Chowunikira cha ROF InGaAs Photondector chopanda fotoni imodzi

Chowunikira cha ROF InGaAs Photondector chopanda ntchito chowunikira cha photon imodzi Chithunzi Chodziwika

Kufotokozera Kwachidule:

Chogulitsachi ndi chowunikira chaching'ono cha photon chomwe chimagwira ntchito pafupifupi infrared. Chipangizochi chimagwiritsa ntchito InGaAs/lnP yokhala ndi ufulu wodziyimira pawokha waumwini. Poyerekeza ndi zinthu zofanana, APD ili ndi zizindikiro zapamwamba zaukadaulo, kudalirika komanso kuphatikiza, ndipo ingagwiritsidwe ntchito pozindikira kuwala kochepa monga liDAR ndi kuzindikira kwa fluorescence nthawi zonse. Mapulogalamuwa amapereka njira zotsika mtengo.
Chogulitsachi chimagwiritsa ntchito APD yotsutsa kuti chizimitse chiphalaphala mwachangu komanso phokoso lochepa lamagetsi, kuzindikira bwino kwambiri komanso kuwerengera kochepa kwamdima pokonza zamagetsi ndi kapangidwe ka kutentha. Pakati pawo, mphamvu yayikulu yowunikira ya 1550nm single photon ndi > 35%; Pakadali pano, nthawi yothamanga imatha kukhala yotsika ngati 80ps; Kuzindikira bwino. Pa 15%, kuwerengera kochepa kwamdima ndi 500 CPS, ndipo kutsika kochepa kwa pulse ndi 1% @ nthawi yakufa 5 um; Kuwerengera kuchuluka kwa kukhuta mpaka 4MCps @ nthawi yakufa 250ns. Kuphatikiza apo, pazinthu zinazake zogwiritsira ntchito, kuthandizira kutengera, malire owunikira, nthawi yakufa ndi magawo ena a ntchito yosinthira ogwiritsa ntchito kuti alimbikitse kuzindikira bwino, kuchuluka kwa kuchulukitsa ndi zizindikiro zinazake; Ntchito yosinthira digito (TDC) ikhoza kudziwika. Kuti mupeze deta yowerengera nthawi, kuthandizira kuthamanga kwaulere kapena kuyika kwa choyambitsa chakunja. Pali njira ziwiri zogwirira ntchito.
