Lub hauv paus ntsiab lus ntawm thermal imaging night vision instrument:
Thermal imaging yog passive infrared, uas yog generated los ntawm tau txais qhov kub thiab txias (thermal zog) ntawm ib yam khoom thiab ua nws rau hauv ib tug duab rau zaub. Feem ntau, cov duab yog greyish dawb tsis hais hnub los yog hmo ntuj.
Thermal duab tsis yog active infrared. Lub thermal imaging hmo ntuj pom kev ntaus ntawv nws tus kheej tsis emit infrared rays, tab sis tsuas yog tau txais ib tug ntau yam ntawm infrared rays. Yog li ntawd, nws yog ib qho yooj yim los txiav txim siab tias ntev npaum li qhov thermal imaging tuaj yeem tau txais cov kab hluav taws xob infrared tawm los ntawm cov khoom, muaj cov duab tso tawm. Hloov pauv, yog tias cov hluav taws xob infrared tsis tuaj yeem txais, nws tsis tuaj yeem cuam tshuam cov duab ntawm cov khoom peb xav pom.
Yog li tam sim no qee cov lus nug uas peb txhua tus tau nug, xws li seb cov duab thermal puas tuaj yeem pom, nkag mus rau phab ntsa, pom tib neeg thiab cov khoom hauv tsheb, thiab nkag mus rau iav, muaj qee qhov txiaj ntsig.
Yog tias koj hla cov phab ntsa lossis iav, phab ntsa thaiv cov kab hluav taws xob infrared, thiab cov thermal imaging hmo ntuj pom kev tsis tuaj yeem txais cov kab hluav taws xob infrared thiab tsis tuaj yeem ntes cov khoom ntawm sab nraud ntawm phab ntsa thiab iav. Qhov ntawd yog hais tias, yog tias muaj cov duab, nws yuav tsum tsis txhob thaiv tag nrho cov khoom kaw, txwv tsis pub cov duab infrared yuav tsis tau txais.
Nyob rau hauv ib puag ncig xws li ntoo thiab nyom, thermal imaging tseem tuaj yeem ntes cov khoom uas kub dua li cov nroj tsuag vim tsis thaiv lub teeb infrared kiag li. Yog tias muaj tib neeg thiab tsiaj txhu tom qab cov nyom thiab ntoo, nws pom tseeb tias muaj qhov kub thiab txias sib txawv. Cov khoom uas muaj qhov kub thiab txias yuav teeb, thaum cov khoom uas muaj qhov kub thiab txias yuav tsaus dua.
Thermal imaging yog qhov sib txawv ntawm qhov kub thiab txias. Cov khoom uas muaj qhov kub thiab txias tshaj tawm cov hluav taws xob muaj zog infrared, thaum cov khoom uas muaj qhov kub tsis tshua muaj hluav taws xob tsis muaj zog infrared.
Thaum ib tug neeg taug kev tom qab lub iav, lawv tsis tuaj yeem pom cov duab ntawm tus neeg vim lub iav thaiv cov kab hluav taws xob infrared ntawm tus neeg sab nraud, thiab cov khoom siv thermal imaging hmo ntuj tsis tuaj yeem tau txais cov kab hluav taws xob infrared, yog li nws tsis tuaj yeem pom qhov pom ntawm tus neeg. hauv daim duab.
Ob tug neeg sawv sab hauv, nrog ib tug neeg nyob rau hauv daim duab thiab ib tug neeg nyob rau saum lub iav. Qhov no yog vim qhov infrared ntawm tus neeg tau txais los ntawm tib neeg thermal imaging. Tsis tas li ntawd, muaj cov neeg nyob rau ntawm lub khob vim tib neeg infrared yog emissions nyob rau hauv tag nrho cov kev taw qhia, thiab infrared emissions mus rau lub iav yog reflected rov qab los ntawm lub iav thiab tau txais los ntawm lub thermal imaging hmo ntuj pom kev ntaus ntawv. Yog li ntawd, peb tuaj yeem pom cov duab ntawm tus neeg ntawm lub khob.
Thaum ib tug neeg hnav khaub ncaws, feem ntau ntawm cov kab hluav taws xob infrared raug thaiv los ntawm cov khaub ncaws, thiab lub cev ntawm lub cev yog xim dub vim tias qhov kub ntawm cov khaub ncaws qis dua li ntawm tus neeg lub taub hau. Lub taub hau nrog kub kub yog ci dua, thaum cov khaub ncaws uas tsis tshua muaj kub yog tsaus dua.
Lub sijhawm no, ib tug neeg muab ob txhais tes tso rau ntawm cov khaub ncaws rau 2 vib nas this, thiab peb pom tias muaj ob lub xib teg ntawm cov khaub ncaws. Ntawd yog, qhov ntsuas kub ntawm xibtes tau xa mus rau cov khaub ncaws, thiab qhov kub ntawm xibtes ploj tom qab 2 lossis 3 vib nas this. Ntawd yog, qhov kub ntawm xibtes ntawm cov khaub ncaws maj mam dissipated thiab ploj mus.
