Umgomo Osebenzayo we-Thermopile Infrared Sensor - Thermoelectric Effect

I-Thermoelectric Effect(Seebeck Effect)

Uma izinto ezimbili ezihlukene noma izinto u-A no-B ezinento efanayo ngenkathi zinomsebenzi ohlukile, lapho zixhunywe ekugcineni okushisayo (Indawo Yendawo Eshisayo), zivulwa ekugcineni okubandayo (Indawo Yokuhlangana Okubandayo), kanye negradient yezinga lokushisa phakathi kokushisayo. isiphetho nesiphetho esibandayo ngu-ΔT_HC, ngakho ekugcineni okubandayo kuzoba namandla we-thermoelectromotive V_ngaphandle.

Lapho imisebe ye-infrared yangaphandle ikhanyisa indawo yokumunca yomtshina, indawo yokumunca idonsa imisebe ye-infrared futhi iyiguqule ibe amandla okushisa.I-gradient yezinga lokushisa izokhiqizwa endaweni ye-hot junction nasendaweni ebandayo.Ngomphumela we-Seebeck we-thermocouple impahla, izinga lokushisa lingaguqulwa libe okukhipha isignali kagesi.

I-Thermoelectric Effect (I-Seebeck Effect)

Hlunga(isici sesihlungi se-IR singakhethwa): khetha ibhendi ye-infrared, gwema obunye ubude beza beza bokukhanya ukuze buthinte inzwa.

Cap: isakhiwo esisekelayo somshini wesihlungi se-IR.

I-TPS Chip: ukuzwa isignali ye-infrared edlula kusihlungi se-IR.

Unhlokweni: isakhiwo esisekelayo se-chip.

I-Chip Thermistor(Ongakukhetha): qapha izinga lokushisa elibandayo lendawo yesiphambano se-TPS chip.

I-ASIC yokucubungula i-chip yesekethe(ongakukhetha, okukhiphayo kwesignali yesimo): ukubeka isimo isignali yokuphuma kwe-analog ye-chip ye-TPS.

Kungabonakala ukuthi isimiso sokusebenza se-chip sensor ye-thermopile ukuguqulwa okuphindwe kabili ngokomzimba kwe-"light-thermal-electricity".Noma iyiphi into engaphezu kukaziro ophelele (kuhlanganise nomzimba womuntu) ikhipha imisebe ye-infrared, uma ukhetha ubude begagasi obufanele ngesihlungi se-infrared (5-14μm band window), lapho into ezwelayo ye-infrared ku-chip imunca ukushisa kwe-infrared futhi iguqule ukukhanya kube ukushisa. , okuholela ekukhuphukeni kwezinga lokushisa endaweni yokumunca, umehluko wezinga lokushisa phakathi kwendawo yokumunca nendawo ebandayo yokuhlanganisa iguqulwa ibe amandla kagesi ngamakhulu amasethi ochungechunge lwama-micro thermocouples oxhumano lochungechunge, futhi isignali ye-infrared itholakele ngemva kokukhishwa kwe-voltage. kukhiqizwa.

Ngokubona esakhiweni, inzwa ye-infrared ye-Sunshine Technologies ye-infrared ihlukile emikhiqizweni evamile, ukwakheka kwayo "akunalutho".Kunobunzima obubalulekile bobuchwepheshe balesi sakhiwo, okungukuthi, indlela yokubeka ungqimba lwefilimu yokumiswa eyi-1μm ewugqinsi endaweni eyi-1 mm kuphela.², futhi uqinisekise ukuthi ifilimu ingaba nezinga lokuguqulwa elanele ukuze iguqule ukukhanya kwe-infrared kube okukhipha isignali kagesi, ukuze ihlangabezane nezidingo zamandla esignali zenzwa.Kungenxa yokuthi i-Sunshine Technologies inqobe futhi yazuza lobu buchwepheshe obuyisisekelo okwenza ukuthi ikwazi ukunqamula ukubusa kwemikhiqizo yangaphandle isikhathi eside ngesikhathi esisodwa.
