Dab tsi yog cov khoom ntawm lub ntsuas kub infrared?
Txhua yam khoom uas kub siab tshaj xoom (-273.15 degree) yog tsis tu ncua emitting infrared zog mus rau qhov chaw nyob ib puag ncig. Nws cov yam ntxwv hluav taws xob, qhov loj ntawm hluav taws xob hluav taws xob, kev faib tawm wavelength, thiab lwm yam yog ze rau qhov kub ntawm qhov khoom. Hloov pauv, los ntawm kev ntsuas lub zog infrared tawm los ntawm ib qho khoom nws tus kheej, nws qhov kub thiab txias tuaj yeem ntsuas qhov tseeb, uas yog lub tshuab ntsuas hluav taws xob hluav taws xob ntsuas kub.
Tib neeg lub cev, zoo li lwm yam kab mob, kuj radiates thiab tso tawm infrared zog rau ib puag ncig, nrog wavelengths feem ntau ntawm {{0}} μ m. Nws nyob nruab nrab ntawm 0.76 thiab 100 μ Qhov ze-infrared band ntawm m. Vim lub fact tias lub teeb nyob rau hauv no wavelength ntau yog tsis absorbed los ntawm huab cua, uas yog hais tias, tus nqi ntawm infrared hluav taws xob emissions los ntawm tib neeg lub cev tsis muaj feem xyuam rau ib puag ncig, tab sis tsuas yog rau tus nqi ntawm lub zog khaws cia thiab tso tawm. tib neeg lub cev. Yog li ntawd, ntev npaum li lub zog infrared tawm los ntawm tib neeg lub cev raug ntsuas, qhov kub thiab txias ntawm tib neeg lub cev tuaj yeem ntsuas qhov tseeb. Lub ntsuas kub infrared ntawm tib neeg lub cev yog tsim thiab tsim raws li txoj cai no.
Cov txheej txheem ua haujlwm ntawm tus pas ntsuas kub infrared: Cov ntsuas kub infrared yog tsim los ntawm cov khoom siv kho qhov muag, lub photodetector, lub teeb liab amplifier, teeb liab ua, tso zis tawm, thiab lwm yam khoom. Lub tshuab kho qhov muag sib sau ua ke lub zog hluav taws xob infrared ntawm lub hom phiaj hauv nws qhov kev pom, thiab qhov loj ntawm qhov kev pom yog txiav txim siab los ntawm cov khoom siv kho qhov muag thiab txoj hauj lwm ntawm tus pas ntsuas kub. Cov hluav taws xob infrared los ntawm cov khoom ntsuas ua ntej nkag mus rau hauv qhov muag pom ntawm tus pas ntsuas kub, thiab tom qab ntawd cov hluav taws xob infrared yog concentrated los ntawm cov khoom siv kho qhov muag, ua rau lub zog ntau dua; Cov infrared sib sau ua ke yog nkag mus rau hauv lub photodetector, thiab cov khoom tseem ceeb ntawm lub detector yog infrared sensor, uas nws txoj hauj lwm yog los hloov cov teeb liab kho qhov muag rau hauv lub teeb liab hluav taws xob; Lub teeb liab hluav taws xob tso zis los ntawm photodetector yog hloov mus rau qhov kub ntawm qhov ntsuas lub hom phiaj tom qab tau ntsuas los ntawm lub suab nrov thiab teeb liab ua haujlwm raws li lub hauv paus algorithm thiab lub hom phiaj emissivity ntawm lub ntsuas.
