Classification ntawm infrared sensors
Nov 03, 2021
Lub infrared sensor muaj xws li ib tug optical system, ib tug nrhiav kom tau lub caij thiab ib tug hloov dua siab tshiab Circuit Court. Raws li cov qauv sib txawv, cov tshuab kho qhov muag tuaj yeem muab faib ua ob hom: transmissive thiab reflective. Cov khoom kuaj pom tuaj yeem muab faib ua cov khoom ntsuas thermal thiab photoelectric nrhiav tau raws li txoj cai ua haujlwm. Cov khoom siv thermal feem ntau yog thermistor. Thaum lub thermistor raug rau hluav taws xob infrared, qhov kub thiab txias tau hloov pauv (qhov kev hloov no yuav loj dua lossis me dua, vim tias cov thermistor tuaj yeem muab faib ua qhov zoo ntawm qhov kub thiab txias coefficient thermistors thiab qhov kub tsis zoo coefficient thermistors), Nws dhau los ua cov teeb liab hluav taws xob tso tawm los ntawm cov thermistor. kev hloov pauv Circuit Court. Photoelectric nrhiav pom cov ntsiab lus feem ntau siv cov ntsiab lus photosensitive, feem ntau yog ua los ntawm txhuas sulfide, lead selenide, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy, germanium thiab silicon doped cov ntaub ntawv.
