Lub teeb ci xenon yog qhov siab - siv, lub teeb tam sim ntawd dav siv hauv kev yees duab, tshuaj, thiab kev lag luam. Nws txoj hauv kev ua haujlwm tseem ceeb yog ua raws li qhov tshwm sim luminescence ntawm cov pa roj tsawg xenon (Xe) nyob rau hauv qhov siab -voltage electric teb. Los ntawm kev tswj xyuas cov txheej txheem tso pa tawm kom meej, lub teeb xenon flash tuaj yeem tso tawm siab - lub teeb ci ntsa iab ze rau lub hnub ci spectrum nyob rau lub sijhawm luv luv, ua tau raws li qhov xav tau tam sim, lub teeb hnyav.
Basic Structure thiab Cheebtsam
Cov ntsiab lus tseem ceeb ntawm xenon flash teeb yog lub iav raj (feem ntau yog ua los ntawm quartz) uas muaj xenon roj. Hauv lub raj muaj ob lub electrodes -ib qho anode thiab cathode. Ib puag ncig lub tshuab nqus tsev siab yog khaws cia nruab nrab ntawm ob lub electrodes, uas tom qab ntawd tau ntim nrog siab - siab xenon roj (feem ntau ntawm ntau qhov chaw). Ib qho hluav taws xob sab nraud muab cov khoom siv hluav taws xob tsis ntev los no (txog li ob peb txhiab volts) rau lub teeb nyem ntawm lub chaw khaws cia capacitor, ua rau cov txheej txheem tso pa tawm.
Tshem tawm Luminescence Mechanism
Lub luminescence ntawm xenon flash teeb yog nyob ntawm lub hauv paus ntsiab lus ntawm cov pa tawm. Thaum lub siab -voltage pulse yog siv los ntawm sab nraud Circuit Court, xenon roj molecules ntawm cov electrodes yog ionized, tsim ib lub plasma muaj li dawb electrons thiab ions. Cov khoom them nqi no tau nrawm los ntawm lub zog hluav taws xob thiab sib tsoo nrog xenon atoms, zoo siab ntau atoms mus rau lub zog siab dua.
Thaum lub zog xenon atoms hloov los ntawm lawv lub zog siab rov qab mus rau lawv lub xeev hauv av, lawv tso lub zog nyob rau hauv daim ntawv ntawm photons. Vim lub zog theem qauv ntawm xenon atoms, lawv cov hluav taws xob spectrum npog lub teeb pom kev zoo (kwv yees li 400-800 nanometers) thiab zoo ib yam li hnub ci spectrum, uas ua rau lub teeb dawb uas tshwm nyob ze rau lub hnub ci ntuj. Cov txheej txheem no tshwm sim nyob rau hauv microseconds, ua rau lub teeb nyem los tsim cov flashes tam sim ntawd nrog lub zog siab tshaj plaws mus txog kaum tawm kilowatts.
Triggering thiab Energy Control
Pib lub teeb nyem xenon yuav tsum kov yeej cov roj tawg hluav taws xob (feem ntau 20-30 kilovolts). Hauv kev xyaum, qhov siab - zaus, high-voltage mem tes yog tsim los ntawm cov electrodes uas siv lub tshuab hluav taws xob los yog hluav taws xob ua hluav taws xob, pib qhov pib ionization avalanche cuam tshuam thiab txo qhov pib rau kev pib lub ntsiab tawm.
Txhawm rau kho lub sijhawm flash thiab lub zog, cov qauv tsim hluav taws xob feem ntau suav nrog lub kaw lus cia thiab qhov hluav taws xob tawm. Lub cia capacitor yog precharged mus rau pua pua mus rau phav phav volts, thiab lub zog tso tawm instantaneously los ntawm lub flash raj thaum tso tawm. Los ntawm kev kho lub peev xwm capacitor thiab them qhov hluav taws xob, lub sijhawm flash (feem ntau 1/1000 thib ob mus rau ob peb milliseconds) thiab lub teeb siv zog tuaj yeem tswj tau.
Application Advantages thiab Technical Features
Lub ntsiab zoo ntawm xenon flash teeb nyob rau hauv lawv lub siab brightness, luv mem tes ntev, thiab dav spectrum. Piv rau txuas ntxiv -yoj lub teeb qhov chaw zoo li LEDs, lawv cov luminous flux tam sim no tuaj yeem ncav cuag kaum tawm txhiab lumens, ua rau lawv haum rau siab -kev yees duab ceev lossis kev kho mob hauv qhov chaw qis- teeb pom kev zoo. Tsis tas li ntawd, qhov xwm txheej tas mus li ntawm xenon spectrum ua rau nws zoo heev rau cov ntawv thov uas xav tau cov xim zoo nkauj, xws li kev yees duab ID.
Txawm li cas los xij, xenon teeb nyem kuj muaj qhov tsis zoo xws li kev siv hluav taws xob siab, kev siv lub neej tsawg (feem ntau kaum tawm txhiab flashes), thiab kev cia siab rau siab -voltage circuits. Cov thev naus laus zis niaj hnub tau txhim kho lawv cov kev ruaj ntseg thiab cov lus teb nrawm dua los ntawm kev sib koom ua ke ntawm cov tshuab hluav taws xob tsav tsheb thiab ntau -pulse tswj.
Nyob rau hauv cov ntsiab lus, xenon flash teeb ua tau zoo, instantaneous lub teeb emission los ntawm lub hauv paus ntsiab lus ntawm cov pa paug. Lawv cov txheej txheem kev khiav hauj lwm sib koom ua ke plasma physics thiab Circuit Court tswj thev naus laus zis, ua rau lawv lub teeb pom kev tsis tuaj yeem hloov pauv hauv ntau qhov chaw.
