sensa

Lingaliro la sensa ya CMOS (complementary metal oxide semiconductor) linkaganiziridwa mu theka lachiwiri la zaka za m'ma 1960, koma chipangizocho sichinagulitsidwe mpaka teknoloji ya microfabrication itasinthika mokwanira m'ma 1990.CCD (charge coupled device) kapena CMOS (complementary metal oxide semiconductor) masensa azithunzi amagwiritsidwa ntchito m'makamera amakono ndi mafoni am'manja.

CCD ndi CMOS onse ndi zida za semiconductor zomwe zimagwira ntchito ngati "maso amagetsi."

Onsewa amagwiritsa ntchito ma photodiode, koma njira zawo zopangira ndi njira zowerengera zikwangwani zimasiyana.Ngakhale luso la CCD linali lodziwika poyamba chifukwa cha kukhudzidwa kwapamwamba ndi khalidwe lachithunzi, masensa a CMOS anayamba kuchulukira ma sensor a CCD pamtundu wotumizira kuyambira 2004.

Kuchuluka kwa data kumathamanga kuposa CCD.
Gulu la ma capacitor mu chojambulira chophatikizana kachipangizo (CCD) chithunzithunzi chimanyamula chaji yamagetsi molingana ndi kuwala kwa pixel.Zomwe zili mkati mwa capacitor zimasamutsidwa kwa mnansi wake kudzera pagawo lowongolera, ndipo capacitor yomaliza pamndandanda imatsitsa mtengo wake mu amplifier.Masensa a CCD amadziwika ndi njira yotumizira deta ya ndowa-brigade.

Chojambulira chowonjezera chachitsulo cha oxide semiconductor (CMOS).

Kumbali inayi, ili ndi photodiode ndi chosinthira cha CMOS transistor pa pixel iliyonse, zomwe zimalola kuti ma pixel azitha kukulitsidwa mosiyana.Zizindikiro za pixel zitha kupezeka mwachindunji komanso motsatizana, mwachangu kwambiri kuposa kachipangizo ka CCD, posintha masinthidwe.Ubwino wina wokhala ndi amplifier pa pixel iliyonse ndikuti umachepetsa phokoso lomwe limatuluka powerenga ma siginecha amagetsi otembenuzidwa kuchokera ku kuwala kosonkhanitsidwa.

Masensa azithunzi a CMOS ndi otsika mtengo kupanga kuposa masensa amtundu wa CCD chifukwa zida zopangira semiconductor zomwe zilipo zitha kugwiritsidwanso ntchito kupanga.Mosiyana ndi masensa a CCD, omwe amagwiritsa ntchito ma analogi amphamvu kwambiri, masensa a CMOS amagwiritsa ntchito makina ang'onoang'ono a digito omwe amadya mphamvu zochepa ndipo, mwachidziwitso, alibe smear (kuzungulira koyera mu chithunzi chowala) ndi kuphuka (kuwonongeka kwa zithunzi zotere. ngati mawanga oyera).Chifukwa ma logic circuitry amatha kuphatikizidwa pa chip panthawi yopanga, masensa a CMOS okhala ndi makina opangira zithunzi pa-chip akupangidwa kuti agwiritse ntchito monga kuzindikira zithunzi ndi masomphenya ochita kupanga, ndi zida zina zomwe zikugwiritsidwa ntchito pano.

Ronghua, ndi wopanga okhazikika pa R&D, makonda, kupanga, kugulitsa ndi ntchito zama module a kamera, ma module a kamera ya USB, magalasi ndi zinthu zina.Ngati mukufuna lemberani, chonde:
