ROF Si photondetector avalanche photodiodes free running single photon detector
Chinhu
- Kuona fotoni imwe chete: Kukwanisa kuona zviratidzo zvephotoni imwe chete mubhendi rechiedza rinooneka;
- Kutaurirana neUSB: Kunotsigira kutaurirana nekombuta inochengeta data kuburikidza neprotocol yeUSB 2.0, zvichigonesa kurodha pasi ma parameter configuration, status reporting, data upload, uye mamwe mabasa ane chekuita ne debugging;
- Kuvimbika kwakanyanya: Kuchengetedza kugadzikana kwekushanda kwesystem munzvimbo dzakasiyana dzekushanda kuburikidza nemaalgorithms ekusimbisa anoshanda;
- Kugadzirisa kuri nyore: Kunotsigira kutarisa uye kudzora mamiriro ehurongwa panguva chaiyo;
Kushandiswa
Nzvimbo dzekushandisa dzeR-QCD300 series yesilicon free-running single-photon detectors dzinosanganisira: single-photon lidar, fluorescence lifetime detection, single-photon imaging, quantum communication, quantum optics, optical time-domain reflection, nezvimwewo. Mashandisirwo akajairika anoratidzwa mumufananidzo unotevera.
Mufananidzo 1. Dhizaini yemaitiro ekushandisa chigadzirwa
Mumashandisirwo akadai se single-photon lidar uye single-photon imaging, pulsed laser beam inoburitswa kubva ku laser kuenda kune chinangwa. Ma signal photon anopararira kana kuratidza kana asangana nemamorekuru mumhepo kana ma hard targets. Mushure mekuunganidzwa panzvimbo ye laser emission, ma spreadshed kana diffuse reflected echo photon signals anounganidzwa. Ma signals aya anowanikwa achishandisa single-photon detectors, uye ma detection signals anoongororwa pamwe chete nema laser emission signals achishandisa time digital converters kuti awane photon flight time. Pakupedzisira, daro rechinhu chakanangana rinoverengerwa uchishandisa speed yechiedza. Mu atmospheric lidar applications, backscattered laser kubva mumhepo inoonekwa kuti iwane ruzivo rwemuviri rwemhepo. Mu three-dimensional imaging lidar applications, ruzivo rwedaro re pixel yega yega runowanikwa kuburikidza ne scanning, uye ipapo three-dimensional image ye a found target inogadziriswazve nemazvo uchishandisa imaging algorithms. Nekuda kwe inverse square relationship pakati pesimba re echo signal rinogamuchirwa ne lidar ne detection distance, sezvo detection distance ichiwedzera, simba resignal rinoderera zvakanyanya. Uyezve, nekuti laser inopararira uye inonyudzwa nemhepo panguva yerwendo rwayo rwekuenda nekudzoka, simba rechiratidzo richadzikira zvakanyanya. Zvichienzaniswa nezvinoongorora zvemagetsi zvechinyakare, zvinoongorora zvemaphoton rimwe chete zvine hunhu hwakanyanya uye zvinogona kupindura zviratidzo zvemaphoton ega ega, zvichiita kuti zvionekwe kure uye kuderedza kuvimba nesimba rekubudisa laser.
