1. Te kaupapa mahi okaiwhakarerekētanga oro-whatu
Ko te uho o te pūwhakarerekētanga acousto-whatu (Kaiwhakarerekētanga AOM)ko te pānga acousto-whatu. Kei roto i tōna hanganga taketake ngā tioata acousto-whatu, ngā transducers, ngā taputapu mimiti, me ngā taraiwa. Ka hurihia te tohu hiko e puta mai ana i te taraiwa hei ngaru ultrasonic e te transducer. Ina horapa ngā ngaru ultrasonic i roto i te reo acousto-whatu, ka puta he huringa auau i roto i te kiato reo, ka hanga he hanganga e rite ana ki te kupenga ā-wāhanga. Ina haere te mārama i roto i tēnei reo, ka puta te diffraction, ka tutuki ai te whakarerekētanga o te ngaru kawe whatu. E rua ngā momo aratau diffraction matua: te diffraction Raman Ness me te diffraction Bragg. Ko te modulator AOM e whakamahia whānuitia ana ka mahi i roto i te aratau diffraction Bragg, kei reira te mārama taunga mai ka taunga mai i tētahi koki Bragg motuhake, ā, kei roto i te mārama putanga te mārama kore-raupapa kāore i te whakaatahia me te mārama diffraction tuatahi-raupapa me te koki whakapohehe.
2. Ngā tawhā hangarau matua o te modulator acousto-whatu
2.1 Te whai huatanga o te whakawhitiwhiti me te ngaronga o te whakarerekētanga: e ine ana i te kaha o tētahi taputapu ki te huri i te mārama taunga mai ki te mārama whakawhitiwhiti o te raupapa tuatahi me te ngaronga whatu e haere tahi ana.
2.2 Koki Bragg: Ko te koki taunga motuhake e tutuki ai te pai o te whai huatanga o te diffraction, e pā ana ki te roanga ngaru taiaho, te auau reo irirangi, me te tere oro i roto i te karaihe.
2.3 Mana RF tino pai: arā, mana kōtui, te mana taraiwa RF e hiahiatia ana hei whakatutuki i te whai huatanga whakarara mōrahi. Kei roto i te tuhinga te tātai tatau motuhake.
2.4 Te urutau ki te koki rerekētanga: Hei whakarite i te mahi tino pai, me ōrite te koki rerekētanga o te taiaho taunga ki ngā āhuatanga o te reo acousto-whatu.
2.5 Te tere whakarerekētanga: e tohuhia ana e te wā pikinga o te mārama, i runga i te wā tuku o ngā ngaru oro mā roto i te hihi, ā, e pā ana ki te whānui o te hihi me te tere o te oro.
3. Ngā tono matua o ngā modulators acousto-whatu
Ngā tono matua e rima ohangarau ā-oro-whatuko:
3.1 Pana-Q whatu oro: ka whakanohoia ki roto i te kōhao taiaho, ka whakaputa i te taiaho pupuhi mana teitei mā te whakarerekē tere i ngā ngaronga kōhao.
3.2 Pūwhakarerekē/pana whatu oro: e whakamahia ana mō te whakarerekētanga kaha, te whakahaere tere rānei i te whakakā-whakaweto o te taiaho i waho o te kōhao taiaho, ā, ka taea te whakamahi hei kati, hei whakaiti rānei i te kanapa.
3.3 Ārai whatu oro: Mā te whakarerekē i te auau reo irirangi hei ārai i te hihi taiaho, ka tutuki te matawai hihi tere, he mea tika mō te urunga matapōkere, te matawai tonu rānei.
3.4 Whakawhiti auau whatu oro: he mea hanga motuhake hei neke i te auau taiaho ki runga, ki raro rānei, ā, ka taea te whakarārangi kia tutuki ai ngā huinga whakawhiti auau uaua ake.
3.5 Tātari Āhua Āhua Acousto: He tātari āhua hiko ā-totoka ka taea te whiriwhiri tere me te hihiri i ngā roangaru motuhake mai i te whānuitanga o te whānuitanga.pūtake mārama.
