Misiyano pakati peFinerprint Scanner Optics uye semiconductors

Nekukura kweiyo munwe wechigungano scanner muindasitiri uye kuvandudzwa kwezvekurarama kwevanhu, vazhinji uye vatengi vanosarudza zvigunwe zvigunwe kana vachishongedza kana kuchinja makiyi. Asi vanhu vazhinji vachange vaine mubvunzo, chii musiyano uripo pakati pechigunwe munwesaiti Scanner Optical uye Semiconductor Fingerprint Kuzivikanwa? Iyi inyanzvi yehunyanzvi hunyanzvi, mutsauko uripo pakati pepamhepo uye semiconducductors. Chekutanga pane zvese, ini ndakangoerekana ndaona kuti ini, mutambi wekare mutambi wekukiya kwakaringana, handinzwisise. Ndeupi musiyano uripo pakati pezviviri?

Optical Fingerprint Kuziva Nguva Yekuenda: Optical Fingerprint Kuunganidza Technology ndeyekare uye yakashandiswa zvakanyanya zvigunwe zvigunwe zvekuunganidza tekinoroji yekuunganidza. Optical yemunwe emunwe wekuunganidza zvishandiso zvakatanga muna 1971, uye nheyo yayo ndeyekuratidzira kwechiedza (ftir). Chiedza chinorova girazi pamusoro neminwe neminwe, uye mwenje unoratidzwa unowanikwa neCCD. Mushure mekunge Chiedza chikaridzwa negirazi kuenda kumupata, zvakanyatsoratidzwa zvachose pamhepo pakati pegirazi nemweya, uye chiedza chinoratidzwa kuCCD, nepo mwenje wakanangidzirwa kugwenzi hariitike. Izvo zvakanyatsoratidzwa zvachose, asi zvakanyudzwa nekuonana kwegomba negirazi kana kusarudzika kuratidzwa kune dzimwe nzvimbo, nokudaro kuumba chifananidzo chakajeka chemunwe pane ccd.
Semiconductor Fingerprint Kuziva Nguva Yekuenda: Iyo Kufungidzira Nheyo ndeyekuti: ingave isingakwanisi kana inductive, nhungamiro, chirevo chakafanana. Pane "blate clate" nezviuru zveMicononductor zvishandiso, zvigunwe zvakabatanidzwa nazvo uye kuumba rimwe divi reCapacitor (induction). , nekuda kwekusakwana kwemunwe wechigunwe, chinhambwe chaicho pakati peiyo convex point uye point point inobata ndiro dzakasiyana, zvichikonzera kusiyana kwakasiyana (kurudziro) kukosha. Maererano nheyo iyi, chishandiso chinopfupisa izvo zvakaunganidzwa tsika dzakasiyana uye dzinopedzisa. kuunganidzwa kwemunwe.
Optical Fingerprint Nguva yekunakidzwa kwekupinda ndeyekuita zvekuita zvekufungidzira kuti uzive kufungidzira kweminwe, nepo Semiconductor inoshandisa mutsauko mukugona kufungidzira kweminwe. Pane musiyano wakakosha pakati pezviviri zviri mukufungidzira nheyo, iyo isingafungiri. Zvadaro, kusanganisa hunhu hwechizvino chigunwe chemunwe scanner uye maitiro ekufungidzira evaviri, musiyano unobuda.
1. semesnetsors anotya kuoma uye akanetesa zvigunwe zvekufungidzira kwechivhura, kana musiyano wacho pakati pavo ari mudiki kana zvidiki, hazvizokwanise kuumba mufananidzo wakajeka wemunwe, ipapo kuchave nekuva kukuru Zvinetso mukucherechedzwa, senge zvigunwe zvakaoma uye zvakanyorova mune ino nyaya, kana mufananidzo wakasviba, kana mufananidzo wakanyanyisa kuzivikanwa nenzira chaiyo.
2. Optics ine zvakakwirira zvinodiwa pamunwe tembiricha. Kunyangwe tembiricha yekuona tembiricha haina kukwirira, ivo vane zvido zvepamusoro pane tembiricha yemunwe, uye vanotya zvigunwe zvigunwe. Kana zvikaderera, ndicho chimwe chezvikonzero nei zvichinetsa kuvhura.
3. Zvigadzirwa zveOptical hazvisi nyore kugadzirisa dambudziko reminwe yakasara yeminwe, nepo Semiconductor zvigadzirwa zvisina kujairika zvigunwe zvigunwe. Nekudaro, zvigadzirwa zvakanyanya kukodzera zvakatogadzirisa dambudziko iri. Kusara kweminwe yeminwe kunogona kungova dambudziko diki parizvino, uye haigone kutaridzwa sedambudziko rakakura renyaya. kumusoro.
4. Iyo Optics inogadzirwa negirazi rakashongedzwa, iro rinopfekedza uye rakasimba uye rakasimba. Chero ani zvake akashandisa anoziva izvi. Wese munhu anoziva kuti zvidimbu zvidiki uye zvinobata hazvizokuvadze muviri. Sezvo menecomoctuctors zvinhu zvemagetsi, ivo vanonamira zvishoma mune izvi, vanotya kukanda, uye kupfeka kwavo kupokana hakuna kunaka senge izvo zvezvipupuridzo. Wese munhu wepanyika anoziva pasi rino;
5. Semiconductrs ari kutya magetsi emagetsi, asi vasipo havapo. Izvi zvine hukama zvakanyanya nenheyo yekufungidzira. Semiconductor hacators inozivikanwa nemagetsi, uye optics kuvimba nemifananidzo. Naizvozvo, kana magetsi emagetsi akanyanya kusimba, zvichakonzera kukuvadza kwakanyanya kuSemiconductor. yakakura, nepo optics isina dambudziko iri.
