangarau te nuinga e aro ana ki nga ahuatanga me te ariā o te hau hono o te hau whakakorikori mara ultrasonic, me te rangahau o te kakama teitei me te iti o te haruru o te haruru hau e hono ana. Ko te COMSOL maha-a-tinana te rorohiko whaihanga mara e whakamahia ana ki te whakatauira me te whakatauira i te mara ultrasonic kua honoa e te hau, kia rite ki te tātari i nga hapa o te kounga, te ine me te whakaahua i roto i nga mahi kua tirotirohia, e whakapai ake ana i te pai o te kitenga me te whakarato i te torotoro whai hua mo te whakamahinga mahi. o te ultrasound kore-whakapā.

Te rangahau mo te hangarau awhina ultrasound

Ko te rangahau hangarau awhina i te ultrasound te nuinga e pa ana ki a ia i runga i te kore e whakarereke i te tikanga me te kaupapa o te ultrasound, i runga i te whakamahi i etahi atu waahanga o te hangarau (penei i te whiwhi korero me te hangarau tukatuka, hangarau hanga whakaahua, hangarau mohio, me etahi atu). , te hangarau o nga hikoi kitenga ultrasonic (te whiwhi tohu, te tātari tohu me te tukatuka, te whakaahua hapa) arotautanga, kia pai ake ai nga hua kitenga.

1.Nhangarau whatunga erualpūtaiao

Ko te whatunga neural (NNs) he tauira pangarau algorithmic e whakataurite ana i nga ahuatanga whanonga o nga NN kararehe me te mahi tukatuka korero whakarara kua tohatohahia. Ko te whatunga kei runga i te uaua o te punaha me te whakatutuki i te kaupapa o te tukatuka korero ma te whakatika i nga hononga i waenga i te maha o nga pona.

2.Hangarau whakaahua 3 D

Ko te ahunga whanaketanga nui o te whanaketanga hangarau awhina te kitenga ultrasonic, ko te hangarau 3 D (Three-Dimensional Imaging) kua arohia e te maha o nga tohunga i nga tau tata nei. Ma te whakaatu i te atahanga 3D o nga hua, he tino motuhake, he maamaa hoki nga hua kitenga.
