Ingabe ubuchwepheshe bezimpawu bukhoma bukhoma kwesithwebuli seminwe saphephile ngempela?

Kunezithombe eziningi zeminwe emakethe egqamisa ubuchwepheshe bezinto ezibukhoma bukhoma njengenye yezinto zabo. Abathengi abaningi abawuqondi kahle umehluko phakathi kwalobu buchwepheshe kanye nokwamukelwa kweminwe ejwayelekile.

(1) Isimiso sobuchwepheshe bokubona iminwe ye-semiconductor

Ukuqashelwa kweminwe yeminwe yemithi kususelwa kuma-capacitance phakathi kwama-caples kanye nezigodi zomunwe kanye nezinhlayiya ze-semiconductor ze-semicecritive ukuthola ukuthi yisiphi isikhundla isigodi. Izigodi nezigodi lapha zihambelana nama-prorrusions kanye nokudangala kweminwe yethu.

Imodyuli eyinhloko ye-semicenductor Fingerprition Ukuqashelwa ibizwa ngokuthi inzwa yeminwe ye-capacitive. Inzuzo yayo ukuthi isithombe somunwe esikhiqizwayo sekhwalithi ephezulu futhi ngokuvamile singenakuhlanekezela. Uma isetshenziswa ekuqashelweni kweminwe, inezinga eliphakeme kakhulu futhi alithambekele ekulweni kweminwe.

(2) Isimiso sobuchwepheshe bokubona iminwe ye-Optical Fingerprition

Isimiso esiyisisekelo sibonisa ukukhanya. Ukukhanya kukhanya endaweni yengilazi nge-Fingerprint kucindezelwe kuyo, futhi ukukhanya okubonisiwe kutholakala yi-CCD (i-Convex lens). Ngemuva kokuthi i-Optical fiber idlula engilazini bese icwebezela esigodini, kuboniswa ngokuphelele endaweni ebonakalayo phakathi kwengilazi nomoya. Ukukhanya kuboniswa kwi-CCD, ngenkathi i-fiber optical eqondiswe egunjini ayiboniswa ngokuphelele, kepha imunwe noma iboniswe kwezinye izindawo, ngaleyo ndlela yakha isithombe esicacile ku-CCD.

(3) Ukuqhathanisa phakathi kwamakhanda we-semiconductor namakhanda weminwe

Ngakho-ke, i-Live Fingerprint ephakanyiswe ngumenzi ungobuchwepheshe bokubona umunwe weminwe. Ubuchwepheshe be-Semicondector buvuthiwe futhi kuphephile kakhulu ukuthi kusetshenziswe esikrinini somunwe.

Ukuqashelwa kweminwe ebukhoma ukusebenzisa izici zikagesi zezicubu ze-Derris Human ukuthola idatha yesici somunwe esiqhubekayo nesebenzayo yeminwe yangempela yabantu. Ukuqashelwa kweminwe bukhoma kungangena ku-dermis ungqimba sezicubu zesikhumba somuntu ukuze kuhlonzwa iminwe, kuthuthukisa ukusebenza kahle nokuphepha.
