Amamodeli ajwayelekile ezinzwa ze-infrared zamakhamera wokuthwebula ashisayo

I-thermistor ye-NTC ingummeleli ojwayelekile wezinzwa ze-infrared zohlobo lwe-thermistor. Inesakhiwo esilula kanye nenzuzo ephawulekayo, futhi yayisetshenziswa kabanzi emishinini yokucabanga eshisayo yokuqala. Umgomo wayo wokusebenza usekelwe kusici sokumelana ne-thermistor eshintsha nezinga lokushisa. Lapho ithola imisebe, izinga lokushisa layo liyakhuphuka, futhi nenani lokumelana liyashintsha ngokufanele, ngaleyo ndlela ithole ukushuba kwemisebe ye-infrared. Kodwa-ke, ukuzwela kanye nesivinini sokuphendula sale modeli kunqunyelwe, futhi kancane kancane ishintshwa ezimeni lapho kudingeka khona ukunemba okuphezulu nesivinini sokuphendula. Nokho, isengadlala indima kwezinye izinhlelo zokusebenza eziyisisekelo eziyizindleko ezibucayi futhi ezingadingi ukunemba okuphezulu, njengamadivayisi alula okuqapha izinga lokushisa.

Le nzwa ye-thermopile evela kwa-Heimann yenza kahle kakhulu ukubona ngokushesha kwezimboni nokuqapha ilangabi. Iqukethe ama-thermocouples amaningi axhunywe ochungechungeni. Uma kusetshenziswa imisebe ye-infrared, umehluko wezinga lokushisa ukhiqizwa emikhawulweni yomibili, amandla we-thermoelectric akhiqizwa ngokusekelwe kumphumela we-Seebeck. Ukuqina kwemisebe ye-infrared kunqunywa ngokulinganisa amandla kagesi we-thermoelectric. Ekukhiqizeni izingxenye zemoto, ingakwazi ukubona ngokushesha ukuthi izinga lokushisa eliphezulu lezingxenye lifana yini, liqinisekisa ikhwalithi yomkhiqizo; ezimeni zokuqapha ilangabi, lingasabela ngokushesha ezinguqukweni ze-infrared yelangabi futhi likhiphe i-alamu ngesikhathi. Ukusabela kwayo okusheshayo nokuzinza okuhle kuyenza ibe ukukhetha okuhle kwezimo ezinjalo.

Uchungechunge lwe-ULIS luyizinzwa ze-infrared zohlobo lwe-microbolometer. Isebenza ngokusebenzisa isici se-conductivity yezinto ze-semiconductor ezishintsha ngokushisa. Ngemuva kokuthola imisebe ye-infrared, izinga lokushisa liyakhuphuka, ukuqhutshwa kukagesi kwe-semiconductor kuyashintsha, okuholela ekushintsheni kwenani lokumelana bese kubalwa amandla emisebe ye-infrared. Ekuqaphelweni kwezokuphepha, ngokuzwela okuphezulu nokulungiswa okuphezulu, ingakwazi ukuthwebula ngokucacile umehluko ocashile wezinga lokushisa ebusuku, isize ukuphepha ukuthola izinsongo ezingaba khona ngesikhathi; ekuxilongweni kwezokwelapha, ingakwazi ukubona izinga lokushisa elingavamile lomzimba womuntu, isize ekuxilongweni kwezifo; emkhakheni wocwaningo lwesayensi ihlinzeka ngedatha yokushisa enembayo ephezulu ukuze kufundwe ukusebenza kwe-thermal material. Okugqamile kwezobuchwepheshe ubuchwepheshe bayo be-microbolometer obuvuthiwe, futhi ukuma kwemakethe kumaphakathi kuya ekupheleni, kusetshenziswa kabanzi emikhakheni yobungcweti enezidingo eziphezulu zekhwalithi yesithombe esishisayo.

Le modeli ivame ukusetshenziswa ezimeni zokulinganisa izinga lokushisa ukuze kubonwe ubuso. Inokunemba kwesilinganiso sokushisa okuphezulu nokuzinza. Ingakwazi ukubona ngokushesha nangokunembile izinga lokushisa lomzimba womuntu, futhi ihlanganiswe nobuchwepheshe bokuqashelwa kwesithombe, ingafinyelela ukuhlanganiswa kokuqashelwa kobuso nokutholwa kwezinga lokushisa, elisetshenziswa kabanzi ezinhlelweni zokulawula ukufinyelela, ukuhlolwa kokushisa kwezindawo zomphakathi kanye nezinye izimo, ukuthuthukisa ngokuphumelelayo ukusebenza kahle kokutholwa nokuphathwa. Inzuzo yayo yobuchwepheshe isesilinganisweni esinembile sezinga lokushisa kanye nokuhlanganiswa kokuqashelwa kwesithombe okuphumelelayo, ikakhulukazi ebhekene nokuvikeleka, ukuvimbela ubhubhane lwezempilo yomphakathi nezinye izimakethe ezifuna ubunikazi bezisebenzi nokutholwa kwezinga lokushisa.

