He tirohanga whānui mō ngā pūwhakatikatika noa e whā

E whakaatu ana tēnei pepa i ngā tikanga whakarerekētanga e whā (te whakarerekē i te kaha o te taiaho i roto i te rohe wā nanohekona, subnanohekona rānei) e whakamahia whānuitia ana i roto i ngā pūnaha taiaho muka. Kei roto i ēnei ko te AOM (whakarerekētanga acousto-whatu), te EOM (whakarerekētanga electro-whatu), te SOM/SOA(te whakanui i te mārama o te haurua-arataki e mōhiotia ana ko te whakarerekētanga haurua-arataki), mewhakarerekētanga taiaho tikaI roto i a rātou, ko AOM,EOM,nō roto te SOM i te whakarerekētanga ā-waho, i te whakarerekētanga ā-kore rānei.

1. Pūwhakarerekētanga Oro-whatu (AOM)

Ko te whakarerekētanga ā-tinana oro-whatu he tukanga ā-tinana e whakamahi ana i te pānga oro-whatu hei uta i ngā mōhiohio ki runga i te kaikawe whatu. I te whakarerekētanga, ka whakamahia tuatahitia te tohu hiko (te whakarerekētanga whānui) ki te whakawhiti hiko-oro, e huri ai te tohu hiko ki te mara ultrasonic. Ina pā te ngaru mārama mā roto i te reo oro-whatu, ka whakarerekētia te kaikawe whatu, ā, ka huri hei ngaru whakarerekētanga kaha e kawe ana i ngā mōhiohio nā te mahi oro-whatu.

2. Kaiwhakarerekētanga Hiko-whatu(EOM)

Ko te kaiwhakatikatika hiko-whatu he kaiwhakatikatika e whakamahi ana i ngā pānga hiko-whatu o ētahi tioata hiko-whatu, pērā i ngā tioata lithium niobate (LiNb03), ngā tioata GaAs (GaAs) me ngā tioata lithium tantalate (LiTa03). Ko te pānga hiko-whatu, ina pāngia te ngaohiko ki te tioata hiko-whatu, ka huri te taupū whakaata o te tioata hiko-whatu, ka hua ake he huringa ki ngā āhuatanga o te ngaru mārama o te tioata, ā, ka tutuki te whakarerekētanga o te āhua o te tohu whatu, te kaha, te kaha me te pōraritanga.

Pikitia: Whirihoranga noa o te ara iahiko taraiwa EOM

3. Kaiwhakarerekē Whatu Ārahi/Whakakaha Whatu Ārahi (SOM/SOA)

Ko te whakakaha whatu haurua-whakahaere (SOA) e whakamahia ana mō te whakakaha tohu whatu, he painga nōna ko te maramara, te iti o te kai hiko, te tautoko mō ngā roopu katoa, me ētahi atu, ā, he huarahi kē atu mō ngā whakakaha whatu tuku iho pērā i te EDFA (Whakakaha muka kua tāpirihia ki te erbium). He rite tonu te taputapu o te kaiwhakatikatika whatu haurua-haurua (SOM) ki te whakakaha whatu haurua-haurua, engari he rerekē te whakamahinga i tōna whakamahinga me te whakakaha SOA tuku iho, ā, he rerekē ngā tohu e arotahi ana ina whakamahia hei kaiwhakatikatika mārama i ērā e whakamahia ana hei whakakaha. Ina whakamahia mō te whakakaha tohu whatu, ka whakaratohia he iahiko taraiwa pumau ki te SOA hei whakarite kia mahi te SOA i te rohe raina; Ina whakamahia hei whakatikatika i ngā pāoro whatu, ka whakauru i ngā tohu whatu tonu ki te SOA, ka whakamahi i ngā pāoro hiko hei whakahaere i te iahiko taraiwa SOA, kātahi ka whakahaere i te āhua putanga SOA hei whakakaha/whakaiti. Mā te whakamahi i ngā āhuatanga whakakaha me te whakaiti SOA, kua āta whakamahia tēnei aratau whakatikatika ki ētahi tono hou, pērā i te pūoko muka whatu, te LiDAR, te whakaahua hauora OCT me ētahi atu mara. Ina koa mō ētahi āhuatanga e hiahia ana kia nui te rōrahi, te kai hiko me te ōwehenga mate.

4. Ka taea hoki e te whakarerekētanga tika o te taiaho te whakarerekē i te tohu whatu mā te whakahaere tika i te iahiko rītaha, e whakaaturia ana i te pikitia i raro nei, ka whiwhihia he whānui o te pāoro 3 nanohekona mā te whakarerekētanga tika. Ka kitea he pīka i te tīmatanga o te pāoro, ka puta mai i te whakangā o te kawe taiaho. Ki te hiahia koe ki te whiwhi pāoro o te 100 pikohekona, ka taea e koe te whakamahi i tēnei pīka. Engari i te nuinga o te wā kāore mātou e hiahia ki tēnei pīka.

Whakarāpopototanga

He pai te AOM mō te putanga mana whatu i roto i te torutoru watts, ā, he mahi nekehanga auau tōna. He tere te EOM, engari he nui te uaua o te taraiwa, ā, he iti te ōwehenga whakamōmona. Ko te SOM (SOA) te otinga tino pai mō te tere GHz me te ōwehenga whakamōmona teitei, me te iti o te kai mana, te whakaiti me ētahi atu āhuatanga. Ko ngā taiaho taiaho tika te otinga iti rawa, engari kia tūpato ki ngā huringa o ngā āhuatanga hihi. He painga me ngā ngoikoretanga o ia kaupapa whakarerekētanga, ā, he mea nui kia mārama tika ki ngā whakaritenga tono i te wā e whiriwhiri ana i tētahi kaupapa, me te mōhio ki ngā painga me ngā ngoikoretanga o ia kaupapa, me te whiriwhiri i te kaupapa tino tika. Hei tauira, i roto i te pūoko muka tohatoha, ko te AOM tuku iho te mea matua, engari i roto i ētahi hoahoa pūnaha hou, kei te tere haere te whakamahinga o ngā kaupapa SOA, i roto i ētahi kaupapa tuku iho liDAR hau e whakamahi ana i te AOM e rua-wāhanga, ko te hoahoa kaupapa hou hei whakaiti i te utu, hei whakaiti i te rahi, me te whakapai ake i te ōwehenga whakamōmona, ka whakamahia te kaupapa SOA. I roto i te pūnaha whakawhitiwhiti kōrero, ko te pūnaha tere iti te tikanga e whakamahi ana i te kaupapa whakarerekētanga tika, ā, ko te pūnaha tere teitei te tikanga e whakamahi ana i te kaupapa whakarerekētanga hiko-whatu.
