Cilmi-baarayaal ka socda Cisco Awoodda isticmaalka daabacayaasha 3D si ay u abuuraan sawir-gacmeedyo faraha oo loo isticmaali karo in lagu khiyaaneeyo hababka xaqiijinta biometric ee loo isticmaalo taleefannada casriga ah, laptop-yada, furayaasha USB iyo qufulyada elektarooniga ah ee warshado kala duwan. Hababka been abuurka ah ee la sameeyay ayaa lagu tijaabiyay noocyo kala duwan oo ah dareemayaasha faraha - capacitive, optical iyo ultrasonic.
Daraasadu waxay muujisay in isticmaalka nashqadaha faraha ee nuqul ka dhigaya faraha dhibbanaha ay ogolaato in telefoonada casriga ah la furo celcelis ahaan 80% isku dayada. Si aad u abuurto clone of faraha, waxaad samayn kartaa la'aanteed
iyada oo aan lahayn qalab gaar ah oo loo heli karo oo keliya adeegyada gaarka ah, iyadoo la adeegsanayo daabacaha 3D ee caadiga ah. Natiijo ahaan, xaqiijinta faraha ayaa loo arkaa inay ku filan tahay ilaalinta taleefanka casriga ah haddii ay dhacdo in la lumiyo ama la xado aaladda, laakiin ma shaqaynayso marka la fulinayo weerarrada la beegsanayo oo uu weeraryahanku go'aamin karo sawirka faraha dhibbanaha (tusaale, isagoo helaya a galaas oo faraha laga qaaday).
Saddex farsamo oo lagu digitiyaynayo faraha dhibbanaha ayaa la tijaabiyay:
- Samaynta kabka balaastiga. Tusaale ahaan, marka dhibbanaha la qabto, miyir daboolan ama sakhraansan.
- Falanqaynta sawirka ku dul hadhay dhalo ama dhalada. Weerarku wuu raaci karaa dhibbanaha oo isticmaali karaa shayga la taabtay (ay ku jirto soo celinta sawirka buuxa ee qaybo).
- Abuuritaanka qaabayn ku salaysan xogta laga helay dareemayaasha faraha. Tusaale ahaan, xogta waxaa lagu heli karaa iyadoo la daadiyo xogta macluumaadka ee shirkadaha amniga ama kastamyada.
Falanqaynta daabacaadda muraayadda waxaa lagu sameeyay iyada oo la abuuray sawir heer sare ah oo qaabka RAW ah, kaas oo filtarrada lagu dabaqay si loo kordhiyo isbarbardhigga iyo ballaarinta meelaha wareegsan ee diyaarad. Habka ku salaysan xogta laga helay dareeraha faraha ayaa u soo baxay inuu noqdo mid waxtar yar, maadaama xallinta ay bixiso dareemaha aysan ku filneyn oo ay lagama maarmaan tahay in la buuxiyo faahfaahinta sawirro dhowr ah. Hufnaanta habka ku salaysan falanqaynta daabacaadda muraayadda (buluug ee garaafka hoose) ayaa isku mid ah ama xitaa ka sarreeya isticmaalka toosan (orange).
Qalabka ugu adkeysi badan ayaa ahaa Samsung A70, HP Pavilion x360 iyo Lenovo Yoga, kuwaas oo si buuxda u awooday inay u adkeystaan ββweerarka iyagoo isticmaalaya far been abuur ah. Samsung note 9, Honor 7x, Aicase padlock, iPhone 8 iyo MacbookPro, kuwaas oo lagu weeraray 95% isku dayo, waxay noqdeen kuwo iska caabbin yar.
Si loo diyaariyo qaab saddex-cabbir ah oo loogu talagalay daabacaadda daabacaadda 3D, xirmo ayaa la isticmaalay . Sawirka daabacaadda waxaa loo adeegsaday burush alfa madow iyo caddaan ah, kaas oo loo adeegsaday in lagu sii daayo daabacaadda 3D. Qaabka la sameeyay waxaa loo adeegsaday in lagu abuuro foom lagu daabici karo iyadoo la adeegsanayo daabacaadda 25D ee caadiga ah oo leh xallinta 50 ama 0.025 microns (0.05 iyo 50 mm). Dhibaatooyinka ugu weyn ayaa ka dhashay xisaabinta cabbirka qaabka, taas oo ah inay si sax ah u dhigma xajmiga farta. Intii lagu guda jiray tijaabooyinka, ilaa XNUMX banaan ayaa la diiday ilaa hab lagu xisaabiyo cabbirka loo baahan yahay.
Marka xigta, iyada oo la adeegsanayo foom daabacan, majaajilo farta ayaa lagu shubay, taas oo loo adeegsaday walxo balaastig ah oo aan ku habboonayn daabacaadda tooska ah ee 3D. Cilmi-baadhayaashu waxay sameeyeen tijaabooyin tiro badan oo kala duwan, kuwaas oo silikoon iyo dhejisyada duntu ay noqdeen kuwa ugu waxtarka badan. Si loo kordhiyo waxtarka la shaqeynta dareemayaasha awoodda leh, graphite conductive ama budada aluminium ayaa lagu daray xabagta.
