Ukusetshenziswa Kwezempi Kwe-Infrared Thermal Imaging
Uma kuqhathaniswa nesistimu ye-radar, isistimu ye-infrared thermal imaging inokulungiswa okuphezulu, ukucasha okungcono, futhi ayithinteki kakhulu ekuphazamisekeni kwe-elekthronikhi. Uma iqhathaniswa nesistimu yokukhanya ebonakalayo, inezinzuzo zokukwazi ukubona ukufihla, ukusebenza imini nobusuku, kanye nokuthinteka kancane kwesimo sezulu. Ngakho-ke, isetshenziswa kabanzi kwezempi. Izicelo zayo eziyinhloko yilezi:
Ukubona ebusuku kwe-infrared
I-infraredumbono ebusukuamadivayisi asetshenziswa ekuqaleni kwawo-1950 wonke angamadivayisi asebenzayo okubona ebusuku kwe-infrared, ngokuvamile asebenzisa amashubhu okushintsha isithombe seso lefoni njengabamukeli, futhi ibhendi esebenzayo icishe ibe yi-micron engu-1. Amathangi, izimoto kanye nemikhumbi eqhele ngamakhilomitha ayi-10.
Imishini yesimanje ye-infrared yokubona ebusuku ikakhulukazi ifaka i-infraredikhamera eshisayo(okwaziwa nangokuthi amasistimu okubona phambili kwe-infrared), ama-TV e-infrared kanye namadivayisi asebenzayo asebenzayo okubona ebusuku kwe-infrared. Phakathi kwazo, i-infrared thermal imager iyithuluzi elimele le-infrared elibona ebusuku.
Isistimu ye-optical-mechanical scanning infrared imaging eyakhiwe yi-United States ngasekupheleni kwawo-1960 ihlinzeka ngezindlela zokubuka indiza endiza ebusuku futhi indize ngaphansi kwezimo zezulu ezinzima. Isebenza ku-8-12 micron range futhi ngokuvamile isebenzisa i-mercury cadmium telluride photon detectors ukuthola imisebe, i-liquid nitrogen refrigeration. Ukusebenza kwayo okuhlakaniphile nobuchwepheshe kuwuhlelo lobukhulu obungaphezulu kwamadivayisi asebenzayo okubona ebusuku kwe-infrared. Ebusuku, abantu ebangeni elingu-1 ikhilomitha bangabonwa, amathangi nezimoto ebangeni elingamakhilomitha angama-5 kuye kwayi-10, nemikhumbi engaphakathi kobubanzi obubonakalayo.
Lolu hloboikhamera eshisayoiye yathuthukiswa izikhathi eziningana. Ekuqaleni kwawo-1980, izinhlelo ezimisiwe nezihlanganisiwe zase zivele emazweni amaningi. Abaqambi bangakhetha izingxenye ezihlukene ngokwezidingo futhi bahlanganise amakhamera wokuthwebula ashisayo adingekayo, inqobo nje uma ibutho lebutho linemishini elula, elula, eyongayo futhi eguquguqukayo yokubona ebusuku.
I-infraredimishini yokubona ebusukuisetshenziswe kabanzi emabuthweni asemhlabeni, olwandle nasemoyeni. Okufana nemishini yokubuka yokushayela amathangi ebusuku, izimoto, izindiza, imikhumbi, njll., izinto ezibonwa ebusuku zezikhali ezilula, amasistimu okulawula umlilo emicibisholo ecitshwayo nezikhali, ukugadwa komngcele kanye nemishini yokubuka enkundleni yempi, kanye nemishini yokuhlola umuntu ngamunye. Ngokuzayo, kuzothuthukiswa isistimu yokuthwebula eshisayo eyakhiwe ngendiza egxile ebheke phezulu, futhi ukusebenza kwayo kobuhlakani nobuchwepheshe kuzothuthukiswa nakakhulu.
Isiqondiso se-infrared
Ngokuthuthukiswa kobuchwepheshe be-infrared, isistimu yokuqondisa ye-infrared iya ngokuya iphelele. Ngemuva kweminyaka yawo-1960s, amasistimu we-infrared asebenzayo aseyatholakala kumafasitela amathathu asemoyeni. Indlela yokuhlasela ithuthukile kusukela ekulandeleni umsila kuya ekuhlaseleni kwendawo yonke. Indlela yokuqondisa futhi inesiqondiso esigcwele se-infrared (isiqondiso somthombo wamaphuzu nokuqondisa kwesithombe) kanye nesiqondiso esiyinhlanganisela (isiqondiso se-infrared). /TV, umyalo we-infrared/radio, infrared/radar point source guide system isetshenziswe kabanzi kunqwaba yemicibisholo enamaqhinga efana nokusuka emoyeni, ukuya emoyeni, ugu ukuya emkhunjini kanye nomkhumbi ukuya emkhunjini. imicibisholo.
I-infrared reconnaissance
Imishini yokuhlola i-infrared yaphansi (amanzi), umoya nendawo, okuhlanganisa ikhamera eshisayo, izikena ze-infrared, itheleskopu ye-infrared namasistimu eimaging e-infrared asebenzayo, njll. Imishini yokuhlola ephansi ye-infrared ikakhulukazi iyisithombe se-infrared esishisayo kanye nedivayisi esebenzayo yokubona ebusuku.
I-infrared periscope esetshenziswa imikhumbi-ngwenya isivele inomsebenzi wokuphuma emanzini ukuze iskene ngokushesha isonto lonke, bese ikhombisa umsebenzi wokubheka ngemva kokuhoxisa. Imikhumbi engaphezulu ingasebenzisa ukutholwa kwe-infrared kanye nesistimu yokulandelela ukuqapha ukuhlasela kwezindiza zezitha nemikhumbi. Ekuqaleni kwawo-1980, iningi labo lalisebenzisa amasistimu okuthola umthombo wamaphuzu. Ibanga lokuhlonza indiza ngqo lalingamakhilomitha angama-20, futhi ibanga lokuya emsileni lalingaba amakhilomitha ayi-100; ibanga lokubuka imicibisholo yamasu esebenzayo lalilikhulu kunamakhilomitha ayi-1,000.
Izinyathelo zokulwa ne-infrared
Ukusetshenziswa kobuchwepheshe be-infrared countermeasure kunganciphisa kakhulu ukusebenza kwesistimu yokuhlonza isitha sombangi kanye nokuhlonza, noma kuyenze ingasebenzi. Izinyathelo zokulwa zingahlukaniswa zibe izigaba ezimbili: ukugwema nokukhohlisa. Ukweqa ukusetshenziswa kwempahla yokufihla ukuze kufihlwe izindawo zempi, izikhali kanye nemishini, ukuze elinye iqembu lingakwazi ukubona umthombo walo we-infrared radiation.
