Sau npe rau peb cov social media kom tau txais cov ntawv tshaj tawm sai

Cov lasers tau dhau los ua ib qho tseem ceeb rau kev siv tiv thaiv, muab cov peev xwm uas cov riam phom ib txwm tsis tuaj yeem sib piv. Cov blog no delves rau hauv qhov tseem ceeb ntawm lasers hauv kev tiv thaiv, hais txog lawv qhov kev ua tau zoo, kev ua kom raug, thiab kev nce qib thev naus laus zis uas tau ua rau lawv yog lub hauv paus ntawm kev ua tub rog niaj hnub no.

Kev Taw Qhia

Kev pib siv tshuab laser tau hloov pauv ntau yam kev lag luam, suav nrog kev sib txuas lus, tshuaj, thiab tshwj xeeb, kev tiv thaiv. Lasers, nrog lawv cov khoom tshwj xeeb ntawm kev sib koom ua ke, monochromaticity, thiab lub zog siab, tau qhib qhov ntev tshiab hauv kev muaj peev xwm ua tub rog, muab kev ua haujlwm raug, kev zais cia, thiab kev hloov pauv uas muaj txiaj ntsig zoo hauv kev ua tsov rog niaj hnub no thiab cov tswv yim tiv thaiv.

Kev Ntsuas thiab Kev Ntsuas Tseeb

Cov lasers muaj npe nrov rau lawv qhov tseeb thiab qhov tseeb. Lawv lub peev xwm los tsom mus rau cov hom phiaj me me ntawm qhov deb heev ua rau lawv tsis tseem ceeb rau cov ntawv thov xws li kev xaiv lub hom phiaj thiab kev taw qhia foob pob hluav taws. Cov txheej txheem tsom mus rau laser siab daws teeb meem ua kom muaj kev xa khoom raug, txo qhov kev puas tsuaj ntxiv thiab txhim kho cov nqi ua tiav ntawm lub luag haujlwm (Ahmed, Mohsin, & Ali, 2020).

Kev Siv Tau Ntau Yam Hauv Txhua Lub Platform

Qhov kev hloov pauv ntawm cov lasers hla ntau lub platform - los ntawm cov khoom siv tes mus rau cov tshuab loj uas tau teeb tsa hauv tsheb - qhia txog lawv qhov kev hloov pauv tau yooj yim. Cov lasers tau ua tiav kev koom ua ke rau hauv av, dej hiav txwv, thiab huab cua platforms, ua haujlwm ntau lub luag haujlwm suav nrog kev soj ntsuam, kev nrhiav lub hom phiaj, thiab cov riam phom ncaj qha rau kev tawm tsam thiab kev tiv thaiv. Lawv qhov me me thiab lub peev xwm los kho rau cov ntawv thov tshwj xeeb ua rau cov lasers yog qhov kev xaiv yooj yim rau kev ua haujlwm tiv thaiv (Bernatskyi & Sokolovskyi, 2022).

Kev Sib Txuas Lus Zoo Dua thiab Kev Soj Ntsuam

Cov txheej txheem sib txuas lus siv laser muab txoj hauv kev ruaj ntseg thiab ua haujlwm tau zoo rau kev xa cov ntaub ntawv, tseem ceeb rau kev ua haujlwm tub rog. Qhov tsis tshua muaj feem cuam tshuam thiab nrhiav tau ntawm kev sib txuas lus laser ua kom muaj kev sib pauv cov ntaub ntawv ruaj ntseg, lub sijhawm tiag tiag ntawm cov chav, txhim kho kev paub txog qhov xwm txheej thiab kev sib koom tes. Ntxiv mus, lasers ua lub luag haujlwm tseem ceeb hauv kev saib xyuas thiab kev soj ntsuam, muab cov duab daws teeb meem siab rau kev sau cov ntaub ntawv txawj ntse yam tsis muaj kev nrhiav pom (Liu et al., 2020).

