Umehluko phakathi kwe-Fingerprint Scanner Optics nama-Semiconductors

Ngokuvuthwa komkhakha we-Fingerprint Scanner kanye nokwenza ngcono izindinganiso zokuphila kwabantu, abathengi abaningi nabaningi bakhetha isithwebuli somunwe lapho behlobisa noma beshintsha izingidi. Kepha abantu abaningi bazoba nombuzo, yini umehluko phakathi kwesithwebuli somunwe we-semitery kanye ne-semiconductor. Le yinkinga yobuchwepheshe obuhle kakhulu, umehluko phakathi kwe-Optics kanye ne-Semiconductors. Okokuqala, ngavele ngathola ukuthi, umdlali wedrama wakudala we-Smart Lock, akakwazi ukukuqonda. Uyini umehluko phakathi kwalokhu okubili?

I-Optical Fingerprition Isikhathi Straition Isikhathi Sokubakhona Optical Fingerprint Imishini yaqala ngo-1971, futhi isimiso saso sibonisa ukukhanya (ftir). Ukukhanya kushaya indawo yengilazi ngeminwe yeminwe, futhi ukukhanya okubonisiwe kutholakala yi-CCD. Ngemuva kokuthi ukukhanya kulungiselelwe ingilazi esigodini, kuboniswa ngokuphelele esibonelweni phakathi kwengilazi kanye nomoya, futhi ukukhanya kuboniswa ku-CCD, ngenkathi ukukhanya kubhekwe ku-Ridge kungenzeki. Kuboniswa ngokuphelele, kepha kudonswa ukuxhumana kwe-Ridge ngengilazi noma kuboniswe ngokusobala kwezinye izindawo, ngaleyo ndlela kwakha isithombe somunwe esicacile ku-CCD.
I-Semicondector Fingerprint Isikhathi Straition Isikhathi Straition Ku- "Flat Plate" ngezinkulungwane zamadivayisi we-semiconductor, iminwe inamathele kuyo bese yakha olunye uhlangothi lwe-capacitor (i-intantance). , ngenxa yokungalingani kwendiza yomunwe, ibanga langempela phakathi kwe-convex point kanye ne-concave point ethinta ipuleti kuhlukile, kuholele ekutheni inani elihlukile le-capcacitance (i-intanethi). Ngokwalesi simiso, idivaysi ifingqa amanani ahlukene aqoqiwe futhi aqede. ukuqoqwa kweminwe.
I-Optical Fingerpring Isikhathi Straition Isikhathi sokusebenzisa ukusabela okubonakalayo ukuze uqaphele ukucabanga kweminwe, ngenkathi i-semiconductor isebenzisa umehluko ngokwamathuba okuthola umcabango wokwenza imidwebo yeminwe. Kunomehluko obalulekile phakathi kwalaba bobabili emgomweni wokucabanga, ongabaza. Ngemuva kwalokho, ehlanganisa izici zesithwebuli somunwe samanje nezimpawu zokucabanga zalokhu okubili, umehluko uyaphuma.
1. I-Semiconductors yesaba iminwe eyomile nemanzi, ngoba ngokuya ngomgomo wokucabanga kwesigaba, uma umehluko ongaba khona phakathi kwawo mncane kakhulu noma ube mncane kakhulu, bese uyokwazi ukwakha isithombe somunwe esicacile, khona-ke ngeke kube kuhle Ubunzima ekuqasheni, njengeminwe eyomile nemanzi kulokhu, noma ngabe isithombe simnyama, noma isithombe sikhanya kakhulu ukuthi singakhonjwa ngokunembile.
2. I-Optics inezidingo eziphakeme zokushisa komunwe. Yize izidingo zokuvikelwa kokuqashelwa kokuqashelwa zingaphezulu, zinezidingo eziphakeme zokushisa komunwe, futhi zesaba ukuguqulwa kweminwe. Lapho iphansi, kungenye yezizathu zokuthi kungani kunzima kakhulu ukuvula.
3. Imikhiqizo ye-Optical akulula ukuxazulula inkinga yeminwe yeminwe eyinsalela, ngenkathi imikhiqizo ye-semiconductor ayinayo iminwe ye-desidal. Kodwa-ke, imikhiqizo eminingi efanelekile isivele yaxazulula le nkinga. Iminwe ye-residial Finger ingaba yinkinga encane kuphela njengamanje, futhi ayinakubhekwa njengenkinga enkulu yokubona. phezulu.
4. Ama-Optics enziwe ngengilazi eqinile, evikelekile futhi eqinile. Noma ngubani oyisebenzisile uyakwazi lokhu. Wonke umuntu uyazi ukuthi imihuzuko emincane nokuthinta ngeke kulimaze umzimba. Njengoba ama-semiconductors anezakhi ze-elekthronikhi, zimbi kakhulu kulokhu, ziyasaba ukuklwebheka, futhi ukumelana kwazo ukumelana akuyona into enhle njengaleyo ye-Optics. Wonke umuntu kulo mhlaba uyazi;
5. I-Semiconductors yesaba ugesi oqinile, kepha abakhohlisayo abakho. Lokhu kuhlobene kakhulu nomgomo wokucabanga. Abaqhubi be-semicondector bakhonjwa ngogesi, futhi i-Optics incike ezithombeni. Ngakho-ke, uma ugesi oqinile unamandla kakhulu, kuzodala ukulimala okuningi ku-semiconductor. Kukhulu, ngenkathi i-Optics ingenayo le nkinga.
