    Umgaqo oSebenzayo weThermopile Infrared Sensor-Isiphumo seThermoelectric

    Iziphumo ze-Thermoelectric (Iziphumo zeSeebeck)

    Ukuba izinto ezimbini ezahlukeneyo okanye izinto A kunye no-B abanemathiriyeli efanayo ngelixa benomsebenzi owahlukileyo womsebenzi, xa beqhagamshelene kwisiphelo esishushu (Indawo eshushu yeJunction), bavulwa kwindawo ebandayo (Indawo yokubanda yeCold Junction), kunye nomgangatho wobushushu phakathi kobushushu isiphelo kunye nesiphelo sokubanda yi-ΔTHC, Ke ekupheleni kokubandayo kuyakubakho amandla e-thermoelectromote force Vngaphandle.

    Xa imitha yangaphakathi ye-infrared icacisa indawo yokutsalwa kwesitshisi, indawo yokufunxa ithatha imitha ye-infrared kwaye iyiguqula ibe ngamandla obushushu. Umgangatho wobushushu uya kwenziwa kwindawo eshushu yokudibana kunye nendawo yokubambana ebandayo. Ngokusebenzisa isiphumo seSeebeck sezinto ze-thermocouple, igradient yeqondo lobushushu inokuguqulwa ibe sisiphumo sombane.

    Iziphumo ze-Thermoelectric (Iziphumo zeSeebeck)

    Icebo lokucoca ulwelo (uphawu lwecebo lokucoca ulwelo lukhetho): khetha ibhendi ye-infrared, thintela amanye amaza okukhanya ukuze uchaphazele isivamvo

    Ikephu: ubume bokuxhasa oomatshini bokucoca i-IR

    I-TPS Chip: ukuqonda isignali ye-infrared edlula kwisihluzi se-IR

    Okubhalwe ngasentla kwephepha: uyilo oluxhasayo lwesixhobo se-chip

    I-Chip Thermistor (Ngokuzithandela): jonga ubushushu bendawo ehlangana kwindawo ebandayo ye-TPS chip

    I-ASIC yokuqhubekeka kwesekethe (ngokunganyanzelekanga, ukuphuma komqondiso)

    Kuyabonakala ukuba umgaqo osebenzayo we-chip ye-thermopile sensor kukuguqula okungokwasemzimbeni kabini "kombane oshushu-wombane". Nayiphi na into engaphezulu kwe-zero (kubandakanya umzimba womntu) ikhupha imitha ye-infrared, ukuba ukhetha ubude obufanelekileyo ngokusebenzisa isihluzo se-infrared (5-14μm window window), xa izinto ezibukhali ze-infrared kwi-chip zithatha ubushushu be-infrared kwaye ziguqula ukukhanya zibe bubushushu , okukhokelela ekunyukeni kobushushu bommandla wokufunxa, umahluko wobushushu phakathi kwendawo yokufunxa kunye nendawo yokubanda ebandayo iguqulwa ibe sisiphumo sevolthi ngokusebenzisa amakhulu eeseti zonxibelelwano oluncinci lwe-thermocouples, kwaye uphawu lwe-infrared lufunyenwe emva kokuphuma kombane yenziwe.

    Ukubona kulwakhiwo, i-Sunshine Technologies ye-infrared sensor ye-infrared yahlukile kwiimveliso eziqhelekileyo, ubume bayo "bungaphandle". Kukho ubunzima obuphambili kwezobuchwephesha kolu lwakhiwo, oko kukuthi, indlela yokubeka umaleko we-1μm kwifilimu yokumisa kumda we-1 mm kuphela2, kunye nokuqinisekisa ukuba umboniso bhanya-bhanya unenqanaba elaneleyo lokuguqula ukuguqula ukukhanya kwe-infrared kwisiphumo sombane wombane, ukuze kuhlangatyezwane neemfuno zamandla esignali. Ngokuchanekileyo kungenxa yokuba i-Sunshine Technologies iphumelele kwaye iyazi kakuhle le teknoloji isisiseko enokuthi yaphule ulawulo lwexesha elide lweemveliso zangaphandle ngesibetho esinye.
