I-Photon Photon Intaas

I-Photon eyodwaI-Ingaas PhotoDetor

Ngokuthuthuka okusheshayo kwe-lidar, TheUkutholwa KokukhanyaUbuchwepheshe obuphakathi nobuchwepheshe obusetshenziselwa ubuchwepheshe bokulandela ngomkhondo wemoto okuzenzakalelayo nabo banezidingo eziphakeme, ukuzwela nokulungiswa kwesikhathi komtshina osetshenzisiwe kubuchwepheshe bokutholwa kwendabuko kwendabuko akunakuhlangabezana nezidingo zangempela. I-Choton eyodwa iyiyunithi elincane kunazo zonke lokukhanya, kanye nomtshina onamandla okuthola isithombe esisodwa yithuluzi lokugcina lokutholwa okuphansi kokutholwa okuphansi. Qhathanisa ne-IngaasI-PhotoDector ye-APD, Abatholi be-Single-Photon ngokususelwa ku-Ingaas APD PhotoDETETECH banejubane lokuphendula eliphakeme, ukuzwela nokusebenza kahle. Ngakho-ke, uchungechunge locwaningo nge-In-Gaas APD PhotoDECECTER LITON PHOTOR STOTETERS yenziwe ekhaya nakwamanye amazwe.

Abaphenyi abavela e-University of Milan e-Italy baqala ukuthuthukisa imodeli enezici ezimbili ukuze kulingiswe ngokuziphatha kwesikhashana kwe-photon eyodwaI-Avalanche PhotoDepectorNgo-1997, futhi yanikeza imiphumela yokulingisa kwezinombolo yezimpawu zesikhashana ze-Photon Vopton Avalanche PhotoDenet. Kwathi ngo-2006, abacwaningi basebenzisa iMocvd ukulungiselela i-Planar geometricI-Ingaas APD PhotoDepectorUmtshina wesithombe esisodwa, esandisa ukusebenza kahle kokutholwa kwe-Photon-Photon ku-10% ngokunciphisa ungqimba olukhanyayo kanye nokwenza ngcono insimu kagesi esibonakalayo se-heterogeneous. Ngo-2014, ngokuqhubeka nokwenza ngcono izimo ze-zinc ukuguquguquka nokwenza kahle isakhiwo esithe mpo, umtshina we-perton-phon unokusebenza okuphezulu kokutholwa, kuze kufike ku-30%, bese kufinyelela isikhathi sesikhathi esingama-87 ps. Ngo-2016, sanzaro m et al. Kuhlanganiswe umtshina we-Ingaas APD PhotoDETECUCTICE-PHOTOS PHONECRICE APROGICIC OPPROR, COMDICE SOPLEL-PHONLING VOSTING Module ngokusekelwe kwi-Avalanche Candlel, kanye ne-crosstalk ye-apping ne-spitical crosstalk, kanye nokunciphisa isikhathi sesikhathi se-PS ku-70 PS kuya ku-70 PS. Ngasikhathi sinye, amanye amaqembu okucwaninga nawo enza ucwaningo nge-Ingaas APDI-PhotoDETETETETECETETETumtshina owodwa we-photon. Isibonelo, i-Princeton LightWave iye yakha umtshina we-Igaas / ipapd single photon deten ngesakhiwo seplanethi bese uyisebenzisa ngokusetshenziswa kwezentengiso. I-Shanghai Institute of Technical Physics ihlole ukusebenza kwe-Photon-Photon ye-APD PhotoDector isebenzisa ukususwa kwamadiphozithi we-zinc kanye ne-capacitive gate pulse mode ngesibalo esimnyama esingu-3.6 × 10 ⁻⁴ / NS UJoseph P et al. Yakhelwe Isakhiwo seMesa Ingaas APD Photon Photon Deten deten nge-bandgap ebanzi, futhi wasebenzisa i-Ingaapp njengezinto eziphansi zokuthola indawo ephansi ngaphandle kokuthinta ukusebenza kahle okuphansi ngaphandle kokuthinta ukusebenza kahle.

Imodi yokusebenza ye-Ingaas APD PhotoDector Single Photon Detector imodi yokusebenza yamahhala, okungukuthi, i-PhotoDector ye-APD idinga ukuqeda umjikelezo we-peripheral ngemuva kokuthi i-avalanche yenzeke, futhi ilulame ngemuva kokucima isikhathi esithile. Ukuze unciphise umthelela wokuqedwa isikhathi sokulibala, uhlukaniswe ngezinhlobo ezimbili: eyodwa ukusebenzisa umjikelezo oshubile noma osebenzayo wokuqedwa kokulawulwa kwe-acter, (b), i-accounting field, i-app PhotoDetor, eyenzelwe ukusebenza ngemodi yokugijima yamahhala, kakhulu Ukunciphisa inkinga engahleliwe eyayingatholakali ye-post-pulse. Ngaphezu kwalokho, ukusebenza kahle kokutholwa ngo-1550 nm kungu-10%, futhi amathuba okuphapha ancishisiwe ancishiswe abe ngaphansi kwe-1%. Okwesibili ukubona ukuqeda ngokushesha nokululama ngokulawula izinga le-BIAS Voltage. Njengoba kungaxhomekeki ekuphathweni kwempendulo ye-avalanche pulse, isikhathi sokubambezela sokuqedwa sincishiswa kakhulu futhi ukusebenza kahle komtshina kuyathuthukiswa. Isibonelo, i-LC Comandar et al Sebenzisa imodi ye-GAED. Umtshina we-gated owesithombe owodwa osuselwa ku-Ingaas / inPAPD walungiswa. Ukusebenza kokutholwa kwezithombe okukodwa kwe-Photon bekungaphezulu kwama-55% ku-1550 nm, futhi amathuba okuphambuka we-750 atholakala. Ngalesi sisekelo, i-University of Science neTechnology yaseChina yasungula uhlelo lwe-lidar kusetshenziswa i-culy-mode fiber ngasikhathi sinye ngemodi yamahhala ye-Ingaas APD Photo I-APD PhotoDod-Phon Detector eyodwa Imishini yokuhlola iboniswa kuMfanekiso (C) no (D), kanye nokutholwa kwamafu ahlukahlukene anokuphakama okuphezulu kwe-12 km kutholakala ngesinqumo sesikhathi sika-1 s kanye nokuxazululwa kwendawo okungu-15 m.
