Dab tsi yog qhov txawv ntawm ntau hom khoom siv thaum hmo ntuj?
Cov cuab yeej pom kev hmo ntuj tau muab faib ua thawj, thib ob thiab thib peb tiam raws li qib ntawm cov raj intensifier.
Lub cim thib peb yog qhov kev siv tshuab pom kev hmo ntuj tshaj plaws hauv cov neeg pej xeem tam sim no. Nws nto yog coated nrog ib tug heev rhiab heev gallium arsenide photocathode txheej, uas muaj peev xwm hloov lub teeb mus rau hauv hluav taws xob zoo nyob rau hauv lub teeb tsis muaj zog heev. Lub cim thib peb muab cov duab meej, pom kev hmo ntuj. Muaj kev ua haujlwm siab cov duab intensifier raj nrog qhov tsawg kawg nkaus ntawm 51lp / mm, uas yog 3 units saum toj kawg nkaus tus qauv ntawm 45lp / mm. Kab ib millimeter (lp/mm) yog chav ntsuas uas siab dua cov duab intensifiers tsim cov duab sharper.
Cov phaj nkag tau tsim los ntawm tiam thib ob tuaj yeem tsim tau kaum tawm txhiab tus electrons. Qhov no ua rau cov duab pom tseeb hauv cov xwm txheej hmo ntuj, tsis muaj kev cuam tshuam piv rau Generation 1 thiab Generation Zero.
Thawj tiam muaj teeb meem nrog distortion thiab lub neej luv luv ntawm cov hlab ntsha. Nws siv cov ntaub ntawv uas hloov photoelectrons tau zoo dua li Generation Zero. Cov khoom siv no muaj peev xwm ua haujlwm ntawm lub teeb qis dua li Generation Zero, hu ua "starlight". Imported night vision goggles feem ntau siv thawj tiam duab intensifiers, txawm tias lawv tau tshaj tawm tias yog tiam thib ob.
Hauv Generation Zero, nws tso siab rau lub teeb lub zog los txhim kho lub teeb sab nraud. Lub teeb-hloov hluav taws xob yog tsom los ntawm cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob no tau nrawm los ntawm cov khoom siv conical (anode), yog li lawv muaj zog ntau dua thaum lawv ntaus lub vijtsam fluorescent, yog li tsim cov duab. Hmoov tsis zoo, kev ua kom cov hluav taws xob ua kom zoo li no ua rau txo cov duab zoo thiab luv luv lifespan rau lub kinescope.
Tag nrho cov khoom muag mus rau thoob ntiaj teb kev lag luam ntawm peb tiam yuav tsum tau txais daim ntawv tso cai export los ntawm US State Department, uas yog ib tug tiv thaiv kev lag luam tswj cov khoom, raws li lub US Federal International Transportation of Arms (ITAR), Tshooj 22. Feem ntau ntawm Ob yam khoom yog tswj hwm los ntawm US Department of Commerce rau export, catalog tooj 6A002.
