Dab tsi yog Cov Txheej Txheem Kev Tiv Thaiv Laser?

Kev Tiv Thaiv Lasercoj cov kev tiv thaiv kev nyab xeeb tiv thaiv kev phom sij ntawm laser rau tib neeg lub cev thiab chaw ua haujlwm. Nws lub hom phiaj tseem ceeb yog kom zam thiab txo cov teeb meem laser hluav taws xob ntau npaum li sai tau thiab txo qhov muaj peev xwm ntawm tib neeg lub cev, tshwj xeeb tshaj yog qhov muag thiab tawv nqaij, raug rau cov hluav taws xob laser. Tshwj xeeb, lub hom phiaj tseem ceeb ntawm kev tiv thaiv laser muaj xws li tiv thaiv laser dig muag thiab tiv thaiv laser dazzling. Laser kev tiv thaiv technologies rau optoelectronic imaging systems feem ntau yog muab faib ua ob pawg: ib tug yog cov ntaub ntawv tiv thaiv, uas tiv thaiv laser blinding los ntawm absorbing los yog reflecting laser; Lwm qhov yog kev siv tshuab thev naus laus zis, uas tiv thaiv laser dazzling los ntawm optimizing cov duab ua algorithms.

Tsis tas li ntawd, txhawm rau ua kom tiav cov hom phiaj no, yuav tsum muaj ntau yam khoom siv tiv thaiv thiab thev naus laus zis, xws li laser tiv thaiv tsom iav, tsom iav tiv thaiv laser, laser tiv thaiv qhov ncauj qhov ntswg, laser tiv thaiv kaus mom hlau, thiab lwm yam, tib lub sijhawm, kev nyab xeeb tsim thiab siv laser cov cuab yeej siv thiab cov tshuab laser kuj tseem ceeb heev, suav nrog kev teeb tsa kev nyab xeeb siv, ntsuas cov cuab yeej siv tsis tu ncua thiab kev saib xyuas, thiab lwm yam.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txawm hais tias cov khoom siv tiv thaiv laser tuaj yeem daws teeb meem qee zaus laser raug mob, lawv tsis tuaj yeem tshem tawm tag nrho cov kev pheej hmoo. Yog li ntawd, thaum siv lasers, cov cai tswj kev nyab xeeb yuav tsum tau ua raws li nruj me ntsis kom ntseeg tau tias kev nyab xeeb ntawm cov neeg ua haujlwm.

B. Cov hauv paus ntsiab lus ntawm kev tiv thaiv laser
Muaj ob lub ntsiab lus tseem ceeb ntawm kev tiv thaiv laser, ib qho yog hom nqus thiab lwm yam yog hom kev xav. Kev tiv thaiv kev nqus tshuab yog ntxiv ntau yam absorbers rau iav lossis yas lo ntsiab muag. Cov absorbers no tuaj yeem nqus lub teeb laser thiab tiv thaiv kom tsis txhob hla lub lens. Cov cuab yeej tiv thaiv kev cuam tshuam yog los npog lub lens nrog cov txheej txheem siab refractive index dielectric films. Thaum lub teeb hits no dielectric zaj duab xis, txij li tag nrho cov teeb pom kev ntawm lub interface muaj tib theem, lub teeb pom kev ntawm lub wavelength no yuav txhim kho. Qhov kev tiv thaiv zoo li no tuaj yeem tsis tsuas yog muaj kev cuam tshuam lub teeb laser los tiv thaiv lub qhov muag, tab sis kuj muaj peev xwm xa mus rau lwm lub teeb pom kev zoo.

Tsis tas li ntawd, lwm txoj kev tiv thaiv yog laser kev tiv thaiv technology raws li cov ntaub ntawv hloov theem. Lub hauv paus ntsiab lus ntawm kev tiv thaiv thev naus laus zis no yog tias cov ntaub ntawv tiv thaiv raws li theem hloov hauv txoj cai yuav raug hloov mus rau theem hloov pauv raws li kev txhawb nqa sab nraud. Thaum lub sij hawm hloov cov txheej txheem, cov khoom kho qhov muag ntawm cov khoom yuav hloov nyob rau hauv ib lub sij hawm luv luv.

1. Reflection txoj cai thiab daim ntawv thov ntawm laser tiv thaiv
Lub hauv paus ntsiab lus ntawm kev tiv thaiv laser yog tsuas yog los npog lub lens nrog cov txheej txheem siab refractive index dielectric films. Thaum lub teeb hits no dielectric zaj duab xis, txij li tag nrho cov teeb pom kev ntawm lub interface muaj tib theem, lub teeb pom kev ntawm lub wavelength no yuav txhim kho. Qhov kev tiv thaiv zoo li no tuaj yeem tsis tsuas yog muaj kev cuam tshuam lub teeb laser los tiv thaiv lub qhov muag, tab sis kuj muaj peev xwm xa mus rau lwm lub teeb pom kev zoo. Tsis tas li ntawd, laser kev tiv thaiv tshuab raws li theem hloov cov ntaub ntawv kuj yog ib qho kev tiv thaiv kev siv niaj hnub no. Lub hauv paus ntsiab lus tseem ceeb yog tias cov ntaub ntawv tiv thaiv raws li lub hauv paus kev hloov pauv theem yuav raug hloov mus rau theem hloov pauv nyob rau hauv kev zoo siab rau sab nraud. Thaum lub sij hawm hloov cov txheej txheem, cov khoom kho qhov muag ntawm cov ntaub ntawv yuav hloov. Cov khoom tuaj yeem hloov pauv hauv lub sijhawm luv luv.

