Photodtector ndi chipangizo chomwe chimatembenuza chizindikiro pamagetsi. Mu semiconductor chithunzi, chonyamula zithunzi chomwe chakhala chikusangalatsidwa ndi Photon chomwe chakhudzidwa ndi chithunzi cha zithunzizi chimalowa muudindo wakunja womwe umagwiritsidwa ntchito ndi magetsi am'madzi a magetsi a magetsi a magetsi. Ngakhale pakumvera kwakukulu, pini ya Photodiode imangotulutsa awiri elekitron-holers ambiri, yomwe ndi chida chopanda phindu lamkati. Kulabadira kwakukulu, a Aconanche Photodide (APD) angagwiritsidwe ntchito.
The Welmufications of APD pa Photoocment imakhazikika pamavuto ogwiritsira ntchito mankhwalawa. Panthawi zina, mabowo othamanga ndi mabowo amatha kupeza mphamvu zokwanira kugundana ndi chitolirocho kuti apange awiri elekitron-bowo. Njirayi ndi mmodzi mwazomwe zimachitika, kuti awiri a elekitron-hole, omwe amapangidwa ndi matope owala amatha kutulutsa zigawo zingapo zamagetsi - bowo Chifukwa chake, acd ali ndi kutaya mtima kwambiri komanso phindu lamkati, lomwe limapangitsa chiwerengero cha chizindikiritso cha chipangizocho. Apd amagwiritsidwa ntchito makamaka mtunda wautali kapena wocheperako zithunzi zamitundu yocheperako yokhala ndi zofooka zina zovomerezeka. Pakadali pano, akatswiri ambiri owoneka bwino amakhulupirira kwambiri za chiyembekezo cha acd.
ROFEA KWAMBIRI POPANDA Photodtector yonyamula zithunzi zotsika kwambiri, ndikupereka zinthu zosiyanasiyana, ogwiritsa ntchito sayansi amapereka chithandizo chamankhwala chopatsa thanzi, thandizo laukadaulo komanso ntchito yabwino pambuyo pogulitsa. Mzere wazogulitsa wapano umaphatikizapo: Analog siginecha
