Bhalisela imidiya yethu yezenhlalo yokuthumela okusheshayo
I-Direct Time-of-Flight (DTOF) Technology iyindlela entsha yokulinganisa ngokunembile isikhathi sendiza sokukhanya, sisebenzisa isikhathi esihlobene nesikhathi esisodwa se-Photon Photon (TCSPCC). Lobu buchwepheshe buhlanganiswe ezinhlobonhlobo zezicelo, kusukela ekusondeleni kokuzwakala kuma-elekthronikhi abathengi kuya ku-advanced lidar systems ezinhlelweni zezimoto. Emigodini yayo, amasistimu we-DTOF aqukethe izinto ezimbalwa ezibalulekile, ngalinye lidlala indima ebalulekile ekuqinisekiseni izilinganiso zebanga elifanele.
Izakhi ezibalulekile ze-DTOF Systems
Umshayeli we-laser ne-laser
Umshayeli we-laser, ingxenye ebaluleke kakhulu yesifunda sokudlulisela, ukhiqiza amasiginali we-digilital pulse ukulawula ukuphuma kwe-laser nge-mosfet switch. Ama-lasers, ikakhulukaziI-vertical cavity ebusweni ikhipha ama-lasers(Ama-VCSELL), athandwa nge-spectrum yawo emincane, ukuqina kwamandla aphezulu, amakhono okushintsha wokushintshanisa okusheshayo, kanye nokuhlanganiswa kalula. Ngokuya ngohlelo lokusebenza, ama-wavelength angu-850nm noma ama-940nm akhethiwe ukuze alinganise phakathi kweziqongo zokutholwa kweSolar Spectrum kanye nokusebenza kahle kwe-Sensor Quantum.
Ukudlulisa nokwamukela ama-Optics
Ohlangothini lokudlulisela, ilensi elula yokubona noma inhlanganisela yamalensi aqothula kanye nezinto ezihlukile ze-Optical (enza) ziqondisa umugqa we-laser ngaphesheya komkhakha oyifunayo. I-Optiving etholayo, okuhloswe ngayo ukuqoqa ukukhanya ngaphakathi kwenkambu yethagethi yokubuka, zuza ama-lens ngezinombolo eziphansi ze-F kanye nokukhanyisa okuphezulu okuphezulu, eceleni kwezihlungi eziphakeme eziphakeme ukuqeda ukuphazamiseka kokukhanya okuphezulu.
Izinzwa ze-Spad and Sipm
I-Single-Photon Avalanche Diodes (Sgad) kanye ne-Silicon PhotoMultipliers (SIPM) yizinzwa eziyinhloko ezinhlelweni ze-DTOF. Ama-Spads ahlukaniswa amandla abo okuphendula ama-photon person, aqhakambisa i-avalanche yamanje nge-Photon eyodwa nje, okwenza kube yinto elungele izilinganiso eziphezulu zokunemba. Kodwa-ke, usayizi wazo omkhulu we-pixel uma kuqhathaniswa nezinzwa ze-CMOs zendabuko kukhawulela ukulungiswa kwendawo yezinhlelo ze-DTOF.
Isikhathi-kuya-digital (TDC)
Isifunda se-TDC sihumusha amasiginali we-analog kwizimpawu zedijithali ezimele isikhathi, ethwebula umzuzu oqondile ngamunye we-Photon Pulse aqoshwa. Lokhu kunemba kubalulekile ekunqumeni isikhundla sento eqondiwe ngokuya nge-histogram yama-pulses aqoshiwe.
Ukuhlola amapharamitha wokusebenza kwe-DTOF
Uhla lokutholwa kanye nokunemba
Uhla lokutholwa lwe-DTOF System lufinyelela ngokungemthetho ukuthi ama-pulses alo akhanyayo angahamba abuyele enzwaneni, akhonjwe kahle ngomsindo. Ukuze uthole i-elekthronikhi yabathengi, ukugxila kuvame ngaphakathi kobubanzi be-5M, usebenzisa ama-vcsels, ngenkathi izinhlelo zokusebenza zezimoto zingadinga amabanga okuthola ama-100m noma ngaphezulu, adinga ubuchwepheshe obuhlukahlukene njengama-eels nomaI-Fibre Lasers.

Ububanzi obungathandeki
Uhla oluphezulu ngaphandle kokufiphala kuncike ekuvumeni phakathi kwama-pulses akhishwe kanye nokuguquguquka kokushintsha kwe-laser. Isibonelo, ngokunyusa imvamisa ye-1mhz, uhla olungathandeki lungafinyelela ku-150m.
Ukunemba nephutha
Ukunemba ezinhlelweni ze-DTOOF zikhawulelwe ngokwemvelo ngobubanzi be-laser, kuyilapho amaphutha angavela ekuqinisekisweni okuhlukahlukene ezingxenyeni ezithile, kubandakanya nomshayeli we-laser, impendulo ye-TDC, kanye nokunemba kwesizumbu se-TDC. Amasu afana nokusebenzisa isethenjwa angasiza ukunciphisa la maphutha ngokusungula isisekelo sesikhathi nebanga.
Ukumelana nokuphazanyiswa kanye nokuphazamiseka
Izinhlelo ze-DTOF kumele ziphikisane nomsindo wangemuva, ikakhulukazi ezindaweni ezinamandla zokukhanya. Amasu afana nokusebenzisa amaphikseli amaningi we-spad anamazinga ahlukahlukene ahlukahlukene angasiza ukuphatha le nselelo. Ngokwengeziwe, amandla ka-DTOF ukuhlukanisa phakathi kokucabanga okuqondile nokuphindaphindwayo kuthuthukisa ukuqina kwalo ekuphazanyisweni.
Ukulungiswa kwe-Spatial kanye nokusetshenziswa kwamandla
Intuthuko kubuchwepheshe bezinzwa e-Spad, njengokushintshwa kusuka ekukhanyiseni okungaphambili (i-FSI) ezinqubweni zokukhanyisela (BSI) esiseceleni (BSI), zithuthukise kakhulu amazinga okufakwa kwe-Photon kanye nokusebenza kwenzwa. Le nqubekela phambili, ehlanganiswe nesimo esidwetshiwe sezinhlelo ze-DTOF, imiphumela ekusetshenzisweni kwamandla okuphansi okuqhathaniswa nezinhlelo eziqhubekayo ze-wave ezinjenge-ithof.
Ikusasa lobuchwepheshe be-DTOF
Naphezu kwezingqinamba zezobuchwepheshe eziphakeme ezihambisana nobuchwepheshe be-DTOF, izinzuzo zako ngokunemba, ibanga nokusebenza kwamandla okwenza kube ngumuntu othembisayo wezinhlelo zokusebenza ezizayo. Njengobuchwepheshe be-sensor kanye ne-elektroniki umjikelezo we-elektroniki qhubeka nokuvela, amasistimu we-dtoof alungele ukwamukelwa okubanzi, ukushayela okusha kwi-Consumer Electronics, ukuphepha kwezimoto, nangale kwalokho.
