Isicelo
Izinkambu zohlelo lokusebenza zochungechunge lwe-R-QCD300 lwe-silicon free-running single-photon detectors zifaka: i-single-photon lidar, i-fluorescence lifetime detection, i-single-photon imaging, i-quantum communication, i-quantum optics, i-optical time-domain reflection, njll. Izinhlelo zokusebenza ezijwayelekile ziboniswe esithombeni esilandelayo.
Isibalo 1 Umdwebo wesimiso wezimo ezijwayelekile zokusetshenziswa komkhiqizo
Ezinhlelweni ezifana ne-single-photon lidar kanye ne-single-photon imaging, umsebe we-laser oshukunyiswayo ukhishwa kusuka ku-laser uye ekuqondisweni. Ama-photon esignali ayahlakazeka noma abonakale lapho ehlangana nama-molecule emoyeni noma ezinhlosweni eziqinile. Ngemva kokuqoqwa endaweni yokukhishwa kwe-laser, kuqoqwa amasignali e-echo photon ahlakazekile noma asakazekile. Lawa masignali atholakala kusetshenziswa ama-detector e-single-photon, futhi amasignali okuthola ahlaziywa kanye namasignali okukhishwa kwe-laser kusetshenziswa ama-converter edijithali yesikhathi ukuthola isikhathi sokundiza kwe-photon. Okokugcina, ibanga lento ekuqondisiwe libalwa kusetshenziswa isivinini sokukhanya. Ezinhlelweni ze-atmospheric lidar, i-laser ehlakazekile evela emkhathini itholakala ukuze kutholakale ulwazi oluphathekayo lomkhathi. Ezinhlelweni ze-third-dimensional imaging lidar, ulwazi lwebanga le-pixel ngayinye lutholakala ngokuskena, bese isithombe esinezinhlangothi ezintathu se-target etholiwe sakhiwa kabusha ngokunembile kusetshenziswa ama-algorithms okuthola. Ngenxa yobudlelwano besikwele obuphambene phakathi kwamandla esignali ye-echo etholwe yi-lidar kanye nebanga lokuthola, njengoba ibanga lokuthola likhula, amandla esignali azoncipha kakhulu. Ngaphezu kwalokho, ngenxa yokuthi i-laser ihlakazekile futhi imuncwa umoya ngesikhathi sokuya nokubuya, amandla esignali azoncipha kakhulu. Uma kuqhathaniswa ne-photoelectric detectors yendabuko, i-single-photon detectors inokuzwela okuphezulu futhi ingasabela kuzimpawu ze-photon ngazinye, okuvumela ukutholwa kwebanga elide futhi kunciphise ukuncika emandleni okukhishwa kwe-laser.
