U-Osram wethula i-infrared LED "ubuchwepheshe obumnyama" ukusiza amawashi ahlakaniphile ukuthola ukubonwa kobuso

Muva nje, i-OSRAM yethule imikhiqizo yayo emincane kakhulu ye-infrared LED (IRED) biometric SFH4170S ne-SFH4180S. Ama-IRED amabili amasha anikezela ngosayizi omncane namandla, esiza abenzi bamadivayisi eselula ukuxazulula ukwetheneka kwedatha nezinkinga zokuphepha futhi bahlinzeka ngemcabango owengeziwe womklamo womkhiqizo.

Njengoba abantu bethembela kakhulu kwimikhiqizo yedijithali eselula enjengama-smartphones kanye namawashi angama-smart, ubumfihlo bemfihlo yomuntu siqu nedatha ebucayi buba baluleke kakhulu. Kuvele izindlela ezahlukahlukene zokuvikela ezisuselwa kubiyometric ukunikeza abasebenzisi "ukhiye" oqinile wokuvikela ekufinyeleleni okungagunyaziwe. Kwabakhiqizi bedivayisi yeselula, hhayi kuphela ukubukwa kwezobuchwepheshe kokuphepha, kodwa futhi nosayizi wezinto ezibalulekile badlala indima ebalulekile ekwakhiweni komkhiqizo.

Uma kuqhathaniswa nama-smartphones wesikrini esikhulu, amawashi ahlakaniphile adinga ukusebenzisa imisebenzi ehlakaniphile ehlukahlukene ngevolumu encane. Iphakethe le-Osram P1616 elenziwe ngokwenziwe ngu-Osram lilinganisa kuphela i-1,6mm x 1.6mm x 0.85mm, okwenza i-SFH4170S ne-SFH4180S izakhi ezincane kakhulu ezinhlelweni ze-biometric ze-OSRAM. Lawa ma-IRED amabili asindisa u-50% wesikhala sokuqamba ngokuqhathaniswa nemikhiqizo efanayo emakethe namuhla.

Ngaphandle kosayizi omncane, le mikhiqizo emibili ye-IRED inamandla anamandla we-1150mW njengamanje kwe-1A namandla aqhakaza we-280mW / sr, okubaluleke kakhulu ukuqashelwa kobuso be-2D. Ukuqashelwa kobuso be-2D kuqhathanisa futhi kukhombe izithombe ezigcinwe kusistimu ngokuskena izici zezinhlangothi ezimbili zobuso bomsebenzisi, ezinjengobude bebhulo lempumulo, ubude beso, ubude bomlomo, nokunye. Ukuze kukhonjwe ngokuthembekile izici ezicashile, amakhamera we-infrared kumele akwazi ukuthwebula izithombe ezinhle kakhulu, ngakho-ke ukusetshenziswa kwemithombo enamandla amakhulu kukhanyisa ubuso ngokulinganayo kubalulekile, futhi lokhu kungukuqina okuyimikhiqizo kwemikhiqizo ye-IRED ye-OSRAM.

Ngokwesimo sokugcina se-IRED, amakhasimende angakwazi ukukhetha phakathi kwe-850nm (SFH4170S) noma i-940nm (SFH4180S). Kububanzi be-wavelength be-SFH4170S, inzwa yesithombe inokuzwela okuphezulu, kuyilapho i-SFH4180S ingavikela umphumela "wokuvezwa obomvu" obonakalayo esweni lomuntu, okubuye kube yisidingo esijwayelekile kuzinhlelo zokusebenza zikagesi zabathengi.

U-ArneFleißner, Umphathi Womkhiqizo kuma-Opto Semiconductors e-OSRAM wachaza: “Ama-biometric azoba yingxenye ebaluleke kakhulu yempilo yethu esizayo. Imikhiqizo emibili emisha ye-IRED esiyisusayo izoguqulwa futhi ihlanganiswe kwizikhungo zamakhasimende ethu, hhayi ephephile kuphela, Siyaziqhenya kakhulu ngokuthembekile, ukonga isikhala esengeziwe nokusiza ukuvikela idatha ebucayi yabasebenzisi. "

Ama-SFH4170S kanye ne-SFH4180S afakwe ku-Oslon P1616 futhi angimikhiqizo emincane kakhulu ye-biometric etholakala kwa-OSRAM, ikakhulukazi ukuqashelwa kobuso.

I-OSRAM ye-infrared entsha ye-Ultra-compact isiza iwashi elihlakaniphile liqaphela "ubuchwepheshe obumnyama" bokuqashelwa ubuso.
