Lasers tau hloov pauv ntau yam kev lag luam, los ntawm kev kho mob mus rau kev tsim khoom, vim lawv lub peev xwm los tsim cov teeb pom kev zoo ntawm lub teeb uas tuaj yeem txiav, duab, lossis kos cov ntaub ntawv nrog qhov tseeb. Txawm li cas los xij, lub zog uas ua rau lasers muaj txiaj ntsig zoo kuj tseem tuaj yeem ua rau muaj kev phom sij, tshwj xeeb tshaj yog rau lub qhov muag, tawv nqaij, thiab ib puag ncig. Kab lus no yuav tham txog kev phom sij, kev tiv thaiv, thiab kev coj ua zoo tshaj plaws uas ua kom muaj kev nyab xeeb siv laser.
Laser Hazards
Lasers tuaj yeem tsim kev puas tsuaj rau peb txoj kev: thermal, photochemical, thiab mechanical. Kev puas tsuaj cua sov tshwm sim los ntawm laser beam lub tshav kub, uas tuaj yeem ua rau kub hnyiab, thaum photochemical kev puas tsuaj tshwm sim los ntawm laser beam lub peev xwm los hloov cov ntaub so ntswg 'cov tshuaj lom neeg muaj pes tsawg leeg, ua rau kev puas tsuaj ntawm tes. Kev puas tsuaj, ntawm qhov tod tes, tshwm sim los ntawm laser beam lub cev quab yuam, uas tuaj yeem ua rau cov ntaub so ntswg puas.
Lasers raug cais raws li lawv lub peev xwm ua rau muaj kev phom sij, xws li Chav Kawm 1 (kev pheej hmoo qis tshaj) mus rau Chav Kawm 4 (muaj kev pheej hmoo siab tshaj). Qhov kev faib tawm yog nyob ntawm qhov siab tshaj plaws tso cai raug (MPE) rau lub teeb ci laser, uas yog qhov siab tshaj plaws ntawm cov hluav taws xob laser uas tuaj yeem nqus tau yam tsis muaj kev phom sij. Cov yam tseem ceeb uas txiav txim siab MPE suav nrog lub laser lub wavelength, lub zog, thiab beam txoj kab uas hla, nrog rau lub sij hawm raug.
Hom Kev Tiv Thaiv Laser
Ntau qhov kev tiv thaiv tuaj yeem txo qhov kev pheej hmoo cuam tshuam nrog kev siv laser, suav nrog kev tiv thaiv qhov muag, kev tiv thaiv tawv nqaij, thiab kev tiv thaiv ib puag ncig.
Kev Tiv Thaiv Qhov Muag
Kev tiv thaiv qhov muag yog qhov kev tiv thaiv tseem ceeb tshaj plaws, vim qhov muag tshwj xeeb raug rau kev puas tsuaj rau laser. Laser tsom iav kev nyab xeeb, tsom iav, lossis daim npog ntsej muag uas txo qis (txo) lub teeb ci laser yog cov hom kev tiv thaiv qhov muag tshaj plaws. Attenuation yog ua tiav los ntawm cov ntxaij lim dej uas tsuas yog tso cai rau cov wavelengths ntawm lub teeb kom dhau, yog li tshem tawm cov kev phom sij.
Tiv thaiv tawv nqaij
Kev tiv thaiv ntawm daim tawv nqaij yog tsim nyog thaum siv lasers uas emit ultraviolet (UV) los yog infrared (IR) hluav taws xob, vim hais tias cov wavelengths yuav ua rau muaj kev puas tsuaj rau daim tawv nqaij. Cov khaub ncaws, xws li lub tes tsho ntev, hnab looj tes, thiab ris, ua raws li lub cev tiv thaiv ntawm daim tawv nqaij thiab lub teeb laser, yog li txo qhov kev pheej hmoo ntawm kev puas tsuaj.
Kev tiv thaiv ib puag ncig
Kev tiv thaiv ib puag ncig yog tsim nyog los tiv thaiv kev phom sij ntawm laser, xws li hluav taws kub, tawg, thiab hluav taws xob poob siab, uas tuaj yeem ua rau muaj kev puas tsuaj rau tib neeg thiab cov khoom puas. Cov ntaub thaiv npog uas ua rau lub cev muaj kev cuam tshuam ntawm lub laser thiab ib puag ncig, nrog rau cov kev coj ua kom raug hluav taws xob thiab hluav taws xob, xws li hauv av, kev sib txuas, thiab hluav taws xob tua hluav taws, yog cov kev tiv thaiv tseem ceeb uas ua kom muaj kev nyab xeeb ntawm ib puag ncig.
Cov kev coj ua zoo tshaj plaws rau kev siv laser nyab xeeb
Ntau qhov kev coj ua zoo tshaj plaws kom muaj kev nyab xeeb siv laser, suav nrog:
1. Kev soj ntsuam kev pheej hmoo: Ua ntej siv lub laser, ua qhov kev soj ntsuam kev pheej hmoo uas ntsuas cov kev phom sij cuam tshuam nrog lub laser, qhov muaj peev xwm raug, thiab cov kev tswj hwm tsim nyog kom txo qhov kev pheej hmoo.
2. Kev cob qhia: xyuas kom txhua tus neeg ua haujlwm uas yuav siv lub laser tau txais kev cob qhia tsim nyog, uas suav nrog cov kev phom sij cuam tshuam nrog lub laser, kev tswj hwm tsim nyog los txo qhov kev pheej hmoo, thiab kev siv thiab kev saib xyuas ntawm lub laser.
3. Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE): Xyuas kom txhua tus neeg ua haujlwm uas yuav siv lub laser muaj kev nkag tau thiab siv PPE tsim nyog, xws li laser tsom iav, khaub ncaws, thiab cov ntaub thaiv npog, raws li qhov xav tau.
4. Cov txheej txheem kev khiav hauj lwm: Tsim thiab ua raws li cov txheej txheem kev khiav hauj lwm uas txhais cov kauj ruam uas yuav tsum tau ua kom muaj kev nyab xeeb ntawm lub laser, nrog rau cov kauj ruam uas yuav tsum tau pib, khiav lag luam, thiab kaw lub laser, nrog rau kev tiv thaiv kev sib tsoo ntawm lub laser beam thiab tiv thaiv tsis tau tso cai. nkag mus rau lub laser.
5. Kev Saib Xyuas thiab Kev Tshawb Fawb: Tsim thiab ua raws li lub sijhawm saib xyuas thiab kev tshuaj xyuas tsis tu ncua rau lub laser thiab nws cov khoom, suav nrog cov khoom siv laser, cov khoom siv hluav taws xob, cov tshuab cua txias, thiab cov khoom siv kho qhov muag, kom ntseeg tau tias lub laser ua haujlwm zoo.
6. Cov txheej txheem xwm txheej ceev: Tsim thiab sib txuas lus cov txheej txheem xwm txheej ceev uas txhais cov kauj ruam uas yuav tsum tau teb rau cov xwm txheej kub ntxhov ntawm laser, xws li kev raug mob ntawm qhov muag, hluav taws kub, thiab hluav taws xob shocks.
7. Kev khaws cia: Tsim thiab tswj cov ntaub ntawv ntawm cov haujlwm laser, suav nrog cov ntaub ntawv qhia kev cob qhia, cov ntaub ntawv khaws cia, thiab cov ntaub ntawv xwm txheej, kom ntseeg tau tias cov ntaub ntawv tsim nyog muaj nyob rau yav tom ntej siv.
