A sawir-qaadewaa qalab calaamadaha iftiinka u beddela calaamado koronto.sawir-qaade semiconductor ah, side-ka sawir-qaadaha ee ku faraxsan dhacdada photon-ka ayaa galaya wareegga dibadda iyadoo la adeegsanayo danabka eexda ee la adeegsaday wuxuuna sameeyaa koronto sawireed oo la cabbiri karo. Xitaa marka ay ugu badan tahay jawaab celinta, photodiode-ka biinka ah wuxuu soo saari karaa oo keliya labo lammaane oo godad elektaroonik ah ugu badnaan, kaas oo ah qalab aan lahayn faa'iido gudaha ah. Si loo helo jawaab celin weyn,photodiode-ka barafka(apd) ayaa loo isticmaali karaa.
Saamaynta kordhinta ee apd ee ku saabsan iftiinka sawir-qaadista waxay ku salaysan tahay saameynta isku dhaca ionization. Xaaladaha qaarkood, elektaroonada degdega ah iyo godadka waxay heli karaan tamar ku filan oo ay kula dhacaan shabagga si ay u soo saaraan lammaane cusub oo ah lammaane-god elektaroonik ah. Habkani waa falgal silsilad ah, si labada lammaane ee god-ka elektaroonik ah ee ka dhasha nuugista iftiinka ay u soo saari karaan tiro badan oo lammaane-god elektaroonik ah waxayna samayn karaan sawir-qaadis labaad oo weyn. Sidaa darteed, apd waxay leedahay jawaab celin sare iyo faa'iido gudaha ah, taas oo hagaajinaysa saamiga calaamadda-ilaa-qaylada ee qalabka. apd waxaa inta badan loo isticmaali doonaa nidaamyada isgaarsiinta fiber-ka indhaha ee fog ama kuwa yaryar oo leh xaddidaadyo kale oo ku saabsan awoodda indhaha ee la helay. Waqtigan xaadirka ah, khubaro badan oo qalabka indhaha ah ayaa aad u rajo wanaagsan ka qaba rajada apd.
Rofea si madax-bannaan ayay u horumarisay sawir-qaadaha isku-dhafan ee sawir-qaadaha iyo wareegga cod-qaadaha buuqa yar, iyadoo bixinaysa alaabooyin kala duwan, dadka isticmaala cilmi-baarista sayniska. Waxay bixisaa adeeg tayo leh oo loogu talagalay habaynta badeecada, taageero farsamo iyo adeeg ku habboon iibka kadib. Khadadka wax soo saarka ee hadda jira waxaa ka mid ah: sawir-qaadaha calaamadda analogga ah oo leh kor u qaadis, helitaanka sawir-qaadaha la hagaajin karo,sawir-qaade xawaare sare leh, qalabka lagu ogaado suuqa barafka (APD), qalabka lagu ogaado dheelitirka, iwm.
