Ikhamera yomfanekiso we-infrared thermal "nobushushu"

Umgaqo wokusebenza

Ukukhanya kwendalo kuqulunqwe ngamaza okukhanya anobude obuhlukeneyo.Uluhlu olubonakalayo kwiliso lomntu luyi-390-780nm.Amaza ombane amafutshane kune-390nm kwaye ubude kune-780nm akanakuviwa ngamehlo abantu.Phakathi kwazo, amaza e-electromagnetic anobude obungaphantsi kwe-390nm angaphandle kwe-violet ye-spectrum yokukhanya okubonakalayo kwaye abizwa ngokuba yimitha ye-ultraviolet;Amaza ombane amade kune-780nm angaphandle kobomvu bokukhanya okubonakalayo kwaye abizwa ngokuba yi-infrared, kwaye ubude bawo busuka kwi-780nm ukuya kwi-1mm.

I-infrared ngamaza ombane anobude obuphakathi kwee-microwaves kunye nokukhanya okubonakalayo, kwaye inondoqo ofanayo namaza erediyo kunye nokukhanya okubonakalayo.Ngokwendalo, zonke izinto ezinobushushu obungaphezulu kunoziro (-273.15°C) ziqhubeka zikhupha imitha ye-infrared.Le nto ibizwa ngokuba yimitha ye-thermal.Itekhnoloji yokucinga ye-infrared thermal imaging isebenzisa isitshixo sokukhanya semitha ye-thermal, injongo yokujonga ukukhanya kunye nenkqubo yokuskena ye-opto-mechanical ukufumana imiqondiso yemitha ye-infrared yento eza kulinganiswa, kunye nepateni yokuhanjiswa kwamandla emitha ye-infrared ibonakaliswe kwinto yefotosensitive yesixhobo se-infrared. Emva kokucoca okubonakalayo kunye nokuhluzwa kwendawo, oko kukuthi, umfanekiso we-infrared thermal wento elinganisiweyo iskena kwaye igxininise kwiyunithi okanye i-spectroscopic detector, amandla okukhanya kwe-infrared aguqulwa ngumtshina abe ngumqondiso wombane, owandisiweyo kwaye uguqulelwe kwividiyo eqhelekileyo. uphawu, kwaye iboniswe njengomfanekiso we-infrared thermal kwiscreen seTV okanye esweni.

mmyte

I-infrared yi-electromagnetic wave ene-essence efanayo namaza erediyo kunye nokukhanya okubonakalayo.Ukufunyanwa kwe-infrared kukutsiba ekuqondeni komntu indalo.Itekhnoloji esebenzisa isixhobo esikhethekileyo sombane ukuguqula ukuhanjiswa kobushushu kumphezulu wento ibe ngumfanekiso obonakalayo emehlweni omntu kwaye ibonise ukuhanjiswa kobushushu kumphezulu wento ngemibala eyahlukileyo ibizwa ngokuba yi-infrared thermal imaging technology.Esi sixhobo sombane sibizwa ngokuba yi-infrared thermal imager.
Umzobo we-infrared wobushushu usebenzisa isitshixo se-infrared, injongo yokujonga i-optical imaging kunye ne-opto-mechanical scanning system (itekhnoloji yangoku ye-focal ephambili yenqwelomoya isusa inkqubo yokuskena ye-opto-mechanical) ukufumana ipateni yokuhanjiswa kwamandla emitha ye-infrared yento eza kulinganiswa kwaye ibonakaliswe kuyo. Isixhobo se-photosensitive se-infrared detector.Phakathi kwenkqubo yamehlo kunye nesixhobo sokubona infrared, kukho indlela yokuskena ye-optical-mechanical scanning (i-focal plane yomfanekiso oshushu ayinayo le ndlela) ukuskena umfanekiso we-infrared thermal wento eza kulinganiswa kwaye igxininise kwiyunithi okanye i-spectroscopic detector. .Amandla emitha ye-infrared aguqulwa abe ziimpawu zombane sisibonisi, kwaye umfanekiso we-infrared thermal uboniswa kwiscreen seTV okanye esweni emva kokwandiswa nokuguqulwa kwisignali yevidiyo eqhelekileyo.
Olu hlobo lomfanekiso we-thermal luhambelana nentsimi yokusabalalisa i-thermal ebusweni bento;eneneni, yidayagram yokusasazwa komfanekiso oshushu wemitha ye-infrared yenxalenye nganye yento eza kulinganiswa.Ngenxa yokuba isignali ibuthathaka kakhulu, xa ithelekiswa nomfanekiso wokukhanya obonakalayo, ayinayo i-gradation kunye ne-third dimension.Ukuze ugwebe intsimi yokusasazwa kobushushu be-infrared yento ukuba ilinganiswe ngokufanelekileyo kwinkqubo yesenzo sokwenyani, amanye amanyathelo ancedisayo ahlala esetyenziselwa ukwandisa imisebenzi ebonakalayo yesixhobo, njengokulawula ukukhanya komfanekiso kunye nokwahlukileyo, umgangatho wokwenyani. ukulungiswa, umzobo ongeyonyani wecontour kunye nehistogram kwimisebenzi yezibalo, ushicilelo, njl.

Iikhamera ze-Thermal imaging zithembisa kwishishini likaxakeka
Xa kuthelekiswa neekhamera ezikhanyayo ezibonakalayo ezixhomekeke ekukhanyeni kwendalo okanye kwindawo ekuyo ukujonga ikhamera, iikhamera zokujonga i-thermal azifuni kukhanya, kwaye zinomfanekiso ocacileyo oxhomekeke kubushushu be-infrared obuvezwa yinto ngokwayo.Ikhamera yokulinganisa i-thermal ifanelekile nayiphi na indawo yokukhanyisa kwaye ayichaphazeli ukukhanya okunamandla.Iyakwazi ukubona ngokucacileyo kwaye ifumane iithagethi, kwaye ichonge iithagethi ezifihlakeleyo nezifihliweyo kungakhathaliseki imini okanye ubusuku.Ke ngoko, inokuqonda ngokwenene iliso leeyure ezingama-24.
