I-Photon ye-Photon ye-Photon Ichoas

I-photon enyeI-Ingaas Poldetector

Ngophuhliso olukhawulezileyo lweLidar, iUkukhangela ukukhanyaItekhnoloji kunye neTekhnoloji yokuThengisela isetyenziselwe ukulandelela itekhnoloji yokujonga indlela ezizenzekelayo ikwanazo iimfuno eziphezulu, ubuntununtunu kunye nokusonjululwa kwexesha kunye neteknoloji esetyenziswayo kwitekhnoloji yokufumana ukukhanya kwemveli esetyenzisiweyo. I-photon enye yeli yunithi yamandla amancinci, kunye nomhlolisisi onokufunyanwa kwe-phongela enye sisixhobo sokugqibela sokufunyanwa kokukhanya okuphantsi. Xa kuthelekiswa ne-chaasI-APD yefoto, i-photon engatshatanga esekwe kwi-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-APD ye-APD inesantya esiphezulu sempendulo, ubuntununtunu kunye nokusebenza kakuhle. Ke ngoko, uthotho lweephatho luphawu kwi-intanethi ye-gaas APDETECETECTECETYCTECTCETYCTECTATCE KUNYE NOKWENZIWA KWAKHONA KWAKHONA KUNYE NOKHUSELEKILEYO.

Abaphandi baseDyunivesithi yaseMilan e-Itali baphuhlise imodeli emibini yokulinganisa indlela yokulinganisa i-photon enyeI-Avalanche PempletetectNgo-1997, kwaye wanika iziphumo zamanani eempawu zentsusa ze-photon avalanche enye ye-photon avalanche. Ke ngo-2006, abaphandi basebenzise i-mocvd ukulungiselela i-gemetric yejometriI-Ingaas APD yefotoI-Photon yoTangela, eyandisa impumelelo yokufumana i-Photon ye-Photon enye ukuya kwi-10% ngokunciphisa i-faint ebonakalayo kunye nokuphucula umhlaba wombane kwi-heterogeneold inxibelelaniso. Ngo-2014, ngokuphucula ngakumbi iimeko ze-zinc yokungafani komhlaba kunye nokwenza ubume be-veral, i-Photon-Chictockictocking ye-Photon enye inomsebenzi ophakamileyo, ukuya kuthi ga kwi-30%, kwaye iphumelele i-jitter ye-87 Ps. Ngo-2016, sazaro m et al. Ukuhlanganiswa kwe-I-I-I-I-I-APD ye-APD-Photon-i-Photon yemodyuli yemodyuli esekwe kwi-Avalanche Pitter, kwaye inciphisa i-rossech ye-hyble eyona ne-hitter kwi-70 ps. Kwangelo xesha, amanye amaqela ophando aqhube nokwenza uphando kwi-i-chazaas APDifotoI-Photon enye i-photon. Umzekelo, iPrinceton Shatswave yenze i-iaas / i-inpapd i-Photon yoctoctockictor ye-Geton kwaye isebenzise ishishini. IZiko leShanghai leProgics yobugcisa livavanye intsebenzo ye-PET ye-APD isebenzisa ukususwa kweedipozithi ze-zinc kunye nemo yesango lesango le-Gulse eDityani ye-3.6 MHZ. UJoseph p al. Yile i-MESA ye-MESA ye-Imesa Appedetectectectectote yomgcini we-photon ye-photon ye-photon windergap, kwaye isebenzise i-incaasp njengezixhobo ezinobunzima bokufumana impumelelo.

Imodi yokusebenza ye-Insaas Appetectectectecttor I-Photon Recictor Imowudi yokuSebenza yasimahla yiyoKhetha isiphaluka se-peipheral emva kokuba u-Avalanche wenzeka kangangexesha elithile. Ukwenzela ukunciphisa ifuthe lokucima ixesha lokulibaziseka, kuluhlu olucwangcisiweyo lokusebenzisa isiphaluka esisebenzayo se-ROW NOKUFUNDA NGOKUFANELEKILEYO NGOKUFANELEKILEYO KWI-POFE YENDLELA YOKUGQIBELA OKANYE YENZA ISIQINISEKISO SE-PATE KWI-GALD OKANYE YENKONZO YAMANQAKU APHAKATHI OKUFANELEKILEYO, UKUQHUTYELWA NGOKUGQIBELA NGOKUGQIBELA Ingxaki yeposi engafakwanga ngaphambili. Ngapha koko, ukufunyanwa kwempumelelo kwi-1550 NM yi-10%, kwaye amathuba okutsala emva kwepulse ancitshiswa abe ngaphantsi kwe-1%. Okwesibini kukuqonda ukucofa ngokukhawuleza nokuvuselela ngokulawula inqanaba le-bias voltage. Kuba ayixhomekekanga kulawulo lwengxelo ye-Avalanche Pulse, ixesha lokulibazisa ukuncitshiswa lincitshisiwe kwaye ukufumanisa ukusebenza kwempumelelo komfundi kuphuculwe. Umzekelo, i-LC cocandar et al sebenzisa imowudi ye-GARED. I-git-piton ye-Photon-photon esekwe kwi-I-Ingaas / i-inpapd ilungisiwe. Impumelelo yokufumana i-Photon enye yayingaphezulu kwe-55% nge-1550 NM, kwaye amathuba okutsala emva kwe-7% afezekisiwe. Kule nto, iYunivesithi yeSayensi kunye neTekhnoloji ye-China icwangcise inkqubo ye-idar isebenzisa i-fiber ye-fiber ye-fiber ngaxeshanye i-pied-pied-pitdedee-pitdede-photctor. Isixhobo sovavanyo siboniswe kwi-10 (c) kunye (d), kunye nokufunyanwa kwamafu amaninzi e-12 km kufana nesigqibo se-14 m.
