I-PhotoDesetor yithuluzi eliguqula amasiginali akhanyayo abe amasiginali kagesi. E-semiconductor photonet, isithwali esikhiqizwe isithombe sijabule ngesimo se-Photon singena emjikelezweni wangaphandle ngaphansi kwamandla kagesi asetshenzisiwe futhi akha i-PhotoCopsent engalinganiswa. Noma ekuphenduleni okukhulu, i-PIN Photodiode ingakhiqiza kuphela ama-pair e-elektroni umgodi ngababili, okuyinto divaysi ngaphandle kwenzuzo yangaphakathi. Ukuphendula okukhulu, kungasetshenziswa i-avalanche photodiode (APD).
Umphumela we-Amplification we-APD ku-PhotoCurrent ususelwa emqhumeni wokushayisana kwe-Ionization. Ngaphansi kwemibandela ethile, ama-elektroni asheshayo kanye nezimbobo angathola amandla anele okuhlangana ne-lattice ukukhiqiza amabhangqa asha amasha e-elektroni. Le nqubo ukusabela kwe-chain, ukuze ama-pair of elektroni-umgodi okhiqizwe ngokufakwa kokukhanya kungakhiqiza inani elikhulu lamabili ama-elektroni futhi wakhe i-photocsent yesibili. Ngakho-ke, i-APD inokuphendula okuphezulu kanye nenzuzo yangaphakathi, ethuthukisa isilinganiso se-Signal-to-Noise sedivayisi. I-APD izosetshenziswa ikakhulukazi ezinhlelweni ezide noma ezincanyana zokuxhumana ze-Fiber Optical neminye imikhawulo kumandla we-Optical atholakele. Njengamanje, izingcweti eziningi zedivayisi ebonakalayo zinethemba elikhulu ngamathemba e-APD.
I-ROFEA yathuthukiswa ngokuzimele i-PhotoDode ne-amplifier yomsindo ophansi, ngenkathi ihlinzeka ngemikhiqizo ehlukahlukene, abasebenzisi bocwaningo lwesayensi bahlinzeka ngezinsizakalo zokwenza umkhiqizo osezingeni elifanele, ukwesekwa kwezobuchwepheshe kanye nensizakalo yokuthengisa elula. Umugqa womkhiqizo wamanje ufaka: I-Analog Signal PhotoDETETETET nge-Amplification, Thola i-PhotoDetor eguqukayo, i-PhotoDetor ephezulu ye-PhotoDector, i-APD), umtshina wokulinganisa, njll.
