Daim ntawv thov kev tshuaj ntsuam ntawm Modern Infrared Thermometers
Lub hauv paus ntsiab lus ntsuas kub ntawm lub ntsuas kub infrared yog hloov lub zog infrared radiant tawm los ntawm cov khoom mus rau hauv lub teeb liab hluav taws xob. Qhov loj ntawm lub zog hluav taws xob infrared sib raug 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. Infrared ntsuas kub ntsuas tshuab tau tsim los ntsuas thiab ntsuas qhov kub ntawm qhov chaw nrog thermal hloov, txiav txim siab nws qhov kub thiab txias faib cov duab, thiab ceev nrooj pom qhov sib txawv ntawm qhov kub thiab txias. Qhov no yog lub infrared thermal imager. Infrared thermal imaging koob yees duab tau xub siv nyob rau hauv cov tub rog. Hauv xyoo 2019, TI Corporation ntawm Tebchaws Meskas tau tsim lub ntiaj teb thawj zaug infrared scanning reconnaissance system. Tom qab ntawd, infrared thermal imaging thev naus laus zis tau ua tiav hauv dav hlau, tso tsheb hlau luam, nkoj nkoj thiab lwm yam riam phom hauv Western lub teb chaws, raws li lub thermal pom qhov system rau kev soj ntsuam lub hom phiaj, nws zoo heev txhim kho lub peev xwm tshawb nrhiav thiab ntaus lub hom phiaj. Lub koob yees duab infrared thermal imaging uas tsim los ntawm Swedish AGA tuam txhab yog nyob rau hauv ib txoj hauj lwm nyob rau hauv pej xeem technology.
Tus pas ntsuas kub infrared yog tsim los ntawm optical system, photoelectric detector, teeb liab amplifier, teeb liab ua, tso zis tso zis thiab lwm yam. Lub tshuab kho qhov muag sib sau ua ke lub hom phiaj infrared hluav taws xob hluav taws xob hauv nws qhov chaw saib, thiab qhov loj ntawm qhov kev pom yog txiav txim los ntawm qhov chaw kho qhov muag ntawm tus pas ntsuas kub thiab nws txoj hauj lwm. 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 raug kho raws li algorithm ntawm kev kho sab hauv ntawm lub ntsuas thiab emissivity ntawm lub hom phiaj.
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. Qhov loj ntawm lub zog hluav taws xob infrared ntawm ib yam khoom thiab nws qhov kev faib tawm los ntawm 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 txiav txim siab, uas yog lub hauv paus rau kev ntsuas kub ntawm infrared radiation.
Lub cev dub yog lub tshuab hluav taws xob zoo tshaj plaws, uas nqus tau tag nrho cov wavelengths ntawm lub zog hluav taws xob, tsis muaj kev xav lossis kev xa tawm ntawm lub zog, thiab muaj 1 emissivity ntawm nws qhov chaw. Txawm li cas los xij, cov khoom siv hauv qhov xwm txheej yuav luag tsis yog lub cev dub. Txhawm rau kom paub meej thiab tau txais kev faib tawm ntawm cov hluav taws xob infrared, ib qho qauv tsim nyog yuav tsum raug xaiv hauv kev tshawb fawb theoretical. Qhov no yog qhov quantized oscillator qauv ntawm lub cev kab noj hniav hluav taws xob tau npaj los ntawm Planck, yog li muab tau txoj cai ntawm Planck lub cev dub hluav taws xob, uas yog, lub cev dub spectral radiance qhia los ntawm wavelength, uas yog qhov pib ntawm tag nrho cov infrared radiation theories, yog li nws yog. hu ua txoj cai ntawm lub cev dub tawg. Tus nqi hluav taws xob ntawm tag nrho cov khoom tiag tiag nyob ntawm tsis yog tsuas yog nyob ntawm qhov hluav taws xob wavelength thiab qhov kub ntawm cov khoom, tab sis kuj yog nyob ntawm hom khoom tsim los ntawm cov khoom, cov txheej txheem kev npaj, txheej txheem thermal, lub xeev saum npoo thiab ib puag ncig.
Kev ntsuas kub infrared txais ib txoj kev tsom xam 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 cov hluav taws xob hluav taws xob tau hloov mus rau hauv qhov kub thiab txias los ntawm emissivity ntawm cov khoom paub. . Vim yog cov khoom sib txawv, kev ntsuas ntau thiab siv sijhawm, cov qauv tsim thiab sab hauv ntawm cov ntsuas kub infrared sib txawv, tab sis cov qauv yooj yim feem ntau zoo sib xws, feem ntau suav nrog optical system, photodetector, teeb liab amplifier thiab teeb liab ua, tso zis tawm thiab lwm yam. ntu. 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 hloov mus rau hauv cov teeb liab hluav taws xob sib xws los ntawm lub tshuab ntes. Lub teeb liab dhau los ntawm lub amplifier thiab teeb liab ua Circuit Court, thiab hloov mus rau qhov kub ntawm qhov ntsuas lub hom phiaj tom qab raug kho raws li algorithm hauv qhov ntsuas thiab lub hom phiaj emissivity.
