Txoj cai ua haujlwm
Lub teeb ntuj yog tsim los ntawm lub teeb tsis muaj qhov sib txawv wavelengths.Qhov ntau pom ntawm tib neeg lub qhov muag yog 390-780nm.Lub electromagnetic nthwv dej luv dua 390nm thiab ntev dua 780nm tsis tuaj yeem hnov los ntawm tib neeg lub qhov muag.Ntawm lawv, electromagnetic tsis muaj wavelength tsawg dua 390nm yog sab nraum lub violet ntawm lub teeb pom kev zoo thiab hu ua ultraviolet rays;electromagnetic nthwv dej ntev dua 780nm sab nraum lub liab ntawm lub teeb pom kev zoo thiab hu ua infrared, thiab lawv cov wavelength ntawm 780nm mus rau 1mm.
Infrared yog electromagnetic nthwv dej nrog lub wavelength ntawm microwaves thiab pom lub teeb, thiab muaj tib lub ntsiab lus raws li xov tooj cua tsis thiab pom lub teeb.Nyob rau hauv qhov xwm txheej, txhua yam khoom uas nws qhov kub thiab txias yog siab tshaj li xoom (-273.15 ° C) tsis tu ncua radiate infrared rays.Qhov tshwm sim no hu ua thermal tawg.Infrared thermal imaging technology siv micro thermal radiation detector, optical imaging lub hom phiaj thiab opto-mechanical scanning system kom tau txais cov infrared hluav taws xob teeb liab ntawm cov khoom yuav tsum tau ntsuas, thiab tsom infrared hluav taws xob hluav taws xob faib qauv yog reflected mus rau lub photosensitive keeb ntawm lub infrared detector. Tom qab spectral filtering thiab spatial filtering, uas yog, lub infrared thermal duab ntawm cov khoom ntsuas tau soj ntsuam thiab tsom rau ntawm chav tsev los yog spectroscopic detector, lub infrared radiant zog hloov dua siab tshiab los ntawm lub detector rau hauv hluav taws xob teeb liab, uas yog amplified thiab hloov dua siab tshiab rau hauv standard video. teeb liab, thiab tso tawm kom pom raws li infrared thermal duab ntawm TV screen lossis saib.
Infrared yog ib tug electromagnetic yoj nrog tib lub ntsiab lus raws li xov tooj cua tsis thiab pom lub teeb.Qhov kev tshawb pom ntawm infrared yog kev dhia hauv tib neeg kev nkag siab txog xwm.Cov cuab yeej siv hluav taws xob tshwj xeeb los hloov qhov kub thiab txias ntawm qhov chaw ntawm ib qho khoom siv rau hauv cov duab pom rau tib neeg lub qhov muag thiab qhia txog qhov kub thiab txias ntawm qhov khoom ntawm cov xim sib txawv hu ua infrared thermal imaging technology.Cov khoom siv hluav taws xob no hu ua infrared thermal imager.
Infrared thermal imager siv infrared detector, optical imaging lub hom phiaj thiab opto-mechanical scanning system (tam sim no advanced focal dav hlau tshuab tshem tawm cov opto-mechanical scanning system) kom tau txais lub infrared hluav taws xob hluav taws xob faib qauv ntawm cov khoom yuav tsum tau ntsuas thiab muaj kev cuam tshuam rau nws. photosensitive element ntawm infrared ntes.Nyob nruab nrab ntawm lub tshuab kho qhov muag thiab lub ntsuas hluav taws xob infrared, muaj qhov kho qhov muag-mechanical scanning mechanism (lub focal dav hlau thermal imager tsis muaj lub tshuab no) txhawm rau luam theej duab infrared thermal duab ntawm cov khoom yuav tsum ntsuas thiab tsom nws ntawm chav tsev lossis spectroscopic detector. .Lub zog infrared radiant tau hloov mus rau hauv cov teeb liab hluav taws xob los ntawm lub tshuab ntes, thiab cov duab hluav taws xob infrared tso tawm rau ntawm lub vijtsam TV lossis saib tom qab kev nthuav dav thiab hloov mus rau cov teeb liab video.
Cov duab thermal zoo li no sib raug rau qhov chaw thermal faib rau ntawm qhov khoom;Hauv qhov tseem ceeb, nws yog daim duab thermal faib cov duab ntawm cov hluav taws xob infrared ntawm txhua feem ntawm cov khoom yuav ntsuas.Vim tias lub teeb liab tsis muaj zog heev, piv nrog cov duab pom lub teeb, nws tsis muaj qhov gradation thiab qhov thib peb.Txhawm rau txiav txim siab lub tshav kub infrared ntawm cov khoom kom ntsuas tau zoo dua hauv cov txheej txheem ua haujlwm tiag tiag, qee qhov kev pabcuam pabcuam feem ntau siv los ua kom cov haujlwm ua haujlwm ntawm lub ntsuas ntsuas, xws li kev tswj cov duab ci ntsa iab thiab qhov sib txawv, tus qauv tiag. kho, tsis tseeb xim kos duab contour thiab histogram rau kev ua lej, luam ntawv, thiab lwm yam.
Thermal imaging koob yees duab tau cog lus nyob rau hauv kev lag luam thaum muaj xwm ceev
Piv nrog rau cov koob yees duab pom lub teeb pom kev zoo uas tso siab rau lub teeb pom kev zoo lossis lub teeb pom kev zoo rau kev saib xyuas lub koob yees duab, lub koob yees duab thermal tsis tas yuav muaj lub teeb, thiab tuaj yeem pom meej cov duab tso siab rau lub tshav kub infrared los ntawm cov khoom nws tus kheej.Lub koob yees duab thermal imaging yog haum rau txhua qhov chaw teeb pom kev zoo thiab tsis cuam tshuam los ntawm lub teeb muaj zog.Nws tuaj yeem pom tseeb thiab pom cov hom phiaj, thiab txheeb xyuas cov hom phiaj zais thiab zais tsis hais hnub lossis hmo ntuj.Yog li, nws tuaj yeem paub txog kev saib xyuas 24-teev tiag tiag.
