Wararka - Mabda 'aasaasiga ah iyo adeegsiga tof (waqtiga duulista)

Kusoo dhawow warbaahinta bulshada ee boostada degdegga ah

Taxanadan ayaa ujeedadiisu tahay in la siiyo akhristayaasha oo leh mid qoto dheer iyo faham horumar leh ee nidaamka duulista (tof) nidaamka. Waxyaabaha ay ka kooban tahay waxay daboolaysaa dulmar guud oo ku saabsan nidaamyada TOF, oo ay kujirto sharaxaad faahfaahsan oo ah labadaba tof (ptof) iyo Toof Tooska ah (DTOF). Qeybahani waxay dib ugula dhaqmaan cabbiraadaha nidaamka, faa'iidooyinkooda iyo faa'iido darrooyinkooda, iyo algorithms kala duwan. Maqaalka ayaa sidoo kale sahaminaya qaybaha kala duwan ee nidaamyada TOF, sida dusha sare ee daloolka toosan ee la soo xijiya lasers (vcsels), muraayadaha indhaha, oo helaya dareemayaal sida CIS, APD, iyo wareegga darawalka sida Casics.

Hordhac TOF (waqtiga duulista)

Mabaadi'da aasaasiga ah

Tof, oo u taagan waqtiga duulista, waa hab loo isticmaalo in lagu cabbiro masaafada isaga oo xisaabaya waqtiga ay u qaadanayso in iftiinku u safro masaafo gaar ah oo dhexdhexaad ah. Mabda 'Mabda' waxaa ugu horrayn lagu dabaqayaa seenyaalaha topical toptional waana mid toos ah. Hawshu waxay ku lug leedahay il iftiin ah oo ku xiraya nalka iftiinka, iyadoo waqtiga laga duubay. Iftiinkan ayaa markaa ka muuqda bartilmaameedka, waxaa qabtaa qaataha, iyo waqtiga soo dhaweynta ayaa la xusayaa. Farqiga u dhexeeya waqtiyadan, ayaa loo muujiyey in t, go'aamisa masaafada (D = xawaaraha iftiinka (c) ×) × t / 2).

Noocyada dareemayaasha tof

Waxaa jira laba nooc oo ka mid ah dareemayaasha TOF: indhaha ku habboon iyo electromagnetic. Dareemayaasha tof ee indhaha, kuwaas oo ka badan, u adeegso galmada khafiifka ah, sida caadiga ah tirada indrared-ka, si loogu cabiro masaafada. Burmooyinkan ayaa laga soo saaraa dareenka, ka tarjuma shay, oo ku soo noqo dareenka, halkaas oo waqtiga safarka lagu cabiro loona isticmaalo in lagu xisaabiyo masaafada. Taas bedelkeeda, dareemayaasha elektaroonigga ah ee elektaroonigga ah waxay isticmaalaan hirarka elektaroonigga ah, sida radar ama lidar, si loo cabbiro masaafada fog. Waxay ku shaqeeyaan mabda 'la mid ah laakiin waxay isticmaalaan dhexdhexaad ka duwancabirka masaafada.

Codsiyada dareemayaasha tof

Dareennada tof ayaa ah kuwo isku dhafan oo lagu dhex daray qaybo kala duwan:

Robotics:Loo adeegsaday ogaanshaha carqaladeynta iyo hagidda. Tusaale ahaan, robots sida qolka 'Glalba iyo' Boston Dynamics 'ee ka shaqeeya kaamirooyinka qoto-dheer ee loo yaqaan' TOKT 'oo loogu talagalay khariidaynta agagaarkooda iyo dhaqdhaqaaqa qorshaynta.

Nidaamyada amniga:Caaweeya dareemayaasha mooshinka ee lagu ogaanayo kuwa wax galka ah, kicinta digniinta, ama dhaqdhaqaaqa nidaamyada kamaradaha.

Warshadaha baabuurta:Waxaa lagu soo daray nidaamyada gargaarka-darawalka ee xakamaynta kontoroolka maraakiibta la-qabsiga iyo ka-hortagga shilka, oo si isdaba joog ah ugu badan yahay moodallada gaariga cusub.

Garoon caafimaad: Waxaa loo shaqeeyaa sawirka aan caqabadaha iyo ogaanshaha, sida toroccation viccal tomography (Oktoobar), oo soo saara sawirrada unugyada xalka ah.

Elektaroonigga macaamiisha: Isku-darka taleefanka casriga ah, kiniiniga, iyo laptops-ka, iyo laptops loogu talagalay astaamaha sida sunta wejiga, xaqiijinta biometric, iyo aqoonsiga jimicsiga.

