Laser Illuminator

Laser Iguminators: los ntawm cov ntsiab cai tseem ceeb rau kev ua ke siab hauv EO / IR ISRT system

 

Laser illuminators (lossis abrev. Li)  yog cov khoom siv tshwj xeeb uas tshem cov teeb ci ntsa iab los txhim kho pom kev pom hauv qis - lub teeb lossis ib puag ncig pom. Tsis zoo li cov teeb tsa ib txwm muaj xws li leds lossis halogen teeb, laser illuminators tau ua ibnqaim, tsom cov nqaj ntawm monochromatic teeb, muab ntau dua, kev siv, thiab tswj. Cov cuab yeej thev naus laus zis tau hloov kho los ntawm cov kev siv cov neeg siv khoom yooj yim rau kev txawj ua tub rog, qhov twg nws sib xyaw ua ke, tshuaj xyuas, thiab hom phiaj).

 

Peb ntawm no qhia cov qauv ntawm cov roj av tsim thiab lawv cov kev sib xyaw nrogEO / ir Isrt Systems, kev nce qib los ntawm cov neeg pej xeem siv rau cov tub rog tshaj lij, suav nrog cov thev naus laus zis.

 

 

Kev Taw Qhia Yooj Yim rau Laser Iguminators

 

Ntawm lawv cov tub ntxhais, laser imuminators ua haujlwm ntawm lub hauv paus ntawm kev txhawb nqa atom Cov wavelengths xws liinfrared (ir, 700-1550 nm)Rau cov kev ua haujlwm sib tw, raws li lawv tsis pom rau tib neeg lub qhov muag tab sis kuaj tau los ntawm hmo ntuj.

 

Cov ntsiab lus tseem ceeb ntawm laser illuminators tshaj cov teeb pom kev zoo yog:

• High collimation (minimal nqaj divergence),
• monochromaticity (tib xim rau kev sib piv zoo dua), thiab
• efficiency (tsawg hluav taws xob noj rau cov zis siab).

 

Hauv cov ntawv thov thooj kho kab, laser illuminators yog siv nyob rau hauv cov koob yees duab kev ruaj ntseg, kho lub zeem muag hmo ntuj, thiab kev saib xyuas tsiaj qus. Piv txwv li, ib qho yooj yim nir laser illuminator ua ke nrog CCTV lub koob yees duab tuaj yeem txuas ntxiv cov kev soj ntsuam kom zoo rau 100-2-200 meters hauv kev tsaus ntuj. Cov kab ke no feem ntau ntiavNruam nthwv dej (CW) lasersnrog lub zog tawm ntawm 1-5 watts, kom ntseeg tauQhov muag Kev Nyab Xeeb Qhov muagdhauChav kawm 1 lossis 1m kev ntaus nqi hauv qab IEC 60825 qauv.

 

Kev sib xyaw ua ke ncaj qha: tus illuminator mounting coaxially nrog lub koob yees duab, synchronizing nrog nws cov chaw dej nyab xeeb nrog, uas yog tom qab ntawd lawv - rhiab sensors.

 

 

Kev sib xyaw nrog eo / ir isrt systems

 

EO / ir Isrt Tshuab Ua kePom lub teeb (EO) koob yees duab, infrared (ir) sensors, thiabHom Phiajrau kev paub txog kev kawm thoob. Laser illuminators txhim kho cov txheej txheem no los ntawm cov neeg ua haujlwm ua haujlwm ntawm lub teeb, them nyiaj rau passive ir txwv hauv qis - sib piv lossis duab ntxoo scenes. Kev sib xyaw ua ke cuam tshuam nrog cov nqaj laser nrog lub sensor's denor's denal's oxis, feem ntau siv beam nthuav dav lossis diffusers kom phim cov fov.

 

Hauv kev teeb tsa pej xeem, xws li cov neeg soj ntsuam ciam teb lossis kev soj ntsuam kev lag luam, laser illuminators txhim kho cov duab zoo tsis muaj lub teeb sab nraud. Piv txwv li, 850 nm laser tuaj yeem txhawb nqa eo lub koob yees duab ua haujlwm hauv huab lossis haus luam yeeb, qhov twg, nrov tawm tsam nrog suab nrov. Lub teeb tsa feem ntau suav nrog lub zog hluav taws xob, tswj hluav taws xob rau mem tes ua, thiab software rau kev siv hluav taws xob tsis siv neeg raws li lub teeb pom kev zoo.

