Nekukura nekukurumidza kweLidar, iyoKuwanikwa kwechiedzaTekinoroji uye tekinoroji yegamba inoshandiswa kune otomatiki yemotokari yekutsvaga tekinoroji zvakare nezvinodiwa zvakanyanya, kugadziriswa kwesimbe kwakashandiswa mutsamba yekuwongorora Imwechete Photon ndeye diki-diki simba chikamu chechiedza, uye detector nekukwanisa kwekuona kamwechete kwekutsvaga chishandiso chekupedzisira chekuonekwa kwechiedza chakaderera. Kuenzaniswa ne IngaasAPD PhotosDetector, single-phonence yekuona zvichibva pane ingaas apd Photodetector ine yepamusoro mhinduro yekumhanyisa, kunzwa uye kushanda zvakanaka. Naizvozvo, dzinoteedzana dzekutsvagisa dziri mu-gaas apd photodetector single phonktors dzakaitwa pamba uye kunze kwenyika.
Vatsvagiri kubva kuYunivhesiti yeMilan muItaly yekutanga yakagadzira maviri-emhando yemhando yekutarisa maitiro ezvepasi eimwe phonomAvalanche PhotodetectorMuna 1997, uye akapa mimwe manhamba ekufungidzira maitiro ehunhu hweimwe Photon Avalanche. Zvino muna 2006, vaongorori vakashandisa mocvd kugadzirira chirongwa chejometriIngaas APD PhotosdetectorImwechete Phon Detector, iyo yakawedzera single-phonics yekukwana kusvika 10% nekudzora iyo yekunyepedzera layer uye kuvandudza munda wemagetsi kuchizunguzi interface. Muna 2014, nekuenderera mberi nekuvandudza iyo zinc yakaipa mamiriro ezvinhu uye optimization chimiro, iyo-phonti yekuona ine yakakwira kugona kwekushanda, kusvika pamakumi matatu muzana, uye inowana Jitter yenguva yeMakore 87. Muna 2016, Sanzaro m et al. Yakabatanidzwa iyo Ingaas APD Photos One-Photon Detector Upeser Syporcory Yakanangana naModule, nekukasira Kuverengera Post-Pulsstalk Cropsk, uye kuderedza Cropsstalk. Panguva imwecheteyo, mamwe mapoka ekutsvagisa akaitawo tsvaga pane Ingaas APDPhotomdetectorsingle phonton detictor. Semuenzaniso, princeton Lightwave yakagadzirirwa Ingaas / Inpapd single phon detector nehurongwa hwekugadzirisa uye uise mukushandiswa kwekutengesa. Iyo Shanghai Institute yeTechnical Fiziki Yakaedzwa Muitiro weAPD PhyDEDEDECKE KUSHANDISA ZINC Deposits neCollanced Depositi ye3,6 Joseph p et al. Yakagadzirwa iyo mesa chimiro Inzwaas APDI
Maitiro ekushanda eaya Kuti uderedze kukonzeresa nguva yekudzokorora, inokonzerwa nemhando mbiri: Imwe ndeyekuti ushandise dunhu rekupedza, etces risizvo maitiro, zvakanyanya kuderedza iyo yaimbove isina kusarudzika post-pulse dambudziko. Uyezve, kugona kwekuona pa1550 NM ndeye 10%, uye mukana wePost-purse unoderedzwa kusvika pasi pe1%. Yechipiri ndeyekuziva nekukurumidza quenching uye kupora nekudzora iyo nhanho ye basias voltage. Sezvo isingavimbi neyekupindura kudzora kweAvane pulse, iyo nguva yekudzokororwa yekudzokorora yakaderedzwa zvakanyanya uye kugona kwekuona kwekuteedzera kwakavandudzwa. Semuenzaniso, LC comandar et al shandisa iyo gated mode. A gated single-phonton detector zvichibva pane ingaas / inpaapd yakagadzirirwa. Iyo imwechete-phonti yekuona yekubudirira yaive kupfuura 55% pa1550 NM, uye iyo post-purse mukana we7% yakawanikwa. Pahwaro uhwu, University of Science uye tekinoroji yeChina yakatanga lidar system uchishandisa yakawanda-mode fiber yakaenzana neyemahara-mode aroas apd photodetector singlector single-Photon detetector single. Midziyo yekuyedza inoratidzwa mumufananidzo (c) uye (d), uye kuongororwa kwemakore mazhinji nehurefu hwegumi nenomwe kunoonekwa nekugadziriswa kweiyo 1 s uye spatial resolution yegumi nemashanu.
