Amalensi e-MWIR

Ilensi ye-infrared ephakathi kwamagagasies (Ilensi ye-MWIRes) ziyizingxenye ezibalulekile ezisetshenziswa ezinhlotsheni ezahlukene zokusebenza ezidinga izithombe zokushisa, njengokuqapha, ukutholwa kwethagethi, kanye nokuhlaziywa kokushisa. Lawa malensi asebenza esifundeni se-infrared esimaphakathi negagasi le-spectrum ye-electromagnetic, ngokuvamile phakathi kwama-micron angu-3 no-5 (Ilensi engu-3-5um), futhi zenzelwe ukugxila emisebeni ye-infrared ku-detector array.
Amalensi e-MWIR enziwe ngezinto ezingadlulisela futhi zigxile emisebeni ye-IR esifundeni se-MWIR. Izinto ezivame ukusetshenziswa kumalensi e-MWIR zifaka phakathi izibuko ze-germanium, i-silicon, kanye ne-chalcogenide. I-Germanium iyinto evame ukusetshenziswa kakhulu kumalensi e-MWIR ngenxa yenkomba yayo ephezulu yokugqama kanye nezici ezinhle zokudlulisela kububanzi be-MWIR.
Ilensi ye-MWIR iza ngemiklamo ehlukahlukene kanye nokucushwa, kuye ngokuthi isicelo sihloselwe ini. Enye yemiklamo evame kakhulu ilensi elula ye-plano-convex, enendawo eyodwa eyisicaba kanye nendawo eyodwa eyisicaba. Le lensi kulula ukuyikhiqiza futhi isetshenziswa ezinhlelweni eziningi lapho kudingeka khona uhlelo oluyisisekelo lokuthwebula izithombe. Eminye imiklamo ifaka phakathi amalensi amabili, aqukethe amalensi amabili anezinkomba ezahlukene zokubonisa ukukhanya, kanye namalensi okusondeza, angalungisa ubude be-focal ukuze asondeze noma akhiphe into.
Amalensi e-MWIR ayizingxenye ezibalulekile ezinhlelweni eziningi zokuthwebula izithombe ezisetshenziswa ezimbonini ezahlukahlukene. Empini, amalensi e-MWIR asetshenziswa ezinhlelweni zokuqapha, ezinhlelweni zokuqondisa ama-missile, kanye nezinhlelo zokuthola okuqondiwe. Ezindaweni zezimboni, amalensi e-MWIR asetshenziswa ekuhlaziyweni kokushisa kanye nezinhlelo zokulawula ikhwalithi. Ezinhlelweni zezokwelapha, amalensi e-MWIR asetshenziswa ekuthwebuleni izithombe ezishisayo ukuze kuhlolwe okungeyona ingozi.
Okunye okubalulekile okufanele kucatshangelwe lapho ukhetha ilensi ye-MWIR ubude bayo obuqondile. Ubude obuqondile belensi bunquma ibanga phakathi kwelensi kanye ne-detector array, kanye nosayizi wesithombe esikhiqizwayo. Isibonelo, ilensi enobude obufushane obuqondile izokhiqiza isithombe esikhulu, kodwa isithombe ngeke sibe nemininingwane eminingi. Ilensi enobude obuqondile obuqondile izokhiqiza isithombe esincane, kodwa isithombe sizoba nemininingwane eminingi, njengokuthiIlensi ye-MWIR engu-50mm.

Okunye okubalulekile okufanele kucatshangelwe ijubane laleli lensi, elinqunywa inombolo yalo ka-f. Inombolo ka-f iyisilinganiso sobude obuqondile nobubanzi belensi. Ilensi enenombolo ka-f ephansi izoshesha, okusho ukuthi ingabamba ukukhanya okwengeziwe ngesikhathi esifushane, futhi ivame ukuthandwa ezimweni zokukhanya okuphansi.
Ekuphetheni, amalensi e-MWIR ayisici esibalulekile ezinhlelweni eziningi zokuthwebula izithombe ezisetshenziswa ezimbonini ezahlukene. Aklanyelwe ukugxila emisebeni ye-infrared ku-detector array futhi eza ngemiklamo nezilungiselelo ezahlukahlukene, kuye ngokuthi kusetshenziswe ini.
