Txhua yam khoom nrog ib qho kub tshaj saud xoom radiates zog rau hauv qhov chaw sab nraud hauv daim ntawv ntawm infrared teeb. Qhov kev siv thev naus laus zis uas siv hluav taws xob hluav taws xob infraition los ntsuas cov khoom siv tsis muaj peev xwm ua cov thev naus laus zis.
Infrared sensor thev naus laus zis yog ib qho kev ua haujlwm nrawm tshaj plaws hauv kev ua lag luam tsis ntev los no, kev lag luam, tub rog, kev lag luam thiab lwm thaj chaw, ua yeeb yam uas tsis tseem ceeb. Infrared, nyob rau hauv essence, yog hom hluav taws xob hluav taws xob yoj, vim tias nws nyob hauv lub teeb liab nyob sab nraud, yog li lub npe infrared. Txhua yam khoom nrog ib qho kub tshaj saud xoom radiates zog rau hauv qhov chaw sab nraud hauv daim ntawv ntawm infrared teeb. Qhov kev siv thev naus laus zis uas siv hluav taws xob hluav taws xob infraition los ntsuas cov khoom siv tsis muaj peev xwm ua cov thev naus laus zis.
Photonic Infrared sensor yog hom sensor uas ua haujlwm los ntawm kev siv lub photon nyhuv ntawm cov hluav taws xob hluav taws xob infriation. Qhov xwm txheej ntawm lub tswv yim no yog hais txog thaum muaj hluav taws xob semiconduct, hloov hluav taws xob ntawm cov tshuab hluav taws xob, ua rau muaj ntau yam tshwm sim hluav taws xob. Los ntsuas cov kev hloov pauv ntawm cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob soobualos, koj tuaj yeem paub lub zog ntawm cov ntsuas hluav taws xob sib xws. Lub ntsiab ntawm photon detectors yog sab hauv photodetector, thav duab sab nraud, dawb cov thauj khoom dawb, QWIP QUANATUM thiab lwm yam. Lub Photodetectors yog txuas ntxiv mus rau hom photoconductive hom, photovolt-generating hom thiab photomagnetcetoelectric hom. Cov yam ntxwv tseem ceeb ntawm Photo Detor yog qhov siab dua, tab sis feem ntau yog qhov kev paub ntau zaus (txhawm rau tswj cov siab, ua kua nitrogen lossis thermoelectric Cov tub yees feem ntau siv los ua kom txias lub photon ntes rau qhov kev ua haujlwm qis dua).
Cov khoom siv ntsuas hluav taws xob feem ntau yog cov yam ntxwv ntawm Green, nrawm, thiab yog ib qho ntawm cov thev naus laus zis kev lag luam ntawm kev ntsuas ntawm kev txheeb xyuas kev ntsuas. Ntau cov roj molecules muaj cov asymmetric diatoms thiab polyatoms muaj cov bands uas tau nqus ntawm qhov sib txawv vim yog cov lwg me me muaj nyob hauv cov khoom ntsuas ntsuas. Raws li kev faib tawm ntawm cov hlua khi ntawm ntau cov roj av thiab lub zog ntawm kev nqus, qhov muaj pes tsawg leeg thiab cov ntsiab lus ntawm cov roj ntsuas tuaj yeem txheeb tau. Infrared roj analyzer yog siv los irradiate nruab nrab nrog ntau yam molecular mediatics, los ntawm kev tsom xam cov roj infrared, thiab raws li kev tsom xam cov roj lossis kev ntsuas siab.
Cov tshuaj ntsuam xyuas ntawm hydroxyl, dej, mg-he-he-he-he-he-he-he-huag, thiab tom qab ntawd lub siab molecular txoj hauj lwm, thiab tom qab ntawd lub siab molecular txoj haujlwm, qhov tob thiab dav ntawm lub spectrum tuaj yeem ntsuas thiab tshuaj ntsuam kom tau txais nws cov tsiaj, Cheebtsam thiab piv ntawm cov hlau loj. Yog li, kev sib sau tshuaj xyuas ntawm cov khoom siv xov xwm tuaj yeem pom tau.
