Ngā Arotahi MWIR

Karāhe pūwhero waenga-ngarungā (Arotahi MWIRes) he wāhanga nui e whakamahia ana i roto i ngā momo tono e hiahia ana ki te whakaahua wera, pērā i te tirotiro, te hopu ūnga, me te tātari wera. Ka mahi ēnei karu arotahi i te rohe infrared waenga-ngaru o te whānuitanga hikohiko, i waenga i te 3 me te 5 microns (Karāhe arotahi 3-5um), ā, kua hangaia hei arotahi i te irahiko pūwero ki runga i tētahi huinga pūoko.
He mea hanga ngā karāhe MWIR mai i ngā rauemi ka taea te tuku me te arotahi i te hihi IR ki roto i te rohe MWIR. Ko ngā rauemi e whakamahia whānuitia ana mō ngā karāhe MWIR ko te germanium, te silicon, me ngā karāhe chalcogenide. Ko te germanium te rauemi e whakamahia whānuitia ana mō ngā karāhe MWIR nā tōna taupū whakaata teitei me ōna āhuatanga tuku pai i roto i te awhe MWIR.
He maha ngā hoahoa me ngā whirihoranga o te karāhe MWIR, i runga i te whakamahinga e hiahiatia ana. Ko tētahi o ngā hoahoa tino noa ko te karāhe plano-convex māmā, he mata papatahi kotahi, he mata kōpuku kotahi. He ngāwari te hanga i tēnei karāhe, ā, e whakamahia ana i roto i ngā whakamahinga maha e hiahiatia ana he pūnaha whakaahua taketake. Ko ētahi atu hoahoa ko ngā karāhe takirua, e rua ngā karāhe me ngā taupū whakaata rerekē, me ngā karāhe whakanui, ka taea te whakarite i te roa arotahi hei whakanui ake, hei whakanui ake rānei i tētahi mea.
He wāhanga nui ngā karāhe MWIR i roto i ngā pūnaha whakaahua maha e whakamahia ana i roto i ngā ahumahi maha. I roto i te ope taua, ka whakamahia ngā karāhe MWIR i roto i ngā pūnaha tirotiro, ngā pūnaha ārahi pere, me ngā pūnaha hopu ūnga. I roto i ngā tautuhinga ahumahi, ka whakamahia ngā karāhe MWIR i roto i ngā pūnaha tātaritanga wera me te whakahaere kounga. I roto i ngā tono hauora, ka whakamahia ngā karāhe MWIR i roto i te whakaahua wera mō ngā tātaritanga kore-whakaeke.
Ko tētahi whakaaro nui i te wā e whiriwhiri ana i tētahi arotahi MWIR ko tōna roa arotahi. Ko te roa arotahi o tētahi arotahi te mea e whakatau ana i te tawhiti i waenga i te arotahi me te huinga pūoko, tae atu ki te rahi o te ahua ka puta. Hei tauira, ka nui ake te ahua o tētahi arotahi poto ake, engari ka iti ake te taipitopito o te ahua. Ka iti ake te ahua o tētahi arotahi roa ake, engari ka nui ake te taipitopito o te ahua, pērā iArotahi MWIR 50mm.

Ko tētahi atu whakaaro nui ko te tere o te arotahi, e whakatauhia ana e tōna tau-f. Ko te tau-f te ōwehenga o te roa arotahi ki te whānui o te arotahi. Ka tere ake te arotahi he tau-f iti ake, arā, ka taea e ia te hopu i te nui ake o te mārama i roto i te wā poto ake, ā, he pai ake i ngā āhuatanga mārama iti.
Hei whakamutunga, he wāhanga nui ngā karāhe MWIR i roto i ngā pūnaha whakaahua maha e whakamahia ana i roto i ngā momo ahumahi. He mea hanga ēnei hei arotahi i te irahiko pūwero ki runga i tētahi huinga taputapu tirotiro, ā, he maha ngā hoahoa me ngā whirihoranga e wātea ana, i runga i te tono e hiahiatia ana.
