Laser technology yog siv nyob rau hauv ntau qhov chaw, qhov twg yuav tsum tau ntsuas meej thiab nyob rau hauv kev sib txuas lus. Qhov no txhais tau hais tias lawv yog ib qho tseem ceeb rau txhua yam ntawm tus kheej - tsav tsheb mus rau hauv fiber ntau optic internet thiab nrhiav cov pa roj hauv huab cua.
Tam sim no, ib pab pawg tshawb fawb tau tuaj nrog hom tshiab laser uas daws tau ntau yam teeb meem cuam tshuam nrog - hnub lasers tam sim no. Cov pab pawg yog coj los ntawm Associate Professor Johann Riemensberger ntawm NTNU's Department of Electronic Systems.
Riemensberger hais tias "Peb cov txiaj ntsig tuaj yeem muab rau peb hom tshiab laser uas yog ob qho tib si nrawm, pheej yig, muaj zog thiab siv tau yooj yim," Riemensberger hais.
Txoj haujlwm yog kev sib koom tes ntawm NTNU thiab Swiss École Polytechnique Fédérale de Lausanne (EPFL) thiab Luxtelligence SA. Cov hauj lwm yog luam tawm nyob rau hauv phau ntawv journalNtuj Photonics.
Tus kheej - tsav tsheb thiab lub tshuab ntsuas huab cua zoo
Pa precision lasers tuaj yeem loj, kim, thiab nyuaj rau kho.
Riemensberger hais tias "Peb lub laser tshiab daws ob peb yam teeb meem no,"
Qhov no txhais tau hais tias lub laser no tuaj yeem siv rau tus kheej - tsav tsheb, piv txwv li. Cov tsheb no siv cov txheej txheem kho qhov muag pom qhov chaw hu ua Lidar txhawm rau txheeb xyuas thiab txiav txim qhov kev ncua deb ntawm cov khoom hauv lawv ib puag ncig.
Cov txheej txheem ntsuas lub sij hawm sib txawv los yog hloov nyob rau hauv yoj theem ntawm lub teeb emissions ntawm lub laser thiab dab tsi yog reflected rov qab. Qhov no laser ntsuas nrog high precision, nyob ib ncig ntawm plaub centimeters.
Cov kws tshawb fawb kuj tau txais txiaj ntsig zoo thaum lawv siv lub laser los kuaj xyuas cov pa hydrogen cyanide hauv huab cua. Qhov no yog ib qho tshuaj lom neeg uas peb feem ntau hu ua "hydrocyanic acid." Nws muaj tshuaj lom heev hauv cov koob tshuaj me me, yog li nws tuaj yeem yog qhov tseem ceeb kom kuaj tau sai.
Advanced cov ntaub ntawv, microscopic circuits
Cov kws tshawb fawb tau tsim lub laser tshiab nrog cov ntaub ntawv siab heev thiab cov teeb pom kev hauv microscopic.
Lub laser emits lub teeb muaj zog thiab ruaj khov ntawm lub teeb. Ntawm lwm qhov zoo ntawm lub laser yog tias cov neeg siv tuaj yeem kho qhov zaus tau yooj yim thiab du, tsis tas li dhia.
"Koj tuaj yeem tswj tau yooj yim nrog tsuas yog ib qho kev tswj hwm xwb tsis muaj ntau," Riemensberger taw qhia.
Lub laser yog tsim los siv chip technology uas twb muaj lawm. Qhov no ua rau nws muaj peev xwm ua kom huab hwm coj- tsim nws pheej yig.
Riemensberger tau hais tias "Peb qhov kev tshawb pom ua rau nws muaj peev xwm tsim me me, pheej yig thiab cov neeg siv khoom siv-cov cuab yeej ntsuas tus phooj ywg thiab cov cuab yeej sib txuas lus nrog kev ua haujlwm siab," Riemensberger tau hais.
