Soo Bandhigida Muraayadaha Dahaarka leh: Kobcinta Guryaha Aragga ee Baahiyaha Gaarka ah
Muraayadaha dahaarka leh, oo sidoo kale loo yaqaanno muraayadda milicsiga, waa yaab tignoolajiyadeed heer-gooyo ah oo wax ka beddeleysa sifooyinka muraayadda si ay u buuxiso shuruudaha kala duwan.Adiga oo dabaqaya hal ama dhowr lakab oo bir ah, daawaha, ama filimada isku dhafan ee biraha ah dusha muraayadda, muraayadda dahaarka leh waxay bixisaa faa'iidooyin iyo hawlo kala duwan oo muraayad dhaqameedku weligood gaadhi karin.
Muraayadaha dahaarka leh waxaa loo kala saari karaa qaybo kala duwan iyadoo lagu saleynayo sifooyinkeeda gaarka ah.Muraayadaha dahaarka leh ee kantaroolka qoraxda, dhalooyinka dahaarka leh ee aan qarsoonayn (badanaa loo yaqaan Low-E galaas), iyo galaasyada filimka korantada ayaa ah kala-soocidda ugu weyn ee la heli karo si loo buuxiyo baahiyo kala duwan.
Muraayadaha dahaarka leh ee kantaroolka qoraxda ayaa bixiya xalka ugu habboon ee lagu maareynayo iftiinka qorraxda ee dhererkoodu u dhaxeeyo 350 iyo 1800nm.Muraayadahan waxaa lagu dahaadhay hal ama in ka badan oo lakabyo khafiif ah oo bir ah sida chromium, titanium, birta aan-ka-baxsan, ama xeryahooda.Dahaarkani ma aha oo kaliya inuu kobciyo bilicda muuqaalka muraayadda laakiin sidoo kale wuxuu hubinayaa gudbinta habboon ee iftiinka muuqda, iyada oo la muujinayo milicsiga sare ee fallaadhaha infrared.Intaa waxaa dheer, muraayadda korantada ee xakamaynta qorraxda waxay si wax ku ool ah u nuugtaa fallaadhaha ultraviolet ee waxyeellada leh, iyagoo hubinaya ilaalinta la xoojiyay.Marka la barbar dhigo muraayadda caadiga ah, isku-dheelitirnaanta hadhka ee xakamaynta qoraxda ee muraayadda dahaarka ah ayaa si weyn loo dhimay, hagaajinta waxqabadkeeda hadhka, iyada oo aan la beddelin isku-xidhka wareejinta kulaylka.Sidaa darteed, waxaa badanaa loo tixraacaa sida muraayadda kuleylka, taas oo ka dhigaysa doorashada la doorbido ee codsiyada naqshadaha kala duwan iyo darbiyada muraayadaha.Noocyada kala duwan ee dahaarka dusha sare ee diyaar u ah kulaylka muraayadaha dahaarka leh waxay bixiyaan midabyo badan sida cawl, cawl qalin, cawl buluug, bunni, dahab, jaalle, buluug, cagaar buluug, dahab saafi ah, guduud, casaan kacay, ama dhexdhexaad ah hadh.
Muraayadaha dahaarka hooseeya, oo sidoo kale loo yaqaanno Low-E galaas, waa qayb kale oo soo jiidasho leh oo bixisa milicsi sare ee fallaadhaha infrared fog, gaar ahaan inta u dhaxaysa mawjadaha dhererka 4.5 ilaa 25pm.Muraayada Low-E waxay ka kooban tahay nidaam filim oo ka kooban lakabyo badan oo lacag ah, naxaas ah, tiin, ama biro kale, ama xeryahooda, oo si khibrad leh loogu dhejiyay dusha muraayadda.Tani waxay keenaysaa gudbinta gaarka ah ee iftiinka muuqda oo ay weheliso milicsiga sare ee fallaadhaha infrared.Guryaha kulaylka ah ee muraayadda Low-E waa kuwo aan la mid ahayn, taas oo ka dhigaysa doorasho aad u fiican albaabbada dhismaha iyo daaqadaha.Adigoo si wax ku ool ah u xakameynaya wareejinta kulaylka, muraayadani kaliya ma kordhineyso waxtarka tamarta laakiin sidoo kale waxay hubisaa jawi raaxo leh oo gudaha ah.
Muraayadaha filimada wax-qabadka ah, qayb kale oo ku dhex jirta muraayadda dahaarka leh, waxay furaysaa adduun suurtagal ah oo loogu talagalay teknoolojiyadda casriga ah.Dhaqdhaqaaqeeda aan caadiga ahayn waxay ka timaadaa lakabyo bir ah oo gaar ah, sida indium tin oxide (ITO), oo si khibrad leh loogu dhejiyay dusha muraayadda.Muraayadaha filimada wax-ku-oolka ah waxay helayaan isticmaalka ballaaran ee aaladaha kala duwan ee elektiroonigga ah, oo ay ku jiraan shaashadda taabashada, muraayadaha LCD, iyo muraayadaha qorraxda, sababtoo ah awoodda ay u leedahay inay fududeyso hufnaanta iyo hufnaanta waxtarka leh.
Gebagebadii, muraayadda dahaarka leh ayaa ah beddelka ciyaarta adduunka ee optoelectronics iyo naqshadaha.Waxay bixisaa guryaha indhaha iyo functionalities lagama maarmaanka u ah codsiyada kala duwan.Laga soo bilaabo kontaroolka qoraxda ee muraayadda dahaarka ah, kulaylka milicsiga leh midabyo kala duwan, muraayadda daboolan oo hooseeya oo leh sifooyin heerkul sare ah, iyo muraayad filim ah oo awood u leh xalal farsamo oo horumarsan, muraayadda daboolan ayaa markhaati u ah hindisaha iyo horumarka aadanaha.Ku darida muraayadaha dahaarka leh ee alaabtaada ama mashaariicdaadu waxay shaki la'aan kor u qaadi doontaa heerka xiga ee heer sare.Ku soo dhawoow mustaqbalka farsamada dhalada.
