Maaddaama caqabadaha deegaanka ee caalamiga ahi ay khatar gelinayaan tayada biyaha, waxaa jira baahi sii kordheysa oo ah xalal kormeer oo hufan. Tiknoolajiyada dareenka sawir-qaadista ayaa u soo ifbaxaya rajo leh waqtiga-dhabta ah iyo agabka qiimaynta tayada biyaha ee saxda ah, oo bixisa dareen sare iyo xulasho deegaan biyood kala duwan.
Mabaadi'da Farsamada Dareenka Photonic
Farsamooyinka dareenka Photonic waxay isticmaalaan isdhexgalka aasaasiga ah ee iftiinka-walaxda, sida gudbinta iyo milicsiga, si loo aqoonsado ka-haysashada ama tilmaamayaasha tayada biyaha ee muhiimka ah sida wadarta adkaha la hakiyay (TSS).
Dareemayaashani waxay isticmaalaan ilaha iftiinka sida LED-yada ama laysarka si ay u iftiimiyaan biyaha, halkaasoo cabbirka iyo ka kooban yahay wasakhdu ay saameeyaan isdhexgalka iftiinka, taasoo keenta isbeddel ku yimaada xoojinta iftiinka ama dhererka hirarka.
Isbeddelladan ayaa markaa la duubaa iyadoo la adeegsanayo habab kala duwan oo lagu ogaanayo, oo ay ku jiraan photodiodes, phototransistor, ama aaladaha charge-ladeds (CCDs), kuwaas oo cabbira xoogga iftiinka ka dib marka lala falgalo wasakhda. Fiilooyinka indhaha ayaa inta badan loo shaqeeyaa si ay iftiinka ugu toosiyaan ugana soo baxaan muunadda biyaha, taas oo u oggolaanaysa in la dareemo fog ama qaybsan.
Marka lagu daro cabbiraadda gudbinta iftiinka iyo milicsiga, qaar ka mid ah dareemayaasha sawir-qaadista ayaa ka faa'iideysta ifafaale muuqaal gaar ah si loo ogaado wasakhowga. Tusaale ahaan, dareemayaasha fluorescence waxay kiciyaan molecules fluorescent ee biyaha iyagoo leh iftiin mawjadaha dhererka gaar ah waxayna cabbiraan xoojinta iftiinka iftiinka, kaas oo lala xiriirin karo uruurinta wasakhowga gaarka ah.
Taa beddelkeeda, dareemayaasha plasmon resonance (SPR) waxay la socdaan kala duwanaanshaha index refractive ee dusha birta ah ee ka dhasha xidhitaanka molecules bartilmaameedka, iyagoo siinaya calaamad bilaash ah iyo hab lagu ogaanayo waqtiga dhabta ah.
Waxaan ku siin karnaa dareemayaasha tayada biyaha leh cabbiro kala duwan oo loogu talagalay xaaladaha kala duwan ee codsiga, sida soo socota