Riam Phom Zog Uas Tau Tswj Xyuas

Tej zaum qhov kev siv lasers tseem ceeb tshaj plaws hauv kev tiv thaiv yog raws li cov riam phom muaj zog (DEWs). Lasers tuaj yeem xa lub zog sib xyaw rau lub hom phiaj kom ua puas tsuaj lossis rhuav tshem nws, muab lub peev xwm tawm tsam meej nrog kev puas tsuaj tsawg kawg nkaus. Kev tsim cov tshuab laser muaj zog siab rau kev tiv thaiv foob pob hluav taws, kev rhuav tshem drone, thiab kev tsis muaj peev xwm ntawm lub tsheb qhia txog lub peev xwm ntawm lasers los hloov pauv thaj chaw ntawm kev sib ntaus sib tua tub rog. Cov kab ke no muaj cov txiaj ntsig zoo dua li cov riam phom ib txwm muaj, suav nrog kev ceev ntawm lub teeb xa mus, tus nqi qis ib zaug, thiab lub peev xwm los koom nrog ntau lub hom phiaj nrog qhov tseeb siab (Zediker, 2022).

Hauv kev siv tiv thaiv, ntau hom laser siv, txhua hom ua haujlwm sib txawv raws li lawv cov yam ntxwv thiab peev xwm tshwj xeeb. Nov yog qee hom lasers siv ntau hauv kev siv tiv thaiv:

Hom Laser Siv Hauv Kev Tiv Thaiv

Cov Lasers Khoob (SSLs)Cov lasers no siv cov khoom siv tau zoo, xws li iav lossis cov khoom siv crystalline uas muaj cov khoom tsis tshua muaj. SSLs siv dav rau cov riam phom laser muaj zog heev vim lawv muaj zog tso zis siab, ua haujlwm tau zoo, thiab zoo ntawm lub teeb. Lawv tab tom raug sim thiab xa mus rau kev tiv thaiv foob pob hluav taws, kev rhuav tshem drone, thiab lwm yam kev siv riam phom ncaj qha (Hecht, 2019).

Cov Lasers FiberCov laser fiber siv cov fiber optical fiber doped ua qhov nce nruab nrab, muab cov txiaj ntsig zoo ntawm kev ywj pheej, qhov zoo ntawm lub teeb, thiab kev ua haujlwm zoo. Lawv tshwj xeeb tshaj yog nyiam rau kev tiv thaiv vim lawv qhov me me, kev ntseeg siab, thiab yooj yim ntawm kev tswj hwm thermal. Cov laser fiber siv rau hauv ntau yam kev siv tub rog, suav nrog cov riam phom muaj zog siab, lub hom phiaj tsim, thiab cov txheej txheem tiv thaiv (Lazov, Teirumnieks, & Ghalot, 2021).

Cov Tshuaj LasersCov tshuaj lasers tsim lub teeb laser los ntawm cov tshuaj tiv thaiv. Ib qho ntawm cov tshuaj lasers paub zoo tshaj plaws hauv kev tiv thaiv yog Chemical Oxygen Iodine Laser (COIL), siv rau hauv cov tshuab laser hauv huab cua rau kev tiv thaiv foob pob. Cov lasers no tuaj yeem ua tiav cov theem zog siab heev thiab ua haujlwm tau zoo rau qhov deb ntev (Ahmed, Mohsin, & Ali, 2020).

Cov Tshuab Laser Semiconductor:Kuj tseem hu ua laser diodes, cov no yog cov lasers me me thiab ua haujlwm tau zoo siv rau ntau yam kev siv los ntawm cov ntsuas qhov ntev thiab cov hom phiaj xaiv mus rau infrared countermeasures thiab twj tso kua mis rau lwm cov tshuab laser. Lawv qhov me me thiab kev ua haujlwm tau zoo ua rau lawv haum rau cov tshuab tiv thaiv portable thiab tsheb-mounted (Neukum et al., 2022).

Cov Lasers Uas Muaj Qhov Ntsug Thiab Qhov Cavity (VCSELs)VCSELs tso tawm lub teeb laser perpendicular rau ntawm qhov chaw ntawm lub wafer tsim thiab siv rau hauv cov ntawv thov uas xav tau kev siv hluav taws xob tsawg thiab cov qauv me me, xws li cov kab ke sib txuas lus thiab cov sensors rau kev siv tiv thaiv (Arafin & Jung, 2019).

Cov Laser Xiav:Cov thev naus laus zis laser xiav tab tom raug tshawb nrhiav rau kev siv tiv thaiv vim nws cov yam ntxwv nqus tau zoo dua, uas tuaj yeem txo lub zog laser uas xav tau ntawm lub hom phiaj. Qhov no ua rau cov laser xiav tuaj yeem yog cov neeg sib tw rau kev tiv thaiv drone thiab kev tiv thaiv foob pob hypersonic, muab qhov ua tau ntawm cov kab ke me dua thiab sib dua nrog cov txiaj ntsig zoo (Zediker, 2022).