 

Tsiv mus rau cov tub rog - Kev sib koom ua ke qib ua ke los ua kev sib xyaw ua ke ISRT platform tsheb (UAVs) lossis av- raws li cov turrets. Ntawm no, lawv pab tau "Cov Duab Ua Haujlwm, "Qhov twg lub pulse pulses nrog rhiab lub rooj vag kom txo qis ntawm cov khoom siv tsis zoo. Qhov no yog cov cua daj cua dub los yog nag.

 

 

Los ntawm dog dig rau cov tub rog cov ntawv thov: Lub luag haujlwm ntawm kev sib tw thev naus laus zis

 

Doger doger illuminators ua haujlwm hauvCW hom, muab kev tu ncua tsis tu ncua rau luv -} txoj kab haujlwm. Hauv cov neeg siv khoom siv drones lossis hauv tsev kev ruaj ntseg, lawv txuas lub zeem muag hmo ntuj rau 50-100 meters, nrog rau kev tswj tau yooj yim / tawm.

 

Ntawm lubkev ua tub rog theem,Pulsed lasers ua haujlwm tau ntev ntev li ntev dua (txog 5 km, lossis ntau ntev ntev). Kev sib xyaw nrog eo / ir isrt cuam tshuam cov khoom - Lub xeev lasers (piv txwv li} Piv txwv li, nyob rau hauv lub tsheb-mounted systems, tus Illuminator AIDS hauv kev txheeb xyuas kev hem thawj thaum hmo ntuj saib xyuas, nrog Beam shaping rau cov chaw dav.

 

Cov kev siv tub rog ua kom paub Gating tshuab,Lub sijhawm -} synchronized txoj kev uas tsa nce qib. Gated laser illuminators mem duab hauv luv (nanoseconds), thiab lub ntsej muag rov qab los ntawm huab, nag, lossis haus luam yeeb. Qhov no yog ua raws lub sijhawm - ntawm {4 4}} davhlau cov ntsiab cai, zoo sib xws rau cov kev ua kom muaj kev xav.

 

Nyob rau hauv high -}}} - gating kom ua tiav "pom- los ntawm" muaj peev xwm. Piv txwv li, ib qho 1550 nm qhov muag -}}}}}}}}}}}}}}} kev hloov pauv ntawm 50-100% hauv cov nyom huab cua. Cov tub rog sib txawv feem ntau sib xyaw ua ke Optics thiab Ai rau kev ua siab loj sib txuas, kho cov mem tes dav dav dav raws li kev deb thiab cov xwm txheej. Hauv qee qhov chaw sov lossis huab cua sov los ntawm huab cua los nag, qhov twg cov khaub ncaws ci tshwm sim yuav luag txhua hnub, cov tshuab sib tw tswj hwm tswj hwm 1-1.5 km tib neeg taug qab. Txawm tias muaj kev lees paub, raws li pom hauv customized tshwj xeeb eo / ir system.

 

Kev ua siab loj kuj ua rau "burst illumination" rau kev ua haujlwm covert, kev pheej hmoo tau txais kev tiv thaiv tsawg. Hauv ISRT kev koom ua ke, lub laser synchronizes nrog irFocal dav hlau arrays (FPAs), siv thev naus laus zis zoo liTxhuam CCD (ICCD)lossisLuv - wave ir (swir)Sensors rau sub {{0} microsecond gating, ua tiav cov kev daws teeb meem nqes mus rau centimeters.

 

 

Cov kev sib tw thiab yav tom ntej

 

Thaum cov txheej txheem laser errumin txhim kho ISRT, cov kev sib tw muaj xws li kev tswj hwm kev nyab xeeb rau kev nyab xeeb (limkal kev tswj hwm) thiab thermal kev tswj hwm hauv kev cog lus kev cog lus. Cov tub rog ua tub rog ua yeeb yaj kiab qhov no nrog chav kawm 1m thiab nqaj divergence tswj.

 

Yav tom ntej sib tw taw tes rauNtau -} specuminators sib xyaw NIR thiab Swirrau kev nthuav dav dav dav, ua ke nrog AI rauNkaus nyob hauv lub hom phiajCov. Raws li kev tsis sib haum xeeb sib zog,gated laser - eo / irHybrids yuav dhau los ua cov qauv kev tiv thaiv, muab cov tsis muaj kev pom tseeb hauv cov chaw sib tw.

 

Hauv cov ntsiab lus, laser illuminators hloov pauv EO / ir isrt los ntawm passive cov neeg ua kom nquag plias, hloov los ntawm hmo pom kev ua yeeb yam rau gated tub rog willohouses. Lawv sib koom ua ke ua ke drives precision hauv kev soj ntsuam, ua kom muaj kev ua haujlwm tshaj tawm thoob plaws pej xeem thiab kev tiv thaiv.
