Optical Fingerprint sensors
Optical fingerprint imaging inosanganisira kutora mufananidzo wedhijitari weyakadhindwa uchishandisa mwenje unooneka. Iyi mhando ye sensor, muchidimbu, inyanzvi yedhijitari kamera. Iyo yepamusoro ye sensor, panoiswa chigunwe, inozivikanwa seyekubata kumeso. Pazasi peiyi layer pane light-emitting phosphor layer inovhenekera pamusoro pemunwe. Chiedza chinoratidzwa kubva pamunwe chinopfuura nepakati pefosphor layer kusvika kune array of solid state pixels (chaji-yakabatana mudziyo) inotora mufananidzo unooneka wemunwe. Iyo yakakwenya kana yakasviba yekubata kumeso inogona kukonzera yakashata mufananidzo wemunwe. Kukanganisa kwerudzi urwu rwe sensor inyaya yekuti kugona kwekufungidzira kunokanganisa nekunaka kweganda pamunwe. Semuenzaniso, chigunwe chakasviba kana chine chiratidzo chakaoma kuita mufananidzo nemazvo. Zvakare, zvinokwanisika kuti munhu abvise chikamu chekunze cheganda paminwe kusvika pasisina chigunwe. Inogona zvakare kunyengedzwa nyore nemufananidzo wemunwe kana usina kubatanidzwa ne "live chigunwe" detector. Nekudaro, kusiyana necapacitive sensors, iyi sensor tekinoroji haikonzereki nekukuvara kwe electrostatic discharge.
