Mbali
- Kuzindikira fotoni imodzi: Kutha kuzindikira zizindikiro za fotoni imodzi mu gulu lowala looneka;
- Kulankhulana kwa USB: Kumathandizira kulumikizana ndi kompyuta yolandira kudzera mu protocol ya USB 2.0, zomwe zimathandiza kutsitsa ma parameter configuration, malipoti a momwe zinthu zilili, kukweza deta, ndi ntchito zina zokhudzana ndi kukonza zolakwika;
- Kudalirika Kwambiri: Kumasunga kukhazikika kwa magwiridwe antchito a makina m'malo osiyanasiyana ogwirira ntchito kudzera mu ma algorithms okhazikika;
- Kusamalira kosavuta: Kumathandizira kuyang'anira ndikuwongolera momwe zinthu zilili mu dongosolo nthawi yeniyeni;
Kugwiritsa ntchito
Magawo ogwiritsira ntchito a R-QCD300 series of silicon free-running single-photon detectors akuphatikizapo: single-photon lidar, fluorescence lifetime detection, single-photon imaging, quantum communication, quantum optics, optical time-domain reflection, ndi zina zotero. Magwiritsidwe ntchito wamba akuwonetsedwa pachithunzi chotsatirachi.
Chithunzi 1 Chithunzi cha ndondomeko cha zochitika zomwe zimagwiritsidwa ntchito pa malonda
Mu ntchito monga single-photon lidar ndi single-photon imaging, kuwala kwa laser komwe kumayendetsedwa ndi pulsed kumatuluka kuchokera ku laser kupita ku chandamale. Ma photon a chizindikiro amabalalika kapena kuonekera akakumana ndi mamolekyu mumlengalenga kapena zolinga zolimba. Pambuyo posonkhanitsidwa pamalo otulutsa laser, zizindikiro za echo photon zobalalika kapena zofalikira zimasonkhanitsidwa. Zizindikirozi zimapezeka pogwiritsa ntchito zida zowunikira za single-photon, ndipo zizindikiro zozindikira zimasanthulidwa pamodzi ndi zizindikiro zotulutsa laser pogwiritsa ntchito nthawi ya digito kuti zipeze nthawi yowuluka ya photon. Pomaliza, mtunda wa chinthu chomwe chikufunidwa umawerengedwa pogwiritsa ntchito liwiro la kuwala. Mu ntchito za atmospheric lidar, laser yochokera kumbuyo kuchokera mumlengalenga imapezeka kuti ipeze chidziwitso chakuthupi cha mlengalenga. Mu ntchito za lidar zojambulira za magawo atatu, chidziwitso cha mtunda wa pixel iliyonse chimapezeka kudzera mu scanning, kenako chithunzi cha magawo atatu cha chandamale chomwe chapezeka chimamangidwanso molondola pogwiritsa ntchito ma algorithms ojambulira. Chifukwa cha ubale wapakati pakati pa mphamvu ya chizindikiro cha echo chomwe chimalandiridwa ndi lidar ndi mtunda wozindikira, pamene mtunda wozindikira ukuwonjezeka, mphamvu ya chizindikiro idzachepa kwambiri. Komanso, chifukwa chakuti laser imafalikira ndikulowetsedwa ndi mlengalenga panthawi yobwerera, mphamvu ya chizindikiro imachepa kwambiri. Poyerekeza ndi zida zodziwira zamagetsi zamagetsi, zida zodziwira za photon imodzi zimakhala ndi mphamvu zambiri ndipo zimatha kuyankha zizindikiro za photon payekha, zomwe zimathandiza kuzindikira kutali ndikuchepetsa kudalira mphamvu yotulutsa laser.
