Ndi kukula kwa liddar,Kuzindikira KuwalaTekinoloje ndi ukadaulo wambiri womwe umagwiritsidwa ntchito potsata matekitala othamanga omwe amakhalanso ndi zofunikira kwambiri, kumverera ndi kusintha kwa nthawi yolemba muukadaulo wocheperako sikungakwaniritse zosowa zenizeni. Photon imodzi ndi gawo laling'ono kwambiri la kuwala, ndipo chojambulacho ndi luso lodziwika bwino la Photon ndi chida chomaliza cha kuwonekera kochepa. Poyerekeza ndi inghaasPhotodtectorOfufuza osakwatiwa amatengera ingdaas Apd Photodtector ali ndi njira yothandizira kwambiri, chidwi ndi luso. Chifukwa chake, mndandanda wa ziwonetsero ku-Gaas apd chithunzi

Ofufuzawo ochokera ku yunivesite ya Milan ku Italy adayamba kupanga mtundu wa magawo awiri kuti athetse mayendedwe a Photon imodziChithunzithunzi cha AvalcheMu 1997, ndipo anapatsa zotsatira zowerengeka za mikhalidwe yotsirizira ya Photon Chenrantector. Kenako mu 2006, ofufuzawo adagwiritsa ntchito mocvd kuti akonzekere dongosolo la plankIngaas Apd ChithunziWotchinga ya Photon Shon, yomwe idawonjezera kuzindikirika kwa chithunzi chimodzi mpaka 10% pochepetsa mawonekedwewo ndikuwonjezera gawo lamagetsi pamawonekedwe a mawonekedwe a herurogeneous. Mu 2014, pokonzanso mawonekedwe a zinc ndikutha kukonza mawonekedwe, chojambulira cha zithunzi chimodzi chimakhala chokwanira chokwanira, mpaka 30%, ndikukwaniritsa nthawi pafupifupi 87 Sal. Mu 2016, Sanzaro M et al. Wophatikizidwa ndi Ingaas Apd Phondodetector Onts-Photon Countraser wophatikizidwa, ndikupanga njira yokhazikika yokhazikika yomwe imachepetsa post Nthawi yomweyo, magulu ena ofufuza achitanso kafukufuku pa ingd acdchithunzichotchinjiriza ku Photon. Mwachitsanzo, Princeton Drightwave wakonza mutu wa ISAS / Inpapd Shamen Photon ndi mawonekedwe a mitengo ndikuyika mu malonda. The Shanghai Institute of Travics idayesa magwiridwe a Photon amodzi a APD Photodtector pogwiritsa ntchito chipata cha zitsamba ndi mawonekedwe a chipata choyenera cha 1.6 mhz. Joseph p et al. Anapanga kupanga mesas Spais Apd Phondodetor Shoedon Steoton Shopen Photon Shot Center

Njira yogwiritsira ntchito ya Ingas Apd Photodetoct Stevetor Stopector ndi njira zaulere, ndiye kuti, chithunzi cha apd chikufunika kufinya nthawi yayitali. Pofuna kuchepetsa mphamvu yochepetsera, imagawika mitundu iwiri: imodzi ndikugwiritsa ntchito gawo lokhazikika la ma ench erget ndi cholumikizira cha Apd Njira yoyendetsera, kuchepetsa kwambiri vuto lomwe linali losatheka kale. Kuphatikiza apo, kupezeka kwa madokotala pa 1550 nm ndi 10%, ndipo kuthekera kwa kukoka kwa pambuyo pake kumachepetsedwa mpaka 1%. Lachiwiri ndikuzindikira msanga ndikuchira pakuwongolera kuchuluka kwa magetsi am'madzi. Popeza sizitengera kuwongolera mayankho a kuvarako, nthawi yopuma imachepetsedwa kwambiri ndipo kupezeka kwa chizindikiritso cha chofufumitsa kumayendetsedwa. Mwachitsanzo, LC Comandar et al amagwiritsa ntchito mawonekedwe am'mimba. Chojambulira cha Photon-Photon-Photon chotsatira pa inghaas / inpoapd adakonzedwa. Kuzindikira kwa zithunzi chimodzi chimodzi kunali kupitirira 55% pa 1550 nm, ndipo kuthekera kwa post-kuchitika kwa 7% kunatheka. Pamaziko awa, yunivesite ya China ndi ukadaulo wa China idakhazikitsidwa kachitidwe kazinthu zingapo zomwe zimaphatikizidwa ndi sutaas apd chithunzi chotchinga chimodzi. Chida choyesera chikuwonetsedwa chithunzi (c) ndi (d), ndipo kupezeka kwa mitambo yothitsika ndi 12 km kumadziwika ndi nthawi ya 15 m.
