Intelligent High-Tech - Laser, Yuav Siv Li Cas Hauv Lub Neej
Nrog rau txoj kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub no, kev siv tshuab laser tau nthuav dav thoob plaws peb lub neej thiab muaj feem cuam tshuam nrog peb. Tab sis thaum nws los txog rau laser, ntau tus neeg tej zaum yuav tsis paub, yog li niaj hnub no, cia's tham txog qhov no, cov khoom siv high-tech uas yog ob qho tib si paub thiab tsis paub rau peb—laser.
Laser txoj kev xav tau tshawb pom los ntawm tus kws tshaj lij physicist Einstein hauv xyoo 1916. Nws yog ib hom teeb uas muaj zog los ntawm kev txhawb zog hluav taws xob. Piv txwv li, tag nrho kev siv, thiab kev siv spatiotemporal faib tawm.
Tom qab 42 xyoo, uas yog, xyoo 1958, nws tau ua tiav thawj zaug. Niaj hnub no, qhov kev tsim kho zoo tshaj plaws no tau siv dav hauv kev ua tub rog, kev sib txuas lus, kev tshawb fawb thiab thev naus laus zis, kev ntsuas, kev kho mob, kev lag luam, kev ua liaj ua teb thiab ntau yam haujlwm, thiab tau ua rau cov haujlwm no tshwm sim. Ua ntej los ntawm leaps thiab ciam teb, txawm tias lub ntiaj teb hloov pauv.
Kev siv tshuab laser hauv tub rog
Laser thev naus laus zis tau npog ntau qhov chaw hauv cov tub rog: xws li kev tshawb nrhiav thiab kev tso chaw, kev sib txuas lus, kev taw qhia, kev tswj hluav taws, riam phom laser, thiab lwm yam.
1) Laser kev taw qhia: tuaj yeem siv tau kom txog thaum lub hom phiaj raug rhuav tshem. Laser kev taw qhia muaj siab precision thiab muaj zog tiv thaiv kev cuam tshuam muaj peev xwm.
2) Laser ntau thiab laser radar: Nws muaj qhov zoo ntawm qhov deb, raug, nrawm, tiv thaiv kev cuam tshuam, thiab tsis muaj qhov muag tsis pom.
3) Laser reconnaissance thiab confrontation: siv lub lens optical kom tau txais cov echoes, ua optical scanning reconnaissance ntawm tus yeeb ncuab, thiab siv laser blinding riam phom los rhuav tshem lawv, los yog siv jammers los cuam tshuam rau lawv ib txwm ua hauj lwm.
4) Laser riam phom: laser aiming daws qhov teeb meem ntawm aiming hmo ntuj;
Kev siv laser hauv kev kho mob
Nrog rau kev txhim kho txuas ntxiv ntawm laser thev naus laus zis, laser thev naus laus zis tau ua tiav zoo hauv kev kho mob.
Rau myopia, kev kho mob phais feem ntau pib los ntawm ob yam, ib qho yog hloov lub lens nrog curvature sib txawv, thiab lwm qhov yog hloov lub diopter ntawm lub cornea. Txawm li cas los xij, kev hloov lub lens tsis yog qhov tseeb rau cov tub ntxhais hluas, tab sis cov txheej txheem phais ib txwm tsis tuaj yeem ua tiav cov txiaj ntsig ntawm kev hloov lub vojvoog ntawm curvature ntawm lub cornea. Tom qab kev sim thiab kev tshawb fawb, nws paub tias lub vojvoog ntawm curvature ntawm lub cornea yuav tsum tau hloov nyob rau hauv 3 hli ntawm qhov chaw ntawm lub qhov muag. Laser thev naus laus zis tuaj yeem ua qhov no vim tias nws tuaj yeem hloov kho hauv qhov loj me me.
Laser marking tshuab
Laser npav: Nws yog siv laser rau ib nrab irradiate lub workpiece yuav tsum tau cim, thiaj li yuav tawm ilv, mus tas li thiab meej cov cim.
Qhov zoo ntawm laser npav tshuab daim ntawv thov yog:
1) Laser npav tuaj yeem ua rau ntau yam cim, cim thiab cov qauv, thiab lwm yam, thiab tuaj yeem ua tau raws li microns, uas ua rau nws nyuaj rau cov neeg cuav hloov pauv, yog li ua lub luag haujlwm tiv thaiv cov khoom cuav.
2) Tsis muaj kev sib cuag nrog lub workpiece, tsis muaj kev txiav quab yuam, thiab thermal cuam tshuam me ntsis, uas tuaj yeem ua kom qhov tseeb ntawm cov khoom ua haujlwm, thiab tuaj yeem ua rau saum npoo ntawm cov khoom siv ntau yam, nrog cov cim zoo thiab ua haujlwm zoo.
3) Thaum lub laser ua thiab lub computer cov lej tswj kev siv tshuab yog networked, cov khoom siv ua haujlwm tsis zoo yog tsim, uas tuaj yeem ua tiav cov haujlwm yooj yim, hloov kho yooj yim thiab ua haujlwm siab.
4) Lub laser npav tshuab kuj muaj qhov zoo ntawm tsis muaj kuab paug thiab tus nqi qis, uas qhib qhov kev cia siab rau kev ua haujlwm niaj hnub thiab ntau lawm.
Tam sim no, ntxiv rau cov ntawv thov saum toj no, laser thev naus laus zis tseem suav nrog kev txiav, vuam, drilling, engraving, ntsuas, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, aerospace thiab lwm yam kev lag luam.