Hom tsom iav laser tiv thaiv no tau tsim thiab siv txij li xyoo 1970s. Nws qhov zoo dua yog tias nws tuaj yeem tiv thaiv laser irradiation ntawm cov wavelengths tshwj xeeb thiab ua tiav cov teebmeem tiv thaiv. Tshwj xeeb, nws tsuas yog siv cov khoom muaj txiaj ntsig ntawm cov khoom siv los cuam tshuam qhov teeb meem teeb meem kom ua tiav cov hom phiaj tiv thaiv. Nws yuav tsum raug sau tseg tias koj yuav tsum tsis txhob saib ncaj qha rau ntawm qhov chaw laser thaum hnav cov tsom iav laser, vim qhov no yuav ua rau koj lub qhov muag puas.

2. Txoj cai nqus thiab daim ntawv thov kev tiv thaiv laser
Lub hauv paus ntsiab lus ntawm kev tiv thaiv laser yog tsuas yog ntxiv ib lub teeb absorber ntawm ib lub wavelength tshwj xeeb rau cov khoom siv lens, thiab siv lub teeb pom kev zoo ntawm lub absorber kom nqus thiab tiv thaiv lub teeb ntawm cov wavelength sib thooj uas nws los rau hauv kev sib cuag nrog. Cov tshuab no tau tshwm sim thaum xyoo 1980s. Tshwj xeeb, thaum lub teeb laser ntawm ib lub wavelength tshwj xeeb hits lub lens, absorbers hauv lub lens nqus cov rays, tiv thaiv lawv los ntawm kev nkag mus rau lub qhov muag thiab ua rau muaj kev puas tsuaj.

Laser tiv thaiv tsom iav yog cov khoom lag luam uas siv txoj cai nqus dej no. Nws yuav tsum raug sau tseg tias koj yuav tsum tsis txhob saib ncaj qha rau ntawm qhov chaw laser thaum hnav cov tsom iav laser, vim qhov no yuav ua rau koj lub qhov muag puas. Tsis tas li ntawd, kev ruaj ntseg ntawm laser tiv thaiv tsom iav yuav tsum tswj lub teeb pom kev zoo hauv 5 vib nas this.

Nyob rau tib lub sijhawm, piv nrog cov tsom iav tsom iav tsom iav, qhov zoo ntawm cov tsom iav tiv thaiv laser yog tias nws muaj kev tiv thaiv ntawm txhua lub teeb ntawm lub teeb, tsis yog tsuas yog txwv rau ib lub wavelength tshwj xeeb. Txawm li cas los xij, nws qhov tsis zoo yog tias nws muaj kev cuam tshuam ntau dua rau kev pom thiab yuav ua rau muaj teeb meem xws li xim txawv.

3. Scattering txoj cai thiab daim ntawv thov kev tiv thaiv laser
Lub hauv paus ntsiab lus ntawm kev tiv thaiv laser feem ntau yog siv nyob rau hauv lub teeb scattering technology, uas yog ib txoj kev tiv thaiv raws li nonlinear optical qauv. Lub teeb tawg tshuab siv Brownian kev txav ntawm cov khoom kom ua rau muaj kev hloov pauv hauv lub teeb siv. Cov me me uas raug tshem tawm hauv cov kua lossis roj yuav txav mus tsis tu ncua. Thaum lub teeb dhau los ntawm cov colloids, cov khoom yuav tawg lub teeb. Tsis tas li ntawd, cov khoom siv kho qhov muag ntawm cov khoom siv saum npoo kuj tseem siv los ua kom muaj kev tiv thaiv laser tawg, xws li laser tiv thaiv zaj duab xis npaj los ntawm cov ntaub ntawv nanostructured. Cov yeeb yaj kiab no tuaj yeem ua tiav kev tiv thaiv los ntawm kev tawg qhov teeb meem.

Nws yog ib qho tsim nyog sau cia tias txawm tias siv txoj kev tiv thaiv twg los xij, nws yog ib qho tsim nyog yuav tau xaiv cov kev tiv thaiv tsim nyog raws li qhov tshwj xeeb laser tsis thiab siv ib puag ncig. Nyob rau tib lub sijhawm, cov khoom siv tiv thaiv, xws li hnav tsom iav tshwj xeeb, yuav tsum tau siv kom raug kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm.

4. Attenuation txoj cai thiab daim ntawv thov ntawm laser tiv thaiv
Lub hauv paus ntsiab lus ntawm kev tiv thaiv laser yog tsuas yog ua kom tsis muaj zog ntawm laser los ntawm kev nqus, kev xav lossis lub teeb tawg, thiaj li ua tiav lub hom phiaj ntawm kev tiv thaiv. Tshwj xeeb, attenuated laser tiv thaiv tsom iav siv lub hauv paus ntsiab lus no los lo lo ntsiab muag nrog ib txheej ntawm cov khoom uas tuaj yeem nqus tau lub teeb ntawm cov wavelengths tshwj xeeb. Thaum cov teeb ntawm cov wavelengths tshwj xeeb nkag mus rau cov lo ntsiab muag, lawv yuav raug nqus thiab hloov mus rau hauv lub zog cua sov. Qhov no ua tiav cov nyhuv ntawm attenuating laser siv.

Nws yog ib qho tsim nyog sau cia tias qee qhov teeb meem yuav tsum tau xav txog hauv kev siv tswv yim, xws li thermally induced deformation, cuam tshuam cuam tshuam, cuam tshuam polarization, spatial inhomogeneity thiab beam deflection. Tsis tas li ntawd, attenuated laser tiv thaiv tsom iav yog tsuas yog siv nyob rau hauv industrial teb, tshwj xeeb tshaj yog cov uas muaj xws li laser tej hauj lwm, xws li laser txiav, vuam, thiab lwm yam. Nws kuj yog lug siv nyob rau hauv cov tub rog teb thiab kev kho mob teb.
