Lub sijhawm teem sijhawm-ntawm-davhlau (DTOF) yog ib qho kev ntsuas lub davhlau ntawm lub teeb, siv lub sijhawm daws teeb meem ib lub photon suav (TCSPC). Cov tshuab no yog qhov tseem ceeb rau ntau qhov kev siv, los ntawm kev sib thooj ntawm cov khoom siv hluav taws xob rau kev siv cov ntawv thov ua lag luam hauv cov ntawv thov hauv tsheb. Ntawm nws cov tub ntxhais, dtof Systems muaj ntau cov khoom tseem ceeb, txhua qhov ua si ib lub luag haujlwm tseem ceeb hauv kev ntsuas qhov tseeb.
Cov Txheej Txheem Qaum Ntawm Dtof Systems
Laser tsav tsheb thiab laser
Tus Laser Tsav, ib feem ntawm transmitter Circuit Coeccuit Court, tsim cov cim digital cov cim qhia los tswj cov laser tsom ntawm Mosfet hloov. Lasers, tshwj xeebNtsug kab noj hniav saum npoo emitting lasers(VCSELS), yog kev pom zoo rau lawv qhov nqaim spectrum, lub zog siv zog loj, kev siv lub peev xwm sai sai, thiab muab kev sib xyaw. Nyob ntawm daim ntawv thov, wavelengths ntawm 850nm lossis 940nM tau raug xaiv los sib npaug ntawm Secar spectrum nqus peaks thiab sensor quantiency.
Kev xa mus thiab tau txais Optics
Nyob rau sab transmitting, ib qho yooj yim kho qhov muag lossis kev sib xyaw ua ke ntawm cov iav lo ntsiab muag thiab cov khoom siv hloov pauv ntawm txoj kev xav ntawm kev xav. Qhov tau txais Optics, tsom rau kev sib sau teeb nyob rau hauv lub hom phiaj teb ntawm lub hom phiaj pom, muaj txiaj ntsig los ntawm cov roj ntsha uas muaj txiaj ntsig, nrog rau cov ntxaij lim dej kom tshem tawm cov kev cuam tshuam sib xws.
Spad thiab Sipm sensors
Ib leeg-photon avalanche diodes (spdor) thiab silicon photom omomultipiers (SIPM) yog thawj lub sensors hauv dtof systems. Spads yog qhov txawv los ntawm lawv lub peev xwm los teb ib lub photons ib leeg, ua rau muaj zog avalanche tam sim no nrog tsuas yog ib lub photon, ua rau lawv pom zoo rau kev ntsuas siab. Txawm li cas los xij, lawv loj dua pixel loj piv rau ib txwm muaj kev sib tw nrog cov spatial daws teeb meem ntawm dtof systems.
Lub sijhawm-rau-digerter (TDC)
Lub Circcuit Cocuit Coalog cim rau cov cim digital ua lub luag haujlwm digital sawv cev los ntawm lub sijhawm, ntes lub sijhawm tshwj xeeb uas txhua lub photon mem tes tau sau tseg. Qhov tseeb yog qhov tseem ceeb rau kev txiav txim siab txoj hauj lwm ntawm lub hom phiaj uas cov histogram ntawm sau cov pulses.
Tshawb nrhiav DTOF kev ua haujlwm tsis ua haujlwm
Nrhiav tau ntau ntau thiab raug
Kev tshawb nrhiav ntau ntawm DTOF System theoretically txuas ntxiv raws li nws lub teeb pulses tuaj yeem taug kev thiab tau pom rov qab los ntawm suab nrov. Rau cov neeg siv khoom siv hluav taws xob, lub hom phiaj feem ntau tsis pub dhau 5m ntau, siv cov ntawv thov vCSELS, thaum ntau dua, yuav tsum tau kuaj xyuas cov thev naus laus zis sib txawv xws li eels lossiscoers.
Nyem qhov no kom paub ntau ntxiv txog cov khoom
Qhov siab tshaj plaws unambiguous ntau
Qhov ntau tshaj plaws uas tsis muaj kev tsis meej xwm nyob ntawm lub caij nyoog ntawm lub sij hawm nruab nrab ntawm emulted pulses thiab qhov ntsuas zaus ntawm lub laser. Piv txwv li, nrog rau kev ntsuas zaus ntawm 1mHz, qhov tsis muaj kev kawm tsis tau tuaj yeem ncav cuag li 150m.
Precision thiab Yuam Kev
Precision hauv dtof system yog inherently txwv los ntawm cov mem tes dav ntawm ntau yam tsis paub, suav nrog tus laser tsav, thiab TDC Circuit Court. Cov tswv yim xws li ua haujlwm Spad tuaj yeem pab txo cov kev ua yuam kev no los ntawm kev tsim cov hauv paus rau lub sijhawm.
Suab nrov thiab cuam tshuam tsis kam
DTOF system yuav tsum sib cav nrog cov suab keeb kwm yav dhau, tshwj xeeb hauv lub teeb muaj zog. Cov tswv yim xws li siv ntau Spad pixels nrog sib txawv ntawm cov qib muaj peev xwm tuaj yeem pab tswj qhov kev sib tw no. Ib qho ntxiv, DTOF lub peev xwm kom paub qhov txawv ntawm kev ncaj qha thiab muaj kev cuam tshuam nws txoj kev cuam tshuam rau kev cuam tshuam.
Kev daws teeb meem zoo nkauj thiab siv hluav taws xob
Kev nce qib hauv Spad Sensor thev naus laus zis, xws li kev hloov pauv ntawm Ta-sab Absacation (FSI) rau tom qab-sab Illumination (BSI) cov txheej txheem, tau txhim kho cov txheej txheem photon uas muaj peev xwm hloov kho thiab sensor efficiency. Qhov kev vam meej no, ua ke nrog cov pulsed xwm ntawm dtof systems, cov txiaj ntsig hauv kev noj hluav taws xob qis dua los txuas ntxiv nthwv dej zoo li nws yog lub.
Lub neej yav tom ntej ntawm DTof Technology
Txawm hais tias muaj kev cuam tshuam zoo thiab cov nuj nqis cuam tshuam nrog DTof Technology, ntau yam, thiab lub zog ua haujlwm tau ua rau nws muaj kev sib tw yav tom ntej hauv ntau thaj teb. Raws li sensor thev naus laus zis thiab hluav taws xob tsim txuas ntxiv mus evolve, DTOF systems hauv cov khoom siv hluav taws xob, kev nyab xeeb hauv tsheb, thiab dhau mus.
