Hamwe niterambere ryihuse rya lidar, theKumenya urumuriIkoranabuhanga hamwe nikoranabuhanga ryakoreshejwe mugukurikirana ibinyabiziga byikora kandi bifite ibisabwa byinshi, sensitivite hamwe nigihe cyo gukemura ikibazo gikoreshwa mu buryo bwikoranabuhanga mu buryo buke bwo gutahura. Foonte imwe nigice gito cyingufu zumucyo, kandi ubwumvikane nubushobozi bwo kumenya photon imwe nigikoresho cya nyuma cyo kumenya urumuri rwinshi. Ugereranije na IngaasAPD Photodetetector, pet-photon imwe ishingiye kuri Ingaas Apd Photodetector ifite umuvuduko mwinshi, kumva no gukora neza. Kubwibyo, urukurikirane rw'ubushakashatsi kuri-Gaas Apd Fopitopdetector inganagu Imwe na Foton yakorewe mu rugo no mu mahanga.
Abashakashatsi baturutse muri kaminuza ya Milan mu Butaliyani ba mbere bateguye icyitegererezo cy'igice kinini cyo kwigana imyitwarire yinzibacyuho ya photon imweAvalanche PhotodetetectorMu 1997, kandi bigatanga imibare yibitekerezo biranga imbibi za photon fotodetetector. Hanyuma mu 2006, abashakashatsi bakoresheje Mocvd kugirango bategure geometrikeIngaas Apd PhotodetetectorTerator imwe ya photon, yongereye uburyo bwa photon imwe kugeza kuri 10% mu kugabanya urwego rugaragaza kandi ugamura amashanyarazi kumugaragaro. Muri 2014, mu rwego rwo kurushaho kuzamura imiterere ya zinc no gutegura imiterere ihagaze, telefone imwe ya photon ifite imikorere yo kumenya hejuru, kugeza 30%, kandi igera kuri jite yigihe kingana na 87 Zab. Muri 2016, Sanzaro m et al. Ihuriro Ingaas Apd Photodetector Ifoto ingana na Monolithic yashyizwemo imenyekanisha ryinshi, kandi bigatanga uburyo bwa lybrid. Muri icyo gihe, andi matsinda yubushakashatsi nabwo yakoze ubushakashatsi kuri Ingaas APDPhotodetetectorTerefone imwe. Kurugero, Princeton Liquave yaremye Ingaas / Inpapd Teractor imwe ya photon yatereranye imiterere ihanangurujwe kandi igayashyira mubucuruzi. Ikigo cya tekiniki cya Shanghai cyagerageje imikorere imwe na photon ya apd Photodetector ya APD ukoresheje uburyo bwo gukuraho Zinc Mode hamwe na 3.6 ⁻⁴ / NS Pulse kuri 35 MHz. Joseph p et al. Imiterere ya Mesa yagenewe Ingaas Apd Photodetector ingana na photon detector hamwe na bandgap ya Wider, kandi ikoreshwa na Imari ikurura ibintu byijimye bitagira ingaruka zo kumenya imikorere.
Uburyo bwo gukora bwa Ingaas Apd Photodetector ingana na photon detector ni uburyo bwo gukoresha kubuntu, ni ukuvuga Photodetetector ya APD igomba kuzimya umuzenguruko wa perifeli nyuma yo kubaho mu gihe runaka. Kugirango ugabanye ingaruka zo gutinda gutinda, bigabanijwemo ubwoko bubiri: imwe nugukoresha umuzenguruko wa pasiporo kugirango ugere kuri elegitoronike, nibindi (B) Uburyo bwo kwiruka kubuntu, kugabanya cyane ikibazo cya nyuma-kidashoboka. Byongeye kandi, guhitamo neza kuri 1550 Nm ni 10%, kandi amahirwe yo gupakira yagabanutse kugera munsi ya 1%. Iya kabiri nukumenya byihuse no gukira mugucunga urwego rwa malotage ya boaga. Kubera ko idashingiye ku kugenzura ibitekerezo bya Avalanche Plise, igihe cyo gutinda cyagabanutse cyane kandi gutahura imikorere ya detector iratera imbere. Kurugero, LC Comondar et Al Koresha uburyo bwamande. Umutegarugori umwe wa photon ushingiye kuri Ingaas / Inpapd yateguwe. Ifishi imwe yo kumenya neza yari hejuru ya 55% kuri 1550 Nm, kandi nyuma ya post-lubéta birashoboka 7% byagezweho. Aha hashingiwe na kaminuza ya siyanse n'ikoranabuhanga mu Bushinwa yashyizeho uburyo bwa Lidar bukoresheje fibre ya byinshi icyarimwe hamwe na iGaas i APD Photodetector imwe-Photodetector. Ibikoresho byubushakashatsi byerekanwe ku gishushanyo (C) na (D), no gutahura ibicu byinshi bifite uburebure bwa km 12 bigerwaho nigihe cyo gukemura 1 na m.
