Amakuru - DTOF Sensor: Ihame rikora nibigizengingo.

Iyandikishe ku mbuga nkoranyambaga kubera umwanya wihuse

Ikoranabuhanga ritaziguye - Indege (DTOF) ni uburyo bushya bwo gupima neza igihe cyo gucana, gukoresha igihe kijyanye na Fhoton Kubara Photon (TCSPC). Iri koranabuhanga ni ibintu bitandukanye kubisabwa, uhereye kubyerekeranye na elegitoroniki ya abaguzi kuri sisitemu ya lidar yateye imbere mubikorwa byimodoka. Kuri sisitemu yacyo, sisitemu ya DTOF igizwe nibice byinshi byingenzi, buriwese akina uruhare rukomeye mugupima intera nyazo.

Ibice byingenzi bya sisitemu ya DTOF

Umushoferi wa Laser na Laser

Umushoferi wa laser, igice cyingenzi cyumuzunguruko woherejwe, kibyara ibimenyetso bya digitale kugirango ugenzure ibihumyo bya laser ukoresheje mosfet yahinduye. Laseri, cyane cyaneGuhinduranya imyuka yo gusohora laser. Ukurikije porogaramu, uburebure bwa 850nm cyangwa 940nm byatoranijwe kugirango biringanire hagati yizuba ryinshi ryizuba ryinjira hamwe na sensor quanim imikorere.

Gushiraho no kwakira Optics

Kuruhande rwa transmit, optique yoroshye cyangwa ihuriro ryibintu byo guhuza no guhuza ibitekerezo (ikora) biyobora urumuri rwa laser hejuru yumurima wifuza. Kwakira optics, bigamije gukusanya urumuri murwego rwintego rwo kureba, nyungu kuri lens hamwe na F-Kumurongo ugereranije na FILUMUMUMANG, kumurikagurisha hejuru, kuruhande rwakaruhuru kugirango ukureho kwivanga.

Spad na sipm sensor

Photon Avalanche Divides (Spad) na Photompiplipliprie (Sipm) nibyinshi bya sisitemu ya DTOF. Ipasizi zitandukanijwe nubushobozi bwabo bwo gusubiza amafotono imwe, gukurura ikibanza gikomeye na fototon imwe gusa, bikaba byiza kubikorwa byo gupima neza. Ariko, ingano nini ya pigiseli ugereranije na resiso gakondo ya CMO igabanya imyanya ya sisitemu ya DTOF.

Igihe-Kuri-Digital Guhindura (TDC)

Umuzunguruko wa TDC uhindura ibimenyetso bya Analoge mubimenyetso bya Digital byahagarariwe mugihe, gufata umwanya mwiza buri pulse yanditswe. Uku kuri kwukuri ni ngombwa kugirango tumenye umwanya wikintu cyintego ukurikije amateka ya histogram ya posshi.

Gucukumbura Ibipimo bya DTOF

Gutahura urutonde kandi ukuri

Urwego rwa sisitemu ya DTOF TELEFILE TOLTERS TOUST KUBYEREKEYE KUBYEREKEYE MU BIKORWA BY'UMUKAZA BISHOBORA GUKORA KANDI BITANZWE KUGARAGAZA CYIZA, RITONDE MU BURENGANZIRA. Kubaguzi ba elegitoroniki, iBibabirinze ni intera 5m, gukoresha VCELS, mugihe porogaramu zimodoka zishobora gusaba kumenya amanota 100 cyangwa zirenga, bisaba ikoranabuhanga ritandukanye nka eels cyangwafibre lasers.

Kanda hano kugirango umenye byinshi kubicuruzwa

Intera ntarengwa idasobanutse

Umubare ntarengwa udafite ubudaco biterwa nintera iri hagati yimpapuro zasohotse hamwe nigumya inshuro ya laser. Kurugero, hamwe nuburyo bushimishije bwa 1mHz, urwego rudasobanutse rushobora kugera kuri 150m.

ICYEMEZO

Precision muri sisitemu ya DTOF iranze bigarukira ku bugari bwa laser, mu gihe amakosa ashobora kuvuka mu buryo butandukanye mu bigize, harimo n'umushoferi wa laser, na TDC Nency. Ingamba nko gukoresha igiciro kirashobora gufasha kugabanya aya makosa ushiraho ibirindiro byigihe nintera.

Urusaku no kurwanya Interfence

Sisitemu ya DTOF igomba guhangana nurusaku rwinyuma, cyane cyane mubidukikije. Tekinike nko gukoresha pigiseli nyinshi zifite urwego rutandukanye rushobora gufasha gukemura iki kibazo. Byongeye kandi, ubushobozi bwa DTOF bwo gutandukanya ibitekerezo bitaziguye kandi byinshi byongera kwivanga.

Icyemezo cyo guhinduranya no gukoresha amashanyarazi

Iterambere muri Spid Technology, nkinzibacyuho kuva kumurika imbere (FSI) kugirango bimurikire. BSI) Iterambere, ihujwe na kamere ya DTOF ya sisitemu ya DTOF, ibisubizo muburyo bwamashanyarazi ugereranije na sisitemu ikomeje kubaho nkayo.

Ejo hazaza h'ikoranabuhanga rya DTOF

Nubwo inzitizi nyinshi nigiciro cya tekiniki zijyanye na tekinoroji ya DTOF, ibyiza byayo mubyukuri, intera, nububasha bituma umukandida asezeranya kubisabwa ejo hazaza muburyo buzaza muburyo buzaza muburyo buzaza mubikorwa bitandukanye. Nkuko Ikoranabuhanga rya Sensor hamwe na elegitoronike igishushanyo mbonera cya sisitemu yo kurera kwa DTOF

Kwamagana:

Turatangaza ko amwe mumashusho yerekanwe kurubuga rwacu yakusanyijwe kuri enterineti na Wikipedia, hagamijwe guteza imbere uburezi no gusangira amakuru. Twubaha uburenganzira bwumutungo wubwenge kubaremu bose. Gukoresha aya mashusho ntabwo bigenewe inyungu zubucuruzi.
Niba wemera ko icyaricyo cyose cyakoreshejwe kirenga ku burenganzira bwawe, nyamuneka twandikire. Dufite ubushake bwo gufata ingamba zikwiye, harimo gukuraho amashusho cyangwa gutanga ikiranga gikwiye, kugirango tumenye amategeko n'amabwiriza y'ubwenge. Intego yacu ni ugukomeza urubuga rukungahaye kubirimo, ruboneye, kandi rwubaha abandi umutungo bwite wubwenge.
Nyamuneka twandikire kuri aderesi imeri ikurikira:sales@lumispot.cn. Twiyemeje gufata ingamba zihita tubonye kumenyesha no kwemeza ubufatanye 100% mugukemura ibibazo byose.
