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) zihlala zikhupha imitha ye-infrared.Le nto ibizwa ngokuba yimitha ye-thermal.Itekhnoloji yokucinga ye-infrared thermal imaging isebenzisa i-micro thermal radiation detector, injongo yokujonga i-optical imaging kunye ne-opto-mechanical scanning system ukufumana imiqondiso yemitha ye-infrared yento eza kulinganiswa, kunye nepateni yokuhanjiswa kwamandla emitha ye-infrared ibonakaliswa kwinto yefotosensitive ye-infrared detector. Emva kokucoca okubonakalayo kunye nokucoca indawo, 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, okhuliswayo kwaye uguqulelwe kwividiyo eqhelekileyo. uphawu, kwaye iboniswe njengomfanekiso we-infrared thermal kwiscreen seTV okanye esweni.
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 we-infrared detector usebenzisa i-infrared detector, i-optical imaging objective kunye ne-opto-mechanical scanning system (itekhnoloji yangoku ye-focal ye-focal plane iphelisa inkqubo yokuskena i-opto-mechanical scanning) ukufumana ipateni yokuhambisa amandla emitha ye-infrared yento eza kulinganiswa kwaye ibonakaliswe kuyo. Isixhobo se-photosensitive se-infrared detector.Phakathi kwenkqubo yokubona kunye nesixhobo sokubona infrared, kukho umatshini wokuskena we-optical-mechanical (i-focal plane yomfanekiso we-thermal 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 kumqondiso wevidiyo oqhelekileyo.
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 esiyinyani, amanye amanyathelo ancedisayo ahlala esetyenziselwa ukunyusa imisebenzi ebonakalayo yesixhobo, njengokulawula ukukhanya komfanekiso kunye nokuchasana, umgangatho wokwenyani. ukulungiswa, umzobo ongeyonyani wecontour kunye nehistogram yemisebenzi yemathematika, ushicilelo, njl.
Iikhamera ze-Thermal imaging zithembisa kwishishini likaxakeka
Xa kuthelekiswa neekhamera zokukhanya ezibonakalayo eziqhelekileyo ezixhomekeke ekukhanyeni kwendalo okanye kwi-ambient ukukhanya kwekhamera, iikhamera zokujonga i-thermal azifuni nakuphi na ukukhanya, kwaye zinomfanekiso ocacileyo oxhomekeke kubushushu be-infrared obuvezwa yinto ngokwayo.Ikhamera yokulinganisa i-thermal ifanelekile nayiphi na indawo yokukhanya 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.
