Umgaqo oSebenzayo we-Thermopile Infrared Sensor-Thermoelectric Effect

I-Thermoelectric Effect (Seebeck Effect)

Ukuba izinto ezimbini ezahlukeneyo okanye izinto A kunye B ezinemathiriyeli efanayo ngelixa umsebenzi ezahlukeneyo umsebenzi, xa ziqhagamshelwe ekupheleni eshushu (Hot Junction Area), ivulwe kwisiphelo esibandayo (Cold Junction Area), kunye neqondo lobushushu phakathi eshushu. isiphelo kunye nesiphelo esibandayo yi ΔT_HC, ke ekupheleni okubandayo kuya kubakho amandla e-thermoelectromotive V_ngaphandle.

Xa imitha ye-infrared yangaphandle ikhupha indawo yokufunxa ye-detector, indawo yokufunxa ifunxa imitha ye-infrared kwaye iyiguqule ibe ngamandla obushushu.I-gradient yeqondo lokushisa iya kuveliswa kwindawo yokudibanisa eshushu kunye nommandla obandayo.Ngokusebenzisa i-Seebeck Effect yezinto ze-thermocouple, i-gradient yobushushu inokuguqulwa ibe yimveliso yesignali yombane.

I-Thermoelectric Effect (Seebeck Effect)

Hluza(uphawu lwesihluzo se-IR sinokuzikhethela): khetha ibhendi ye-infrared, nqanda enye i-wavelength yokukhanya ukuchaphazela inzwa.

Cap: Ulwakhiwo lomatshini oluxhasayo lwesihluzo se-IR.

TPS Chip: Ukuva isignali ye-infrared edlula kwisihluzo se-IR.

Okubhalwe ngasentla kwekhasi: Ulwakhiwo lomatshini oluxhasayo lwetshiphu.

Chip Thermistor(Ngokhetho): jonga ubushushu bendawo yesiphambuka esibandayo setshiphu ye-TPS.

I-ASIC yokucubungula i-chip yesekethe(ukhetho, imveliso yesignali yokulinganisa): ukulungelelanisa isignali ye-analog yemveliso ye-TPS chip.

Ingabonwa ukuba umgaqo osebenzayo we-thermopile sensor chip ukuguqulwa komzimba kabini "kwe-light-thermal-electricity".Nayiphi na into engaphezulu kuka-zero ngokupheleleyo (kubandakanywa nomzimba womntu) ikhupha imitha ye-infrared, ukuba ukhetha ubude obufanelekileyo ngesihluzo se-infrared (5-14μm band window), xa imathiriyeli ebuthathaka ye-infrared kwitshiphu ifunxa ubushushu be-infrared kwaye ijika ukukhanya kube bubushushu. , okukhokelela ekunyukeni kwamaqondo obushushu kwindawo yokufunxa, umahluko weqondo lobushushu phakathi kwendawo yokufunxa kunye nendawo ebandayo yesiphambuka iguqulwa ibe yimveliso yamandla ombane ngamakhulu eeseti zoqhagamshelo lwe-micro thermocouples series, kunye nesignali ye-infrared ichongiwe emva kokuphuma kombane. yenziwe.

Ukubona kwisakhiwo, i-Sunshine Technologies's thermopile infrared sensor yahlukile kwiimveliso eziqhelekileyo, isakhiwo sayo "singenanto ngaphandle".Kukho ubunzima obuphambili bobugcisa kwesi sakhiwo, oko kukuthi, indlela yokubeka umaleko wefilimu yokunqunyanyiswa kwe-1μm kwindawo eyi-1 mm kuphela.², kwaye uqinisekise ukuba ifilimu inokuba nesantya esaneleyo sokuguqula ukuguqula ukukhanya kwe-infrared kwimveliso yesignali yombane, ukuze ihlangabezane neemfuno zamandla omqondiso wenzwa.Kungenxa yokuba i-Sunshine Technologies yoyisile kwaye yazuza ubuchwephesha obungundoqo ukuba inokophula ukulawulwa kwexesha elide kweemveliso zangaphandle ngestroke enye.
