Masensa a Optical Fingerprint
Kujambula kwa zala zala kumaphatikizapo kujambula chithunzi cha digito cha chosindikiziracho pogwiritsa ntchito kuwala kowonekera. Sensa yamtundu uwu, kwenikweni, ndi kamera ya digito yapadera. Pamwamba pa sensa, kumene chala chimayikidwa, chimadziwika kuti touch surface. Pansi pa wosanjikiza uwu pali kuwala kotulutsa phosphor komwe kumawunikira pamwamba pa chala. Kuwala komwe kumawonekera kuchokera ku chala kumadutsa pagawo la phosphor kupita kumitundu yambiri ya ma pixel olimba (chipangizo chophatikizana) chomwe chimajambula chithunzi cha chala. Kukhudza konyowa kapena kodetsedwa kungayambitse chithunzi cholakwika cha chala. Choyipa cha mtundu uwu wa sensa ndi chakuti luso lojambula limakhudzidwa ndi khalidwe la khungu pa chala. Mwachitsanzo, chala chodetsedwa kapena chojambulidwa ndizovuta kuchijambula bwino. Komanso, n’zotheka kuti munthu agwetse khungu lakunja kwa nsonga za zala mpaka kufika poti chala sichikuonekanso. Itha kunyengedwanso mosavuta ndi chithunzi cha chala ngati sichinaphatikizidwe ndi chowunikira "chala chamoyo". Komabe, mosiyana ndi masensa a capacitive, ukadaulo wa sensor iyi sungathe kuwonongeka ndi electrostatic discharge.
