Pūwhakarerekētanga oro-whatuTe whakamahinga i roto i ngā kāpata atomu makariri
Hei wāhanga matua o te hononga taiaho muka-katoa i roto i te kāpata ngota makariri, ko tepūwhakarerekētanga muka whatu acousto-whatuka whakarato i te taiaho pūmau-auau kaha-teitei mō te kāpata ngota makariri. Ka mimitihia e ngā ngota ngā irahiko me te auau oro o te v1. Nā te mea he rerekē te nekehanga o ngā irahiko me ngā ngota, ka heke te tere o ngā ngota i muri i te mimiti i ngā irahiko, ā, ka tutuki ai te kaupapa o te whakamatao i ngā ngota. Ko ngā ngota whakamatao-taiaho, me ō rātou painga pēnei i te wā tirotiro roa, te whakakorenga o te nekehanga auau Doppler me te nekehanga auau i puta mai i te tukinga, me te hononga ngoikore o te mara mārama kitenga, ka whakapai ake i te kaha ine tika o ngā irahiko ngota, ā, ka taea te whakamahi whānui i roto i ngā karaka ngota makariri, ngā inenga ngota makariri, me te whakatere ngota makariri, me ētahi atu mara.
Ko te roto o te AOM acousto-whatu muka whatu he mea hanga nui ki te karaihe acousto-whatu me te muka whatu collimator, me ētahi atu. Ka mahi te tohu whakarerekē ki te transducer piezoelectric i roto i te ahua o te tohu hiko (te whakarerekētanga whānui, te whakarerekētanga ā-wāhanga, te whakarerekētanga auau rānei). Mā te whakarerekē i ngā āhuatanga whakauru pēnei i te auau me te whānui o te tohu whakarerekētanga whakauru, ka tutuki te auau me te whānui o te taiaho whakauru. Ka hurihia e te transducer piezoelectric ngā tohu hiko ki ngā tohu ultrasonic e rerekē ana i te tauira kotahi nā te pānga piezoelectric, ā, ka horahia i roto i te reo acousto-whatu. I muri i te whakarerekētanga o te taupū whakaata o te reo acousto-whatu i ia wā, ka hangaia he whatanga taupū whakaata. Ina haere te taiaho mā roto i te muka whakaata, ā, ka tomo ki te reo acousto-whatu, ka puta te diffraction. Ka taupatupatu te auau o te mārama diffraction i te auau ultrasonic ki runga i te auau taiaho whakauru taketake. Whakatikatikahia te tūranga o te muka whakaata kia pai ai te mahi a te muka whakaata acoust-whatu muka whatu i te āhua pai rawa atu. I tēnei wā, me tutuki i te koki taunga o te hihi mārama taunga te tikanga titahatanga Bragg, ā, ko te aratau titahatanga ko te titahatanga Bragg. I tēnei wā, tata katoa te kaha o te mārama taunga ka whakawhitia ki te mārama titahatanga o te raupapa tuatahi.
Ko te AOM acuto-optic modulator tuatahi e whakamahia ana i te pito o mua o te whakakaha whatu o te pūnaha, e whakarerekē ana i te mārama whakauru tonu mai i te pito o mua me ngā pāoro whatu. Kātahi ka tomo ngā pāoro whatu kua whakarerekētia ki te kōwae whakakaha whatu o te pūnaha hei whakakaha pūngao. Ko te tuaruaAOM acuto-whatu whakarerekētangae whakamahia ana i te pito o muri o te whakakaha whatu, ā, ko tana mahi he wehe i te haruru taketake o te tohu pāoro whatu i whakakahangia e te pūnaha. Ko ngā taha o mua me muri o ngā pāoro mārama e tukuna ana e te AOM acouto-whatu tuatahi ka tohatoha ōrite. I muri i te urunga ki te whakakaha whatu, nā te mea he teitei ake te whakanui o te whakakaha mō te taha mua o te pāoro i tērā mō te taha muri o te pāoro, ka whakaatu ngā pāoro mārama kua whakakaha i tētahi āhuatanga whakapōturi āhua ngaru kei reira te pūngao e kukū ana ki te taha o mua, e whakaaturia ana i te Pikitia 3. Kia taea ai e te pūnaha te whiwhi pāoro whatu me te tohatoha ōrite i ngā taha o mua me muri, me whakamahi te AOM acouto-whatu tuatahi i te whakakaha ā-ira. Ka whakatikatika te waeine whakahaere pūnaha i te taha piki o te AOM acouto-whatu tuatahi hei whakanui ake i te taha piki o te pāoro whatu o te kōwae acoust-whatu me te utu mō te kore-ōrite o te whakanui o te whakakaha whatu i ngā taha o mua me muri o te pāoro.
Ehara i te mea ka whakanui noa te whakakaha whatu o te pūnaha i ngā tohu pāoro whatu whai hua, engari ka whakanui anō hoki i te haruru taketake o te raupapa pāoro. Hei whakatutuki i te ōwehenga tohu-ki-haruru teitei o te pūnaha, ko te āhuatanga ōwehenga mate tiketike o te muka whatuKaiwhakarerekētanga AOMKa whakamahia hei pehi i te haruru turanga i te pito o muri o te whakakaha, kia mōhio ai ka taea e ngā pāoro tohu pūnaha te haere pai i roto i te whānuitanga nui rawa atu, me te ārai i te haruru turanga kei uru ki te kati acousto-whatu rohe-wā (te kuaha pāoro rohe-wā). Ka whakamahia te tikanga whakarerekētanga mamati, ā, ka whakamahia te tohu taumata TTL hei whakahaere i te whakakā me te whakaweto o te kōwae acoust-whatu kia mōhio ai ko te taha piki o te pāoro rohe-wā o te kōwae acoust-whatu ko te wā piki kua hoahoatia o te hua (arā, ko te wā piki iti rawa ka taea e te hua te whiwhi), ā, ko te whānui o te pāoro e whakawhirinaki ana ki te whānui o te pāoro o te tohu taumata TTL pūnaha.
