CCD (them nyiaj {{{- Cov cuab yeej sib txuas yog cov duab Sensor raws cov thev naus laus zis thev naus laus zis. Nws cov qauv tsim qauv yog los digally capptiony kho cov duab los ntawm kev hloov pauv pa hluav taws xob thiab kev hloov pauv hloov dua tshiab. Txij li nws cov lus qhia hauv xyoo 1970, CCD thev naus laus zis tau dhau los ua cov duab txuj ci thiab kev lag luam tawm los ntawm nws cov suab nrov uas muaj kev lag luam zoo, thiab cov lus teb zoo heev.
Tus tsim qauv ntawm CCD lub koob yees duab pib nrog kev sib koom ua ke ntawm cov photodiere array. Thaum lub teeb tsom mus rau saum toj CCD nti los ntawm lub lens kho qhov muag, cov xwm txheej) npog cov silicon substrate, txhawb nqa hluav taws xob- lub qhov khub. Lub PN hlws tej peev xwm muaj peev xwm ua tau cov dej num muaj peev xwm nyob rau txhua lub pixel ntes cov photogen siv hluav taws xob, tsim cov pob ntawv luv sib npaug rau lub teeb siv. Tus txheej txheem no ua tiav kev hloov pauv ntawm cov cim hluav taws xob rau hauv cov cim hluav taws xob, ua tiav tau cov khoom siv hluav taws xob ntau tshaj li 70%, ua tiav cov khoom siv tau zoo tshaj 70%, ua kom pom kev zoo ntawm lub teeb tsis muaj zog.
Hloov pauv yog lub Core cov kev hloov pauv hloov tshiab ntawm CCD. Ntsug thiab kab rov tav hloov cov ntawv sau npe yog nyob hauv qab pixel array. Lub moos {-} driven electrode muaj peev xwm hloov chaw ua rau pob ntawv txav mus rau hauv lub hom phiaj ntawm cov peev xwm ntawm cov peev xwm. Tus Regters Regters Hloov chaw them nqi kauj ruam ntawm kab ntawv nyeem ntawm ntug kev tawm mus rau analog - digital converter (ADC). Qhov no "barrel relay" kis hom kev sib kis hom kev zam txim rau cuam tshuam nrog kev cuam tshuam nrog kev cuam tshuam nrog kev cuam tshuam, ua ke}}
Lub teeb liab ua cov teeb meem correlated ob npaug ntawm cov qauv (CDs) ntawm cov zis analog ntsuas kom tshem tawm cov suab nrov dua thiab cov suab nrov. Niaj hnub CCDs siv rau ntawm -}}}} illuminated cov qauv los txhim kho xiav {}} vi} lub teeb teb. Hauv kev siv hluav taws xob ib puag ncig xws li cov chaw taws teeb Aerospace, txias CCDs Siv Thermoelectric txias kom txo qis kev tsaus ntuj tam sim no kom tsawg li 0.01 electrons ib ob.
Los ntawm kev tsim qauv kev pom zoo, CCD cov koob yees duab kom muaj tseeb ntawm Photon Theem los ntawm kev ua haujlwm zoo ntawm cov kev ua haujlwm zoo ntawm cov neeg siv hluav taws xob thiab kho qhov muag. Txawm hais tias muaj kev loj hlob sai ntawm CMOS sensors nyob rau hauv xyoo tsis ntev los no, thiab lawv cov qauv kev tsim txuj ci, thiab lawv cov qauv kev tsim qauv txuas ntxiv rau kev txhim kho cov duab tshiab sensors.
