Laser gravage screen, qhov twg xim liab dhau los ntawm cov mesh.
Cov mesh yog them los ntawm ib txheej polymer nyias, uas yog sau nrog ib tus kab teeb laser uas yuav qhib qhov lub qhov nyob hauv qhov chaw uas nws yog engraved. Qhov no yog ib txoj hauv kev zoo ntawm kev tsim cov ntawv luam tawm hlau thiab cov thawv, tshwj xeeb tshaj yog thaum nws tawm mus siab ntim tshuab luam ntawv. Yuav luag tag nrho cov luam ntawv rau textiles, carpets, wallpapers thiab banknotes siv tau cov txheej txheem no.
Qhov teeb meem ncaj qha ntawm cov pa roj carbon monoxide CO2 tsuas yog siv li ntawm 10kHz, vim yog cov metastable nitrogen, uas yog ib feem ntawm qhov laser roj sib tov. Cov tshuab tam sim no siv los luam ntawm cov hlab ntsha thiab cov kaus poom yuav tsum muaj ntau dua cov suab pauv, ntawm qhov kev txiav txim ntawm ob peb puas kilohertz. Qhov no yog vim feem ntau ntawm cov kev cai daws teeb meem dua thiab tsis yog vim cov qauv tseeb ntawm cov khoom siv. Cov mesh engraved yog ib tug txheej txheem 2D, thaum lub phaj ntawv luam tawm thiab cov polymer los yog rubber rau cov menyuam yog cov txheej txheem 3D txheej txheem uas muaj cov qauv nyuaj. Txhua tus qauv uas sau ncaj nraim yuav tsum muaj lub hauv paus ruaj khov rau hauv cov txheej txheem luam ntawv, thiab lawv yuav muaj qhov nyuaj geometries rau sab saum toj, xws li tus qauv zoo thiab kev pabcuam kom them nyiaj rau qhov nyiaj tau nce.
