Te whakarōpūtanga me te kaupapa whakarerekētanga o te whakarerekētanga taiaho
Kaiwhakarerekē taiahohe momo wāhanga taiaho whakahaere, ehara i te mea taketake pērā i ngā tioata, ngā karāhe arotahi me ētahi atu wāhanga, kāore hoki i te tino whakauru pērā i ngā taiaho,taputapu taiaho, he taumata teitei o te whakaurunga, ngā momo me ngā mahi o ngā hua o te akomanga taputapu. Mai i te whakaaturanga matatini o te ngaru mārama, ka kitea ko ngā āhuatanga e pā ana ki te ngaru mārama ko te kaha A(r), te wāhanga Φ(r), te auau ω me ngā āhuatanga e whā o te ahunga horapa, mā te whakahaere i ēnei āhuatanga ka taea te whakarerekē i te āhua o te ngaru mārama, ko te kaiwhakatikatika taiaho e rite ana ko tete whakarerekētanga kaha, te whakarerekētanga ā-wāhanga, te whakawhiti auau me te whakawhiti.
1. Kaiwhakarerekētanga kaha: e whakamahia ana hei whakarerekē i te kaha, i te whānui rānei o te taiaho, ko ngā mea tino kitea ko ngā whakaiti whatu, ko ngā kēti whatu, tae atu ki ngā taputapu me ngā taputapu whakauru pēnei i ngā wehewehe wā, ngā whakaū mana, me ngā whakaiti haruru.
2. Kaiwhakarerekētanga wāhanga: e whakamahia ana hei whakahaere i te āhua o te hihi, ko te pikinga āhua ka kiia ko te whakaroa, ko te hekenga āhua ka kiia ko te mata. He maha ngā momo whakarerekētanga āhua, ā, he rerekē rawa ngā mātāpono mahi, pērā i ngā whakarerekētanga whakaahua-pēkepeke, ngā whakarerekētanga āhua hiko-whatu tere-teitei LN, ngā pepa whakaroa āhua rerekē tioata wai, me ētahi atu, he whakarerekētanga āhua katoa i runga i ngā mātāpono mahi rerekē.
3. Whakawhiti auau: e whakamahia ana hei whakarerekē i te auau o ngā ngaru mārama, e whakamahia whānuitia ana i roto i ngā pūnaha taiaho teitei, i ngā taputapu mahere rānei, me te whakawhiti auau acousto-optical hei tohu noa.
4. Pūwhakarerekē: e whakamahia ana hei whakarerekē i te ahunga o te horapa o te hihi, ko te pūnaha galvanometer tikanga tētahi o aua pūnaha, hei tāpiri atu ki te galvanometer mems tere ake, te pūwhakarerekē hiko-whatu me te pūwhakarerekē acousto-whatu.
He ariā whānui tā mātou mō te pūwhakatikatika taiaho, arā, ko ngā wāhanga ka taea te whakahaere me te whakarerekē i ētahi āhuatanga ā-tinana o te taiaho, engari e hiahia ana ki te whakauru katoa i ngā hua motuhake o te pūwhakatikatika taiaho, kāore i te rawaka tētahi tuhinga. Nō reira, tuatahi, arotahi ki te pūwhakatikatika kaha. Ko te pūwhakatikatika kaha he momo pūwhakatikatika e whakamahia whānuitia ana i roto i ngā momo pūnaha whatu katoa, ko tōna momo, ko ōna mahi rerekē ka taea te whakaahua he uaua, i tēnei rā ka whakaatuhia e mātou ngā kaupapa pūwhakatikatika kaha e whā: te kaupapa miihini, te kaupapa hiko-whatu, te kaupapa acousto-whatu me te kaupapa karaihe wai.
1. Kaupapa Ā-ringa: ko te whakarerekētanga kaha ā-ringa te whakarerekētanga kaha tuatahi, ā, ko te mea tino whānuitia. Ko te kaupapa matua he whakarerekē i te ōwehenga o te mārama s me te mārama p i roto i te mārama pōrari mā te huri i te pereti haurua-ngaru, me te wehewehe i te mārama mā te pōrari. Mai i te whakarerekētanga ā-ringa tuatahi ki te tino aunoa me te tino tika o ēnei rā, kua tino pakari ngā momo hua me te whanaketanga tono.
2. Kaupapa hiko-whatu: ka taea e te kaiwhakatikatika kaha hiko-whatu te whakarerekē i te kaha, te whānui rānei o te mārama whakapōraru, ko te kaupapa matua e hangai ana ki te pānga Pockels o ngā tioata hiko-whatu. Ka huri te āhua pōraru o te hihi pōraru i muri i te whakamahinga o te tioata hiko-whatu me te mara hiko, kātahi ka wehea te pōraru e te pōraru. Ka taea te whakahaere i te kaha o te mārama e tukuna ana mā te whakarerekē i te kaha o te mara hiko, ā, ka taea te whakatutuki i te taha piki/heke o te rahi ns.
3. Kaupapa oro-whatu: ka taea hoki te whakamahi i te pūwhakatikatika oro-whatu hei pūwhakatikatika kaha. Mā te whakarerekē i te whai huatanga o te diffraction, ka taea te whakahaere i te mana o te 0 mārama me te 1 mārama kia tutuki ai te kaupapa o te whakarerekē i te kaha o te mārama. Ko te kuaha oro-whatu (whakaiti whatu) he āhuatanga o te tere whakarerekētanga tere me te paepae kino teitei.
4 Otinga tioata wai: he maha ngā wā ka whakamahia te taputapu tioata wai hei pereti ngaru taurangi, hei tātari rānei ka taea te whakarerekē, mā te whakamahi i te ngaohiko taraiwa i ngā pito e rua o te pouaka tioata wai hei tāpiri i tētahi huānga whakapūmau tika, ka taea te hanga hei kati tioata wai, hei whakaiti taurangi rānei, he nui te whakatuwheratanga o te hua nā roto i te mārama, me ngā āhuatanga pono teitei.
