Mfundo yogwira ntchito
Kuwala kwachilengedwe kumapangidwa ndi mafunde owala okhala ndi kutalika kosiyanasiyana.Mtundu wowoneka ndi maso amunthu ndi 390-780nm.Mafunde a electromagnetic aafupi kuposa 390nm komanso otalika kuposa 780nm sangamvedwe ndi maso amunthu.Pakati pawo, mafunde a electromagnetic okhala ndi kutalika kosachepera 390nm ali kunja kwa violet ya kuwala kowoneka bwino ndipo amatchedwa kuwala kwa ultraviolet;Mafunde a electromagnetic aatali kuposa 780nm ali kunja kwa kuwala kowoneka bwino ndipo amatchedwa infrared, ndipo kutalika kwake kumayambira 780nm mpaka 1mm.
Infrared ndi mafunde a electromagnetic okhala ndi kutalika kwa mafunde pakati pa ma microwave ndi kuwala kowoneka, ndipo ali ndi mawonekedwe ofanana ndi mafunde a wailesi ndi kuwala kowoneka.M'chilengedwe, zinthu zonse zomwe kutentha kwake kuli kopitilira ziro (-273.15 ° C) kumawunikira mosalekeza cheza cha infuraredi.Chodabwitsa ichi chimatchedwa kutentha kwa kutentha.Tekinoloje yaukadaulo ya infrared thermal imaging imagwiritsa ntchito chowunikira chowunikira ma radiation, cholinga chowunikira komanso makina owonera makina kuti alandire ma radiation a infrared a chinthu chomwe chiyenera kuyezedwa, ndipo njira yowunikira mphamvu ya infrared radiation imawonetsedwa ku chithunzi cha chowunikira cha infrared. pambuyo kusefa kwa spectral ndi kusefa kwapakatikati, ndiye kuti, chithunzi chamoto cha infrared cha chinthu choyezedwa chimafufuzidwa ndikuyang'ana pa unit kapena spectroscopic detector, mphamvu yowunikira infrared imasinthidwa ndi chowunikira kukhala chizindikiro chamagetsi, chomwe chimakulitsidwa ndikusinthidwa kukhala kanema wamba. chizindikiro, ndi kuwonetsedwa ngati chithunzi chotentha cha infuraredi pa TV kapena polojekiti.
Infrared ndi mafunde a electromagnetic omwe ali ndi mawonekedwe ofanana ndi mafunde a wailesi ndi kuwala kowoneka.Kupezeka kwa infrared ndikudumpha pakumvetsetsa kwaumunthu kwachilengedwe.Ukadaulo womwe umagwiritsa ntchito chipangizo chapadera chamagetsi kuti usinthe kugawa kwa kutentha pamwamba pa chinthu kukhala chithunzi chowoneka ndi maso a munthu ndikuwonetsa kugawa kwa kutentha pamwamba pa chinthucho mumitundu yosiyanasiyana kumatchedwa ukadaulo wa infrared thermal imaging.Chipangizo chamagetsi chimenechi chimatchedwa infrared thermal imager.
Infrared thermal imager imagwiritsa ntchito infrared detector, optical imaging imaging and opto-mechanical scanning system (ukadaulo waposachedwa wa ndege wotsogola umachotsa opto-mechanical scanning system) kuti alandire njira yogawa mphamvu ya infrared ya chinthu chomwe chiyenera kuyezedwa ndikuchiwonetsa ku Chithunzi cha chowunikira cha infrared.Pakati pa optical system ndi infrared detector, pali makina owonera makina (chojambula chotenthetsera ndege sichikhala ndi makinawa) kuti ajambule chithunzi chotenthetsera cha chinthu chomwe chiyenera kuyezedwa ndikuchiyang'ana pa unit kapena spectroscopic detector. .Mphamvu yowunikira ya infrared imasinthidwa kukhala ma siginecha amagetsi ndi chowunikira, ndipo chithunzi chotenthetsera cha infrared chimawonetsedwa pazenera la TV kapena kuwunika pambuyo pakukulitsa ndikusintha kukhala siginecha yanthawi zonse.
Mtundu uwu wa chithunzi chotenthetsera umagwirizana ndi gawo logawira kutentha pamwamba pa chinthucho;kwenikweni, ndi chithunzi chotenthetsera chogawa cha radiation ya infuraredi ya gawo lililonse la chinthu chomwe chiyenera kuyezedwa.Chifukwa chizindikirocho ndi chofooka kwambiri, poyerekeza ndi chithunzi chowala chowoneka, sichikhala ndi gradation ndi gawo lachitatu.Pofuna kuweruza gawo la infuraredi yogawa kutentha kwa chinthucho kuti chiyezedwe bwino muzochitika zenizeni, njira zina zothandizira nthawi zambiri zimagwiritsidwa ntchito kuonjezera ntchito zothandiza za chipangizocho, monga kulamulira kwa chithunzithunzi chowala ndi kusiyanitsa, zenizeni zenizeni. kuwongolera, mawonekedwe onyenga amitundu yojambula ndi histogram pamachitidwe a masamu, kusindikiza, ndi zina.
Makamera oyerekeza otenthetsera akulonjeza mumakampani azadzidzidzi
Poyerekeza ndi makamera owoneka bwino achikhalidwe omwe amadalira kuwala kwachilengedwe kapena kozungulira kuti athe kuyang'anira kamera, makamera oyerekeza otenthetsera safuna kuwala kulikonse, ndipo amatha kujambula momveka bwino kudalira kutentha kwa infrared komwe kumawulutsidwa ndi chinthucho.Kamera yojambula yotentha ndiyoyenera malo aliwonse owunikira ndipo samakhudzidwa ndi kuwala kolimba.Imatha kuzindikira bwino ndikupeza zomwe mukufuna, ndikuzindikira zobisika komanso zobisika mosasamala usana kapena usiku.Chifukwa chake, imatha kuzindikira kuwunika kwa maola 24.
