Dab tsi technologies muaj rau cov ntsuas kub infrared
Vim li cas ho tsis tiv tauj infrared tus pas ntsuas kub?
Cov ntsuas kub tsis sib cuag infrared siv cov thev naus laus zis infrared los ntsuas qhov kub thiab txias ntawm cov khoom. Kev nyeem ntsuas kub tau nrawm nrawm yam tsis muaj kev sib cuag nrog cov khoom ntsuas. Tsuas yog tsom, nias lub cim thiab nyeem cov ntaub ntawv ntsuas kub ntawm LCD zaub. Cov ntsuas kub infrared yog lub teeb yuag, me me, siv tau yooj yim, thiab ntseeg tau tias ntsuas kub, txaus ntshai, lossis nyuaj rau cov khoom tsis muaj paug lossis ua rau cov khoom raug ntsuas. Cov ntsuas kub infrared tuaj yeem siv sijhawm ntau nyeem ib ob, thaum tiv tauj cov ntsuas kub siv sijhawm ob peb feeb ib feeb.
Qhov thib ob, tus pas ntsuas kub infrared yuav ua li cas?
Infrared tus pas ntsuas kub kom tau txais ntau yam khoom lawv tus kheej emit invisible infrared zog, infrared tawg yog ib feem ntawm cov electromagnetic spectrum, uas muaj xws li xov tooj cua tsis, microwaves, pom lub teeb, ultraviolet, R-rays thiab X-rays. Infrared nyob nruab nrab ntawm lub teeb pom kev thiab xov tooj cua tsis, infrared wavelengths feem ntau siv microns, lub wavelength ntau ntawm 0.7 microns - 1000 microns, qhov tseeb, 0.7 microns {{7 }} microns band siv rau infrared ntsuas kub.
Qhov thib peb, yuav ua li cas kom ntseeg tau tias qhov ntsuas kub ntawm infrared ntsuas qhov tseeb?
Infrared thev naus laus zis thiab nws cov hauv paus ntsiab lus ntawm kev nkag siab tsis txaus ntseeg ntawm nws qhov ntsuas kub zoo. Thaum ntsuas kub los ntawm infrared tus pas ntsuas kub, lub zog infrared tawm los ntawm cov khoom yuav tsum tau ntsuas, los ntawm qhov kho qhov muag ntawm lub ntsuas kub infrared hauv lub ntsuas ntsuas tau hloov mus rau lub teeb liab hluav taws xob, cov teeb liab ntsuas kub tau nthuav tawm, muaj ntau yam tseem ceeb uas. txiav txim siab qhov ntsuas kub, qhov tseem ceeb tshaj plaws yog qhov emissivity, qhov chaw pom, qhov deb ntawm qhov chaw thiab qhov chaw ntawm qhov chaw. Emissivity, tag nrho cov khoom muaj kev cuam tshuam, xa thiab emit zog, tsuas yog lub emission zog yog qhia txog qhov kub ntawm cov khoom. Thaum lub ntsuas kub infrared ntsuas qhov kub ntawm qhov chaw, qhov ntsuas tau txais tag nrho peb hom zog. Yog li ntawd, tag nrho cov ntsuas kub infrared yuav tsum tau kho kom nyeem tsuas yog lub zog tawm. Kev ntsuas qhov yuam kev feem ntau yog tshwm sim los ntawm lub zog infrared cuam tshuam los ntawm lwm qhov chaw teeb pom kev zoo. Qee qhov ntsuas kub infrared tuaj yeem sib txawv ntawm emissivity, thiab emissivity qhov tseem ceeb rau ntau yam ntaub ntawv tuaj yeem pom hauv cov ntawv luam tawm emissivity.
Lwm cov twj paj nruag muaj qhov ruaj khov emissivity pre-set rau 0.95. Tus nqi emissivity no yog qhov kub ntawm qhov chaw rau feem ntau cov ntaub ntawv organic, xim lossis oxidised nto, thiab yog them rau los ntawm kev siv daim kab xev los yog xim dub rau saum npoo hauv kev sim. Thaum daim kab xev los yog lacquer ncav cuag qhov kub ib yam li cov khoom siv substrate, qhov kub ntawm daim kab xev los yog lacquer nto yog ntsuas raws li nws qhov tseeb qhov kub thiab txias.
Distance rau Spot Ratio, qhov kho qhov muag ntawm lub ntsuas kub infrared sau lub zog los ntawm qhov chaw ntsuas qhov ncig thiab tsom nws ntawm lub ntsuas ntsuas. Kev daws teeb meem kho qhov muag txhais tau tias yog qhov piv ntawm qhov kev ncua deb ntawm lub ntsuas kub infrared mus rau qhov khoom mus rau qhov loj ntawm qhov chaw ntsuas (D:S). Qhov loj dua qhov sib piv, qhov zoo dua qhov kev daws teeb meem ntawm IR tus pas ntsuas kub thiab qhov me me ntawm qhov ntsuas qhov loj me. Laser aiming, tsuas yog siv los pab tsom ntawm qhov chaw ntsuas.
Qhov kev txhim kho tshiab tshaj plaws hauv infrared optics yog qhov sib ntxiv ntawm qhov ze-tsim feature, uas muab cov kev ntsuas tseeb ntawm cov phiaj xwm me me thiab tiv thaiv qhov cuam tshuam ntawm qhov kub thiab txias tom qab. Field of view, xyuas kom meej tias lub hom phiaj loj dua qhov chaw loj ntawm qhov ntsuas kub infrared ntsuas, qhov me dua lub hom phiaj, qhov ze nws yuav tsum yog. Thaum qhov tseeb yog qhov tseem ceeb tshwj xeeb, xyuas kom meej tias lub hom phiaj yog tsawg kawg ob zaug ntawm qhov chaw loj.
