Chinthu chilichonse chokhala ndi kutentha pamwamba pa ziro kwenikweni chimatulutsa mphamvu mumlengalenga ngati kuwala kwa infrared. Tekinoloje yozindikira yomwe imagwiritsa ntchito ma radiation ya infrared kuyeza kuchuluka kwakuthupi koyenera imatchedwa ukadaulo wa infrared sensing.
Tekinoloje ya infrared sensor ndi imodzi mwamaukadaulo omwe akutukuka kwambiri m'zaka zaposachedwa, sensa ya infrared yakhala ikugwiritsidwa ntchito kwambiri muzamlengalenga, zakuthambo, zakuthambo, zankhondo, zamafakitale ndi zaboma ndi zina, zomwe zimagwira ntchito yofunika kwambiri. Infrared, kwenikweni, ndi mtundu wa mafunde amagetsi amagetsi, kutalika kwake ndi pafupifupi 0.78m ~ 1000m sipekitiramu osiyanasiyana, chifukwa ili mu kuwala kowoneka kunja kwa kuwala kofiyira, komwe kumatchedwa infrared. Chinthu chilichonse chokhala ndi kutentha pamwamba pa ziro kwenikweni chimatulutsa mphamvu mumlengalenga ngati kuwala kwa infrared. Tekinoloje yozindikira yomwe imagwiritsa ntchito ma radiation ya infrared kuyeza kuchuluka kwakuthupi koyenera imatchedwa ukadaulo wa infrared sensing.
Photonic infrared sensor ndi mtundu wa sensor yomwe imagwira ntchito pogwiritsa ntchito mawonekedwe a photon a radiation ya infrared. Zomwe zimatchedwa photon effect zimatanthawuza kuti pamene pali chochitika cha infuraredi pazinthu zina za semiconductor, photon ikuyenda mu infuraredi cheza imalumikizana ndi ma elekitironi muzinthu za semiconductor, kusintha mphamvu ya magetsi, zomwe zimapangitsa kuti pakhale zochitika zosiyanasiyana zamagetsi. Poyesa kusintha kwamagetsi a zida za semiconductor, mutha kudziwa mphamvu ya radiation yofananira ndi infuraredi. Mitundu yayikulu ya ma photon detector ndi mkati mwa photodetector, photodetector kunja, free carrier detector, QWIP quantum well detector ndi zina zotero. Ma photodetectors amkati amagawidwanso mu mtundu wa photoconductive, mtundu wopangira photovolt ndi mtundu wa photomagnetoelectric. Makhalidwe akuluakulu a chojambulira cha photon ndi kukhudzika kwakukulu, kuthamanga kwachangu, ndi kuyankha kwachangu, koma choyipa chake ndi chakuti gulu lodziwikiratu ndilopapatiza, ndipo nthawi zambiri limagwira ntchito pa kutentha kochepa (kuti mukhalebe okhudzidwa kwambiri, nitrogen yamadzimadzi kapena thermoelectric. firiji nthawi zambiri imagwiritsidwa ntchito kuziziritsa chojambulira cha photon ku kutentha kochepa kwambiri).
Chida chowunikira chigawo chozikidwa pa ukadaulo wa infrared spectrum chili ndi mawonekedwe obiriwira, othamanga, osawononga komanso pa intaneti, ndipo ndi imodzi mwamatukuko ofulumira aukadaulo wapamwamba wowunikira pamunda wa chemistry yowunikira. Mamolekyu ambiri a gasi opangidwa ndi ma diatomu asymmetric ndi ma polyatomu ali ndi mayamwidwe ofanana mu gulu la ma radiation a infrared, ndipo kutalika kwa mafunde ndi mphamvu ya mayamwidwe a magulu amayamwidwe ndi osiyana chifukwa cha mamolekyu osiyanasiyana omwe ali muzinthu zoyezedwa. Malinga ndi kugawa magulu mayamwidwe a mamolekyu osiyanasiyana mpweya ndi mphamvu mayamwidwe, zikuchokera ndi zili mpweya mamolekyu mu chinthu kuyeza akhoza kudziwika. Kuwunikira kwa gasi wa infrared kumagwiritsidwa ntchito kuwunikira sing'anga yoyezera ndi kuwala kwa infrared, komanso kutengera mawonekedwe a infrared mayamwidwe amitundu yosiyanasiyana yama cell, pogwiritsa ntchito mawonekedwe a infrared mayamwidwe a gasi, kudzera kusanthula kowoneka bwino kuti akwaniritse kapangidwe ka gasi kapena kusanthula ndende.
The diagnostic sipekitiramu wa hydroxyl, madzi, carbonate, Al-OH, Mg-OH, Fe-OH ndi zina zomangira maselo akhoza analandira ndi infuraredi walitsa wa chandamale chinthu, ndiyeno wavelength udindo, kuya ndi m'lifupi sipekitiramu sipekitiramu akhoza kukhala. kuyeza ndi kusanthula kupeza mitundu yake, zigawo zikuluzikulu ndi chiŵerengero cha zinthu zazikulu zitsulo. Chifukwa chake, kusanthula kwamagulu a media olimba kumatha kuchitika.
