I te mea kei te whānui haere tonu ngā tono taiaho mana-teitei, kua noho ko ngā pae taiaho he mea nui ki ngā wāhi pēnei i te papu taiaho, te tukatuka ahumahi, ngā taputapu hauora, me te rangahau pūtaiao. Nā te kaha o te mana, te tauine ā-whakarerekētanga, me te pai o te hiko-whatu, ko ēnei taputapu te kaupapa matua o te maha o ngā pūnaha taiaho hou. Heoi, i roto i ngā tohu mahi maha o te pae taiaho taiaho, kotahi te tawhā e warewarehia ana engari he mea tino nui: ko te koki wehewehe. Ka tūhuratia e tēnei tuhinga ngā āhuatanga, ngā takenga ā-tinana, me ngā pānga o te koki wehewehe i roto i ngā pae taiaho taiaho—me pēhea te whakahaere pai a te hoahoa whatu.
1. He aha te Koki Whakarerekētanga?
Ko te koki wehewehe e whakaahua ana i te horapa o te hihi laser i a ia e horapa ana i te wāhi wātea. E tohu ana i te whānuitanga o te horapa o te hihi mai i te taha tuku. I roto i ngā pae diode laser, ka whakaatuhia e te koki wehewehe te kore taurite i ngā ahunga matua e rua:
Tuaka Tere: Tū poutū ki te mata o te pae. He tino whaiti te rohe tukunga (1–2 µm te nuinga), ā, he nui ngā koki wehewehe, he maha ngā wā 30°–45°, neke atu rānei.
Tuaka Pōturi: E whakarara ana ki te roa o te pae. He whānui ake te rohe tukunga (rau maikorona), ka iti ake ngā koki wehewehe, i te nuinga o te wā i te 5°–15°.
He wero nui tēnei rerekētanga kore taurite mō te hoahoa mō te whakaurunga pūnaha e whakamahi ana i ngā pae diode taiaho.
2. Te Pūtake ā-Tinana o te Rerekētanga
Ko te koki wehewehenga ka whakatauhia tuatahitia e te hanganga arataki ngaru me te rahi o te taha tuku:
I te tuaka tere, he tino iti te horahanga tukunga. E ai ki te ariā diffraction, ka nui ake te divergence i ngā kōhao iti.
I te tuaka puhoi, ka whānui te hihi i te roanga o te pae puta noa i ngā kaituku maha, ka iti ake te koki wehewehenga.
Nā reira, he nui te rerekētanga o ngā pae diode taiaho i te tuaka tere, he iti hoki te rerekētanga i te tuaka puhoi.
3. Te Pānga o te Koki Whakarerekētanga ki te Hoahoa Pūnaha
① Te Utu Nui o te Whakakotahitanga me te Hanga Kurupae
Nā te kore taurite o te hihi mata, me whakamahi ngā karu FAC (Fast Axis Collimation) me te SAC (Slow Axis Collimation). Ka whakanui ake tēnei i te uaua o te pūnaha, ā, me nui te tika o te tāutanga me te pumau o te wera.
② Te Whai Huatanga o te Hononga Muka Iti
Ina honoa ngā pae taiaho ki ngā muka aratau maha, ki ngā pūnaha whatu, ki ngā karāhe aspheric rānei, ka taea e te rerekētanga nui o te tuaka tere te arahi ki te "whiwhinga hihi," ka whakaiti i te pai o te hononga. Ko te rerekētanga tetahi o ngā pūtake nui o te ngaronga whatu.
③ Te Kounga o te Hiko i roto i te Whakatakotoranga o te Module
I roto i ngā kōwae whakarārangi maha-pae, ka taea e te rerekētanga kāore i te whakahaeretia te whakaputa i te taupatupatu hihi kāore i te ōrite, te he rānei o te papa-tawhiti, ka pā ki te tika o te arotahi me te tohatoha wera.
4. Me pēhea te Whakahaere me te Arotau i te Wehewehenga i roto i ngā Pae Diode Taiaho
Ahakoa te nuinga o te wā e tautuhia ana te rerekētanga e te hanganga o te taputapu, he maha ngā rautaki taumata-pūnaha ka taea te whakamahi hei arotau:
①Te Whakamahinga o ngā Arotahi FAC
Mā te whakanoho i tētahi karu arotahi collimation tuaka-tere tata ki te taha whakaputa ka kōpeke te hihi, ka whakaiti hoki i te rerekētanga i roto i te tuaka-tere—he mea nui tēnei mō te nuinga o ngā hoahoa.
②Ngā Arotahi SAC mō te Hanga Tāpiri
Ahakoa he iti ake te rerekētanga puhoi o te tuaka, me whai āhua tonu i roto i ngā rarangi, i ngā pūtake rama-rārangi rānei kia ōrite ai te putanga.
③Te Whakakotahitanga Hiko me te Hoahoa Hanga Whatu
Mā te whakamahi i ngā huinga arotahi-iti, ngā arotahi porotaka, ngā tirohanga whatu hanganga rānei, ka taea te hanga i ngā hihi laser maha kia puta he putanga kanapa teitei, ōrite hoki.
④Arotautanga Aratohu Ngaru Taumata-Pūrere
Mā te whakarerekē i te matotoru o te paparanga hohe, te hoahoa arataki ngaru, me ngā hanganga kupenga ka taea te whakapai ake i te rerekētanga tuaka-tere mai i te taumata maramara.
5. Te Whakahaere i te Rerekētanga i roto i ngā Taupānga o te Ao Tūturu
①Ngā Pūtake Papu Taiaho
I roto i ngā pūnaha taiaho totoka-āhua-teitei, i ngā pūnaha taiaho muka rānei, ka mahi ngā pae taiaho hei pūtake papu. Mā te whakahaere i te rerekētanga—ina koa i te tuaka tere—ka whakapai ake i te pai o te hononga me te arotahi hihi.
②Ngā Pūrere Hauora
Mō ngā pūnaha pēnei i te whakaora taiaho me te tango huruhuru, mā te whakahaere i te rerekētanga ka nui ake te tuku pūngao me te maimoatanga haumaru ake, whai hua ake hoki.
③Te Tukatuka Rauemi Ahumahi
I roto i te whakarewa me te tapahi taiaho, ka whai wāhi te rerekētanga kua arotauhia ki te whakanui ake i te mātotoru mana, te arotahi pai ake, me te tukatuka tika ake, whai hua ake.
6. Whakamutunga
Ko te koki wehewehe o te pae diode taiaho he pūwāhi whakawhiti nui—mai i te ahupūngao maramara tauine-morahi ki ngā pūnaha whatu tauine-nui.
He tohu kounga hihi, he rohe hoahoa hoki mō te whakaurunga. I te piki haere tonu o ngā tono tono me te uauatanga o te pūnaha, ko te mārama me te whakahaere i te rerekētanga ka noho hei pūkenga matua mā ngā kaihanga me ngā kaiwhakauru taiaho—ina koa mō te ahu whakamua ki te kaha teitei ake, te kanapa, me te pono.
