Kev soj ntsuam ntawm kev siv niaj hnub ntawm infrared thermometer technology
Lub hauv paus ntsiab lus ntsuas qhov ntsuas kub ntawm lub ntsuas kub infrared yog hloov lub zog hluav taws xob ntawm infrared rays emitted los ntawm ib yam khoom mus rau hauv lub teeb liab hluav taws xob. Qhov loj ntawm lub zog infrared radiant sib haum rau qhov kub ntawm qhov khoom nws tus kheej. Raws li qhov loj ntawm lub teeb liab hloov hluav taws xob, qhov kub ntawm qhov khoom tuaj yeem txiav txim siab. Kev ntsuas kub infrared thev naus laus zis tau tsim kho mus rau qhov chaw uas nws tuaj yeem luam theej duab thiab ntsuas qhov kub thiab txias ntawm qhov chaw nrog thermal hloov, txiav txim siab nws qhov kub thiab txias qhov sib txawv, thiab sai sai ntes qhov sib txawv ntawm qhov kub thiab txias. Qhov no yog lub koob yees duab infrared thermal imaging. Infrared thermal imaging koob yees duab tau xub siv nyob rau hauv cov tub rog. Lub Tuam Txhab Asmeskas TI tau tsim lub ntiaj teb thawj zaug infrared scanning reconnaissance system nyob rau hauv 1999. Txij thaum ntawd los, infrared thermal imaging technology tau siv nyob rau hauv dav hlau, tso tsheb hlau luam, warships thiab lwm yam riam phom nyob rau hauv Western lub teb chaws. , raws li thermal pom qhov system rau kev tshawb nrhiav lub hom phiaj, txhim kho kev muaj peev xwm tshawb nrhiav thiab ntaus lub hom phiaj. Lub koob yees duab infrared thermal imaging uas tsim los ntawm Swedish AGA lub tuam txhab yog nyob rau hauv ib txoj hauj lwm nyob rau hauv pej xeem technology.
Infrared tus pas ntsuas kub muaj cov khoom siv kho qhov muag, photoelectric detector, teeb liab amplifier, teeb liab ua, tso zis tso zis thiab lwm qhov chaw. Lub optical system sau lub hom phiaj infrared hluav taws xob hluav taws xob nyob rau hauv nws qhov kev pom. Qhov loj ntawm qhov kev pom yog txiav txim los ntawm qhov chaw kho qhov muag ntawm tus pas ntsuas kub thiab lawv txoj haujlwm. Lub zog infrared yog tsom rau lub photodetector thiab hloov mus rau hauv cov teeb liab hluav taws xob sib xws. Lub teeb liab dhau los ntawm lub amplifier thiab teeb liab ua Circuit Court, thiab hloov mus rau hauv tus nqi kub ntawm qhov ntsuas lub hom phiaj tom qab kho raws li kev kho sab hauv algorithm ntawm qhov ntsuas thiab lub hom phiaj emissivity.
Nyob rau hauv qhov xwm txheej, tag nrho cov khoom uas muaj qhov kub siab tshaj li xoom yog tas li emitting infrared hluav taws xob hluav taws xob mus rau qhov chaw nyob ib puag ncig. Tus nqi ntawm infrared hluav taws xob hluav taws xob ntawm ib yam khoom thiab nws qhov kev faib tawm raws li wavelength yog ze ze rau nws qhov kub thiab txias. Yog li, los ntawm kev ntsuas lub zog infrared radiated los ntawm cov khoom nws tus kheej, nws qhov kub thiab txias tuaj yeem ntsuas qhov tseeb. Qhov no yog lub hom phiaj ntawm lub hauv paus ntawm qhov ntsuas kub ntawm infrared radiation.
Lub cev dub yog lub tshuab hluav taws xob zoo tshaj plaws uas nqus lub zog ntawm txhua lub wavelengths yam tsis muaj lub zog xav txog lossis kev sib kis. Nws qhov emissivity saum npoo yog 1. Txawm li cas los xij, yuav luag txhua yam khoom muaj nyob hauv qhov tsis yog lub cev dub. Txhawm rau kom paub meej thiab tau txais cov cai faib tawm ntawm cov hluav taws xob infrared, yuav tsum xaiv cov qauv tsim nyog hauv kev tshawb fawb theoretical. Qhov no yog quantized oscillator qauv ntawm lub cev kab noj hniav hluav taws xob npaj los ntawm Planck. Planck txoj cai ntawm lub cev dub hluav taws xob tau muab los, uas yog, lub cev dub spectral radiance qhia nyob rau hauv wavelength. Qhov no yog qhov pib ntawm tag nrho infrared radiation theories, yog li nws yog hu ua txoj cai dub lub cev hluav taws xob. Tus nqi hluav taws xob ntawm tag nrho cov khoom tiag tiag tsis yog nyob ntawm qhov hluav taws xob wavelength thiab qhov kub thiab txias ntawm cov khoom, tab sis kuj yog nyob ntawm cov khoom xws li hom khoom, kev npaj, txheej txheem thermal, lub xeev saum npoo thiab ib puag ncig ntawm cov khoom.
Kev ntsuas kub infrared txais kev ntsuas point-by-point, uas yog, thermal tawg ntawm ib cheeb tsam hauv cheeb tsam ntawm cov khoom yog tsom rau ntawm ib qho kev ntsuas, thiab lub zog hluav taws xob tau hloov mus rau hauv qhov kub thiab txias los ntawm emissivity ntawm cov khoom paub. Vim tias cov khoom sib txawv yuav raug kuaj pom, ntsuas qhov ntau thiab siv sijhawm, cov qauv tsim thiab cov qauv sab hauv ntawm cov ntsuas kub infrared sib txawv, tab sis cov qauv yooj yim feem ntau zoo sib xws, suav nrog cov tshuab kho qhov muag, photodetectors, teeb liab amplifiers thiab cov teeb liab ua, thiab cov khoom tso tawm. tsim los ntawm lwm qhov chaw. Infrared hluav taws xob emitted los ntawm lub radiator. Nkag mus rau qhov kho qhov muag, cov hluav taws xob infrared yog hloov pauv mus rau hauv cov hluav taws xob hloov pauv los ntawm lub modulator, thiab tom qab ntawd hloov mus rau cov khoom siv hluav taws xob sib txuas los ntawm lub tshuab ntes. Lub teeb liab dhau los ntawm lub amplifier thiab teeb liab ua Circuit Court, thiab hloov mus rau hauv tus nqi kub ntawm qhov ntsuas lub hom phiaj tom qab kho raws li algorithm hauv qhov ntsuas thiab lub hom phiaj emissivity.
