Indorerwamo za MWIR

Ikirahuri cy'infrarouge kiri hagati mu mashanyarazies (Ikirahuri cya MWIRes) ni ibice by'ingenzi bikoreshwa mu buryo butandukanye busaba amashusho y'ubushyuhe, nko kugenzura, kubona intego, no gusesengura ubushyuhe. Izi lenzi zikorera mu gace k'imirasire y'amashanyarazi yo hagati mu gice cy'urumuri rw'amashanyarazi, ubusanzwe hagati ya mikoroni 3 na 5 (Ikirahuri cya 3-5um), kandi byagenewe gushyira imirasire ya infrared ku gice cy’icyuma gipima.
Indorerwamo za MWIR zikozwe mu bikoresho bishobora kohereza no gushyira imirasire ya IR mu gace ka MWIR. Ibikoresho bikunze gukoreshwa ku ndorerwamo za MWIR birimo indorerwamo za germanium, silicon, na chalcogenide. Germanium ni yo ikoreshwa cyane ku ndorerwamo za MWIR bitewe n'uko ifite ubushobozi bwo kurekura urumuri cyane ndetse n'imiterere myiza yo kohereza urumuri mu bwoko bwa MWIR.
Ilensi ya MWIR iza mu buryo butandukanye kandi ikagira imiterere itandukanye, bitewe n'uburyo ikoreshwa. Imwe mu miterere ikunze kugaragara ni lensi yoroshye ya plano-convex, ifite ubuso bumwe burambuye n'ubuso bumwe burambuye. Iyi lensi yoroshye kuyikora kandi ikoreshwa mu bikorwa byinshi aho hakenewe sisitemu y'ibanze yo gufata amashusho. Izindi miterere irimo lensi ebyiri, zigizwe n'ingero ebyiri zifite indices zitandukanye zo kurekura, na lensi zoom, zishobora guhindura uburebure bw'ifatizo kugira ngo zoom yinjire cyangwa isohoke ku kintu.
Indorerwamo za MWIR ni ingenzi mu buryo bwinshi bwo gufata amashusho bukoreshwa mu nganda zitandukanye. Mu gisirikare, indorerwamo za MWIR zikoreshwa mu buryo bwo kugenzura, mu buryo bwo kuyobora ibisasu bya misile, no mu buryo bwo kubona intego. Mu nganda, indorerwamo za MWIR zikoreshwa mu gusesengura ubushyuhe no mu buryo bwo kugenzura ubuziranenge. Mu buvuzi, indorerwamo za MWIR zikoreshwa mu gupima ubushyuhe mu gusuzuma indwara zidakunze kugaragara.
Kimwe mu bintu by'ingenzi ugomba kwitaho mu guhitamo lenzi ya MWIR ni uburebure bwayo bw'ibanze. Uburebure bw'ibanze bwa lenzi bugena intera iri hagati ya lenzi n'urutonde rw'ibikoresho bipima urumuri, ndetse n'ingano y'ishusho ikorwa. Urugero, lenzi ifite uburebure bugufi bw'ibanze izatanga ishusho nini, ariko ishusho izaba idakubiyemo ibisobanuro birambuye. Lenzi ifite uburebure bunini bw'ibanze izatanga ishusho nto, ariko ishusho izaba ifite ibisobanuro birambuye, urugero nkaIkirahuri cya MWIR cya 50mm.

Ikindi kintu cy'ingenzi kigomba kwitabwaho ni umuvuduko wa lens, ugenwa n'umubare wayo wa f. Umubare wa f ni igipimo cy'uburebure bw'ibanze n'umurambararo wa lens. Lens ifite umubare wa f uri hasi izaba yihuta, bivuze ko ishobora gufata urumuri rwinshi mu gihe gito, kandi akenshi ikundwa mu bihe by'urumuri ruto.
Muri make, lenzi za MWIR ni ingenzi cyane muri sisitemu nyinshi zo gufata amashusho zikoreshwa mu nganda zitandukanye. Zagenewe gushyira imirasire ya infrared ku gice cy’icyuma gipima amashusho kandi ziza mu buryo butandukanye n’imiterere itandukanye, bitewe n’uburyo zikoreshwa.
