A photodetector chishandiso chinoshandura zviratidzo zvemazwi mumagetsi emagetsi. Mune semiconductor Photodetector, iyo foto-yakagadzirwa yekutakura inofadza neCocient Photon inopinda mudunhu rekunze pasi peiyo yakasarudzika bastage uye inoumba iyo yekuyera photoscurent. Kunyangwe pakupindura kwakanyanya, pin fo photofananidzo inogona kungogadzira maviri maviri elekroni-gomba mbichana zvakanyanya, icho chishandiso chisina kuwana kwemukati. Kuti uwane hurukuro huru, a avancy photodiode (APD) inogona kushandiswa.
Iyo yekumusoro mhedzisiro ye APD pane PhotoCurrrent inoenderana neIonization collision mhedzisiro. Pasi pemamwe mamiriro, magetsi akakwirisa uye maburi anogona kuwana simba rakakwana kuti awirirane nedombo rekugadzira maviri emagetsi emagetsi. Maitiro aya chiratidzo, zvekuti vaviri vemagetsi emagetsi maeksofa anogadzirwa nekunyorwa kwechiedza anogona kuburitsa huwandu hukuru hwemagetsi-gomba uye gadzira hombe yechipiri foto. Naizvozvo, APD ine hurukuro yakanyanya uye kuwana kwemukati, iyo inovandudza chiratidzo-kune-ruzha ratio yemushini. APD inonyanya kushandiswa mukureba-kure-kure kana diki yemitambo yekutaurirana yekukurukurirana nezvimwe zvisingakwanisi pane iyo yakagashira simba remagetsi. Parizvino, nyanzvi dzakawanda dzepfungwa dzinosarudzika dzakatarisira zvikuru nezve tarisiro dzeAPD.
Rofea yakazvimirira yakagadzirwa Photodetector Photodes Mutsara wechigadzirwa uripo unosanganisira: Analog chiratidzo Photodetector neyemupikicha, GADZIRA ISANGANO YEMAHARA, STEE STEETECECTE (APD), Balancector Cetector, etc.