Diyaaradaha aankaani:Waxaa loo adeegsaday in lagu wajaho badhanka, ka-hortagga shilka, iyo wax ka qabashada welwelka gaarka loo leeyahay iyo kuwa duulista

Taariikhda nidaamka

Nidaam cayiman oo TOF ah wuxuu ka kooban yahay dhowr qaybood oo muhiim ah oo lagu gaaro cabirka masaafada sida lagu sharaxay:

· Gudbinta (TX):Tan waxaa ku jira ilo iftiin leh oo laser ah, badiyaa aVCER, Darawalka Darawalka Asic inuu kaxeeyo laser-ka, iyo qaybaha indhaha ee kantaroolka ilaalka sida isku dhaca muraayadaha indhaha ama waxyaabaha kaladuwan ee kaladuwan, iyo miirayaasha.
· Qaataha (RX):Tani waxay ka kooban tahay muraayadaha indhaha iyo miirayaasha dhamaadka, dareemayaasha sida CIS, Spad, ama kabitaan ku saleysan nidaamka TOF, iyo processor sector sector (isp) si ay uga baaraandegaan xaddiga lacageed ee badan ee laga soo qaado chip-ka qaddarka.
·Maareynta Awoodda:Maareynta xasilloonXakamaynta hadalka ee hadda ee VCSoos iyo korantada sare ee loo yaqaan 'ruugyada' produs 'waa muhiim, oo u baahan maareyn awood adag.
· Lakabka software:Tan waxaa ku jira firmware, sdk, OS, iyo lakabka dalabka.

Qaab dhismeedka wuxuu muujinayaa sida laambadda laser, oo asal ahaan ka soo jeeda VCESE oo ay wax ka beddeshay qaybaha indhaha, waxay ku safraan meel bannaan, oo ay ka tarjumaan shay, oo ay ku soo noqdaan qaataha. Xisaabinta waqtiga lugta ee howshani waxay muujisaa masaafada ama faahfaahinta qotodheer. Si kastaba ha noqotee, qaab dhismeedkaasi ma daboolayo wadiiqooyinka qaylada, sida dhawaqa qorraxda ee iftiinka qoraxda ama dhawaqa badan oo ka soo baxa milicsiga, oo laga wada hadlo taxanaha dambe ee taxanaha.

Kala-saaridda nidaamyada TOF

Nidaamyada TOF waxaa ugu horreyn lagu tilmaamaa farsamooyinka cabbiraadda masaafada: Tooska Tooska (DTOF) iyo Toof) iyo Toof), mid walbana leh qalab kala duwan iyo habab algorithic ah. Taxanaha ayaa markii hore soo saaray mabaadii'dooda ka hor intaanay u dhicin falanqayn isbarbardhiga ku saabsan faa'iidooyinkooda, caqabadaha, iyo cabbirrada nidaamka.

In kasta oo ay u muuqato mabda'a muuqda ee tof - oo soo kabanaya garaaca wadnaha iftiinka iyo ogaanshaha soo laabashada si loo xisaabiyo masaafada - kakanaanta waxay ku dhacdaa iftiinka soo laabashada iftiinka. Tan waxaa looga hadlayaa iyada oo loo eegayo iftiinka iftiinka dhalaalaya si loo gaaro saamiga ugu dhawaaqa-dhawaaqa ah iyo xulashada hirarka ku habboon si loo yareeyo faragelinta iftiinka deegaanka. Qaab kale ayaa ah in lagu soo afjaro iftiinka kombiyuutarka si looga dhigo mid lagu kala soocayo markii la soo celiyo, oo la mid ah calaamadaha SOS oo leh toosh ah toosh.

The series proceeds to compare dTOF and iTOF, discussing their differences, advantages, and challenges in detail, and further categorizes TOF systems based on the complexity of information they provide, ranging from 1D TOF to 3D TOF.

qiyaasbo

Taariikhda tooska ah ee tooska ah ayaa si toos ah u cabirtaa waqtiga duulista ee Photon. Qeybta ugu weyn, oo ah avulanche doode diode (spad), waa mid xasaasi ah oo ku filan in la ogaado sawirrada keligood ah. DTOF waxay u shaqaysaa waqtiga tirinta sawir ee isku xidhka (TCSPC) si loo cabbiro waqtiga codbixinta, dhisida taariikh-yar si ay uga jareen masaafada ugu badan ee ku saleysan soo noqnoqda ugu badan ee farqi ugu sarreeya.

jir u

Tooska tooska ah ee tooska ah waxay xisaabisaa waqtiga duullimaadyada iyadoo lagu saleynayo farqiga wejiga ee u dhexeeya suuxdinta iyo jawiga la helay, oo caadi ahaan loo adeegsado mawjadaha joogtada ah ama calaamadaha isbadalka garaaca wadnaha. Spof waxay isticmaali kartaa naqshadeeyeyaasha sawirka heerka caadiga ah, cabiridda xoojinta nalka waqti ka dib.

ITOOF waxaa loo sii kala qaybiyaa mowduuca mowduuca ee joogtada ah (CW-otof) iyo moodalka garaaca wadnaha (pulsed-of). CW -TOF waxay cabirtaa wareejinta wajiga ee udhaxeysa iyo mowjadaha salaantu, halka pasted-otof ay xisaabiso wareejinta wejiga iyadoo la adeegsanayo calaamadaha mowjadaha labajibaaran.
