Sawir-qaade waa qalab u beddela calaamadaha iftiinka calaamadaha korontada. Sawir-qaade semiconductor ah, qaade sawir-qaade oo ku faraxsan sawirka dhacdada wuxuu galaa wareegga dibadda iyadoo hoos timaad danab eexda oo la dabaqay oo uu sameeyo sawir la cabbiri karo. Xataa marka ay jawaabta ugu badan tahay, photodiode-ka pin-ku waxa uu soo saari karaa oo kaliya laba lammaane oo dalool elektaroonig ah inta ugu badan, taas oo ah qalab aan faa'iido gudaha ah lahayn. Si loo helo jawaab celin weyn, avalanche photodiode (apd) ayaa la isticmaali karaa.
Saamaynta kordhinta apd ee sawirka hadda jirta waxay ku salaysan tahay saamaynta isku dhaca ionization. Xaaladaha qaarkood, elektaroonnada la dedejiyey iyo godadka waxay heli karaan tamar ku filan si ay ugu dhacaan shabagga si ay u soo saaraan lammaane cusub oo ah godad elektaroonig ah. Habkani waa falcelin silsilad ah, si labada lammaane ee godka elektarooniga ah ee ay dhaliso nuugista iftiinka waxay soo saari karaan tiro badan oo lammaane godad elektaroonig ah waxayna sameeyaan sawir-qaade sare oo weyn. Sidaa darteed, apd waxay leedahay jawaab celin sare iyo faa'iido gudaha ah, taas oo wanaajisa saamiga signal-ilaa-sanqa ee qalabka. apd waxaa inta badan loo isticmaali doonaa fogaan dheer ama hababka isgaarsiinta fiber indhaha ka yar oo leh xaddidaadyo kale oo ku saabsan awoodda indhaha ee la helay. Waqtigan xaadirka ah, khabiiro badan oo aaladaha indhaha ah ayaa aad ugu rajo weyn rajada apd.
Rofea waxay si madax-bannaan u horumarisay sawir-qaade sawir-qaade isku-dhafan oo isku-dhafan iyo wareegga cod-weyneeye hoose, iyadoo la siinayo alaabooyin kala duwan, dadka isticmaala cilmi-baarista cilmi-baarista waxay bixiyaan adeeg wax-ka-beddelid tayo leh, taageero farsamo iyo adeegga iibka kaddib. Khadka wax soo saarka ee hadda jira waxaa ka mid ah: sawir-qaade analoog ah oo leh cod-qaade leh, helitaanka sawir-qaade la hagaajin karo, sawir-qaade xawli sare leh, baaraha suuqa barafka (APD), baaraha dheelitirka, iwm.
