Isimiso sokusebenza
Ukukhanya kwemvelo kwakhiwe ngamaza okukhanya anamaza ahlukene.Ububanzi obubonakalayo ngeso lomuntu buyi-390-780nm.Amagagasi kagesi mafushane kuno-390nm futhi amade kuno-780nm awakwazi ukuzwakala emehlweni omuntu.Phakathi kwawo, amagagasi kagesi anobude obungaphansi kuka-390nm angaphandle kwe-violet ye-spectrum yokukhanya ebonakalayo futhi abizwa ngokuthi imisebe ye-ultraviolet;amaza kagesi amade kuno-780nm angaphandle kobomvu bokukhanya okubonakalayo futhi abizwa nge-infrared, futhi ubude bawo begagasi busukela ku-780nm kuye ku-1mm.
I-infrared igagasi kazibuthe elinobude beza phakathi kwama-microwave nokukhanya okubonakalayo, futhi linomongo ofanayo namaza omsakazo nokukhanya okubonakalayo.Emvelweni, zonke izinto izinga lokushisa lazo lingaphezu kukaziro (-273.15°C) ngokuqhubekayo zikhipha imisebe ye-infrared.Lesi simo sibizwa ngokuthi imisebe eshisayo.Ubuchwepheshe bokucabanga nge-infrared thermal imaging busebenzisa umtshina wemisebe emincane eshisayo, inhloso ye-optical imaging kanye nesistimu yokuskena ye-opto-mechanical ukuthola amasignali emisebe ye-infrared yento ezokalwa, kanye nephethini yokusabalalisa amandla emisebe ye-infrared egxilile iboniswa kusici se-photosensitive se-infrared detector. ngemuva kokuhlunga okubonwayo kanye nokuhlunga kwendawo, okungukuthi, isithombe esishisayo se-infrared sento elinganisiwe siyaskeniwa futhi sigxile kuyunithi noma umtshina we-spectroscopic, amandla emisebe ye-infrared aguqulwa umtshina abe isignali kagesi, ekhuliswayo futhi iguqulelwe kuvidiyo ejwayelekile. isignali, futhi ivezwe njengesithombe esishisayo se-infrared kusikrini se-TV noma kumonitha.
I-infrared igagasi ozibuthe kagesi elinomongo ofanayo namaza omsakazo nokukhanya okubonakalayo.Ukutholwa kwe-infrared kuwukugxuma ekuqondeni komuntu imvelo.Ubuchwepheshe obusebenzisa idivayisi ye-elekthronikhi ekhethekile ukuguqula ukusabalalisa kwezinga lokushisa endaweni engaphezulu yento ibe isithombe esibonakala emehlweni omuntu futhi ebonisa ukusatshalaliswa kwezinga lokushisa ebusweni bento ngemibala ehlukene bubizwa ngokuthi ubuchwepheshe be-infrared thermal imaging.Lesi sisetshenziswa sikagesi sibizwa nge-infrared thermal imager.
Isithombe se-infrared thermal sisebenzisa umtshina we-infrared, inhloso ye-optical imaging kanye nesistimu yokuskena ye-opto-mechanical (ubuchwepheshe bamanje obuphambili bendiza obugxilile buqeda isistimu yokuskena ye-opto-mechanical) ukuthola iphethini yokusabalalisa amandla emitha ye-infrared yento ezokalwa futhi ibonise Ingxenye ye-photosensitive yomtshina we-infrared.Phakathi kwesistimu yokubona kanye nomtshina we-infrared, kukhona indlela yokuskena ye-optical-mechanical (i-focal plane imager thermal ayinayo le mishini) ukuze iskene isithombe esishisayo se-infrared sento ezolinganiswa futhi igxiliswe kuyunithi noma umtshina we-spectroscopic. .Amandla okukhanya kwe-infrared aguqulwa abe amasignali kagesi ngumtshina, futhi isithombe esishisayo se-infrared siboniswa kusikrini se-TV noma kuqashwe ngemva kokukhulisa nokuguqulwa kusignali yevidiyo evamile.
Lolu hlobo lwesithombe esishisayo luhambisana nenkambu yokusabalalisa okushisayo ebusweni bento;empeleni, iwumdwebo wokusabalalisa isithombe esishisayo semisebe ye-infrared yengxenye ngayinye yento ezolinganiswa.Ngenxa yokuthi isignali ibuthakathaka kakhulu, uma iqhathaniswa nesithombe esikhanyayo esibonakalayo, ayinakho ukuhleleka kanye nobukhulu besithathu.Ukuze wahlulele inkambu yokusabalalisa ukushisa kwe-infrared yento ezolinganiswa ngempumelelo kakhulu enqubweni yesenzo sangempela, ezinye izinyathelo ezisizayo zivame ukusetshenziselwa ukukhulisa imisebenzi engokoqobo yethuluzi, njengokulawula ukukhanya kwesithombe nokugqama, izinga langempela. ukulungiswa, i-contour yokudweba kombala okungamanga kanye ne-histogram yokusebenza kwezibalo, ukuphrinta, njll.
Amakhamera we-imaging ashisayo ayathembisa embonini yezimo eziphuthumayo
Uma kuqhathaniswa namakhamera avamile okukhanya abonakalayo ancike ekukhanyeni kwemvelo noma kwe-ambient ukuze kuqashwe ikhamera, amakhamera ezithombe ezishisayo awadingi ukukhanya, futhi angakwazi isithombe esicacile sincike ekushiseni kwe-infrared okukhishwa into ngokwayo.Ikhamera yesithombe esishisayo ifaneleka kunoma iyiphi indawo yokukhanyisa futhi ayithinteki ukukhanya okuqinile.Ingathola ngokucacile futhi ithole okuqondiwe, futhi ikhombe okuqondiwe okucashile nokufihliwe kungakhathaliseki ukuthi kusemini noma ebusuku.Ngakho-ke, ingakwazi ukubona ukuqapha kwamahora angu-24 ngempela.