Lona uphenyo lwenzwa ye-infrared thermal imaging ephezulu enebanga lokulinganisa izinga lokushisa elingu- -40 kuya ku-85℃, kusetshenziswa ukupakisha okungu-TO39. Ihlanganisa inombolo enkulu yamaphikseli e-microometer, ekwazi ukuhlinzeka ngedatha ye-imaging ye-thermal-resolution ephezulu. Ivame ukusetshenziswa ekuhlolweni kwezimboni, ukuqapha izinga lokushisa ezindlini ezihlakaniphile, nokuhlaziya ukushisa ocwaningweni lwesayensi yocwaningo futhi ingakala ngokunembile ukusatshalaliswa kwezinga lokushisa okungaphezulu kwezinto, inikeze ukwesekwa kwedatha okuthembekile kwezinhlelo zokusebenza ezihlobene. Le modeli ibonakala ngokunemba okuphezulu kanye nebanga elibanzi lokulinganisa izinga lokushisa, ibekwe njengomkhiqizo ophakathi nendawo ukuya phezulu ezinkambini zocwaningo lwezimboni nesayensi, ihlangabezana nezinhlelo zokusebenza ezinezidingo eziqinile zokunemba kwedatha yesithombe esishisayo.

I-AMG8833 iyinzwa yokucabanga eshisayo engu-8x8 pixel ihlangene ngosayizi futhi kulula ukuyihlanganisa kumadivayisi amancane ahlukahlukene. Ingakwazi ukuthwebula ngokushesha isithombe esishisayo esinezinhlangothi ezimbili sento. Nakuba i-pixel iphansi uma kuqhathaniswa, isebenza kahle kwezinye izinhlelo zokusebenza ezingadingi ukulungiswa okuphezulu futhi igxile ekwenziweni okuncane kwedivayisi, njengokuqapha izinga lokushisa lomzimba kumadivayisi agqokekayo kanye nokuzwa izinga lokushisa kwemvelo kumadivayisi amancane asekhaya. Izinzuzo zayo ezivelele usayizi wayo ohlangene kanye nezindleko eziphansi, ikakhulukazi ebhekene nemakethe yabathengi ezwelayo kusayizi wedivayisi nezindleko.

I-GST320 isebenzisa umtshina wendiza ogxilile ongapholi ongu-320x240 owenziwe nge-vanadium oxide, onokufana okuphezulu nokuhle kwezinga lokushisa. Isetshenziswa kakhulu ekuqapheni ezokuphepha, ekuhloleni i-patrol yamandla, nezinye izinkambu, futhi ingathwebula ngokusobala ukusatshalaliswa kwezinga lokushisa kwento eqondiwe kusiza abasebenzi ukuthi bathole ngokushesha izingozi zokuphepha ezingaba khona.

Uchungechunge lwe-TMR lwe-Dali Technology luhlanganisa amamodeli ahlukahlukene, anokucaca okuphezulu nobubanzi obuguqukayo. Lolu chungechunge lwemikhiqizo lusebenzisa ubuchwepheshe be-microbolometer obuthuthukisiwe futhi lungahlinzeka ngezithombe ezicacile nezizinzile ze-imaging ezishisayo ezindaweni eziyinkimbinkimbi. Idlala indima ebalulekile ekuvimbeleni umlilo, ukuphepha okuphezulu, nezinye izinkambu, futhi ingathola ngokushesha izingozi zomlilo nezimo ezingavamile ngokuqapha izinga lokushisa lezindawo ezinkulu. Uchungechunge lwe-TMR, olusebenza kahle kakhulu, lubekwe emakethe esezingeni eliphezulu, luhlangabezana nezinhlelo zokusebenza ezinezidingo eziphakeme kakhulu zekhwalithi yokuthwebula okushisayo nokuthembeka.

Lawa mamodeli ajwayelekile ezinzwa ze-infrared adlala ukhiye kumakhamera wesithombe esishisayo emikhakheni ehlukene enezici zazo. Ngokuthuthuka okuqhubekayo kobuchwepheshe, amamodeli enzwa ye-infrared asebenza kahle kakhulu futhi ahlukile azoqhubeka nokuvela, akhuthaze ukuthuthukiswa okuqhubekayo kanye nokusetshenziswa kobuchwepheshe be-imaging obushisayo.
