Isicelo
Iindawo zokusetyenziswa koluhlu lwe-R-QCD300 lwe-silicon free-running single-photon detectors ziquka: i-single-photon lidar, i-fluorescence lifetime detection, i-single-photon imaging, i-quantum communication, i-quantum optics, i-optical time-domain reflection, njl. Usetyenziso oluqhelekileyo luboniswe kumfanekiso olandelayo.
Umfanekiso 1 Umzobo wesicwangciso seemeko eziqhelekileyo zokusetyenziswa kwemveliso
Kwizicelo ezifana ne-single-photon lidar kunye ne-single-photon imaging, umqadi we-laser oshukumayo ukhutshwa kwi-laser ukuya kwithagethi. Ii-photon zesignali ziyasasazeka okanye zibonakale xa zidibana nee-molecules emoyeni okanye kwiithagethi eziqinileyo. Emva kokuba ziqokelelwe kwindawo yokukhupha i-laser, imiqondiso ye-echo photon ebonakalisiweyo esasazekileyo okanye esasazekileyo iyaqokelelwa. Ezi zimpawu zifunyanwa kusetyenziswa ii-detectors ze-single-photon, kwaye imiqondiso yokufumanisa ihlaziywa kunye nemiqondiso yokukhupha i-laser kusetyenziswa ii-time digital converters ukuze kufunyanwe ixesha lokubhabha kwe-photon. Okokugqibela, umgama wento ekujoliswe kuyo ubalwa kusetyenziswa isantya sokukhanya. Kwizicelo ze-atmospheric lidar, i-laser esasazekileyo evela emoyeni ifunyanwa ukuze kufunyanwe ulwazi oluphathekayo lwe-atmospheric. Kwizicelo ze-three-dimensional imaging lidar, ulwazi lomgama lwe-pixel nganye lufunyanwa ngokuskena, kwaye emva koko umfanekiso we-three-dimensional wethagethi efunyenweyo wakhiwa kwakhona ngokuchanekileyo kusetyenziswa ii-algorithms ze-imaging. Ngenxa yobudlelwane besikwere obuchaseneyo phakathi kwamandla esignali ye-echo efunyenwe yi-lidar kunye nomgama wokufumanisa, njengoko umgama wokufumanisa usanda, amandla esignali aya kuba buthathaka kakhulu. Ngaphezu koko, ngenxa yokuba i-laser isasazekile kwaye ifunxwa ngumoya ngexesha lokujika kwayo, amandla esignali aya kuncipha ngakumbi. Xa kuthelekiswa ne-photoelectric detectors zemveli, i-single-photon detectors zinovakalelo oluphezulu kwaye zinokuphendula kwizibonakaliso ze-photon nganye, zivumela ukubonwa komgama omde kwaye zinciphise ukuxhomekeka kumandla okukhupha i-laser.
