Vim li cas Laser Kev Tiv Thaiv Kev Nyab Xeeb tseem ceeb?

Lub hom phiaj tseem ceeb ntawmKev Tiv Thaiv Laseryog los txo cov laser puas rau cov neeg ua haujlwm thiab cov khoom siv. Qhov no suav nrog kev tiv thaiv lub qhov muag los ntawm kev puas tsuaj laser, tiv thaiv cov tawv nqaij kub hnyiab, tsis txhob muaj hluav taws kub thiab tawg, tiv thaiv kev raug mob rau lwm tus, thiab ua kom muaj kev ua raws li tag nrho cov kev cai thiab cov qauv.

Yuav kom ua tiav cov hom phiaj no, muaj ntau yam kev tiv thaiv tuaj yeem ua tau. Piv txwv li, koj tuaj yeem siv cov tsom iav tshwj xeeb laser tiv thaiv lossis laser tiv thaiv qhov ncauj qhov ntswg los tiv thaiv koj ob lub qhov muag; Thaum ua haujlwm laser, koj yuav tsum sim kom tsis txhob ncaj qha laser irradiation ntawm daim tawv nqaij; rau cov khoom siv laser uas tuaj yeem tsim kom muaj cua sov ntau, kev tiv thaiv tsim nyog yuav tsum tau ua, siv nyob rau hauv chav ua haujlwm tag nrho ntawm lub laser, lub qhov rais tiv thaiv laser tuaj yeem ntsia tau los soj ntsuam kev ua haujlwm. Thaum ua haujlwm laser, xyuas kom meej tias lub laser tsis txhob tsoo cov neeg tsis sib haum xeeb los yog tsiaj txhu kom ntseeg tau tias muaj kev nyab xeeb ntawm kev ua haujlwm laser.

A. Muaj peev xwm muaj kev nyab xeeb ntawm lasers rau cov neeg ua haujlwm thiab cov khoom siv
Laser thev naus laus zis tau siv dav, txawm li cas los xij, thaum siv, cov neeg ua haujlwm thiab cov khoom siv yuav ntsib qee qhov kev pheej hmoo ntawm kev nyab xeeb. Ua ntej ntawm tag nrho cov, laser kev puas tsuaj rau lub qhov muag yog ntau dua vim hais tias lub laser beam yog ib tug sib npaug zos beam nrog ib tug me me divergence lub kaum sab xis, uas ua rau lub laser lub zog yuav tsum concentrated nyob rau hauv ib tug nyias nyias thiab tsom mus rau ib tug heev me me qhov chaw ntawm lub laser. retina los ntawm lub lens. . Tsis tas li ntawd, lasers kuj tseem tuaj yeem ua rau tawv nqaij kub hnyiab, hluav taws kub thiab lwm yam kev phom sij.

Tsis tas li ntawd, qee qhov kev siv lasers tuaj yeem cuam tshuam cov kuab tshuaj thiab lwm yam khoom siv hluav taws xob, thiab tseem ua rau kub kub lossis molten hlau. Cov teeb meem uas tsis yog kab teeb ci tuaj yeem ua rau muaj kev phom sij rau lub neej xws li hluav taws xob poob siab, hluav taws kub, thiab ua tsis taus pa.
Hauv kev teb rau cov kev pheej hmoo no, International Electrotechnical Commission tus qauv (IEC 60825-1) faib cov khoom siv laser rau hauv xya chav kawm raws li lawv qhov wavelength thiab siab tshaj tawm lub zog laser. Ntawm lawv, Class 3R lasers yuav tsum tau hnav cov iav tiv thaiv laser rau kev ua haujlwm. Nyob rau tib lub sijhawm, kev tuav tswj kom zoo thiab txwv kev sib cuag ncaj qha nrog lub teeb ci laser tuaj yeem txo qhov kev pheej hmoo ntawm kev raug mob, xws li tsim kom muaj lub rooj cob qhia tag nrho ntawm lub laser thiab txhim kho lub qhov rais tiv thaiv laser rau kev tiv thaiv thiab kev soj ntsuam.

B. Qhov tseem ceeb thiab qhov tsim nyog ntawm kev tiv thaiv laser
Tiv thaiv qhov muag kev nyab xeeb: Tib neeg lub qhov muag yog lub cev muaj zog tshaj plaws rau kev puas tsuaj rau laser. Yog tias ob lub qhov muag raug ncaj qha rau lub teeb muaj zog laser, nws yuav ua rau cov tawv nqaij kub hnyiab, uas tuaj yeem ua rau qhov muag tsis pom qhov mob hnyav. Yog li ntawd, koj yuav tsum hnav cov tsom iav uas tsim nyog los yog daim npog ntsej muag thaum ua haujlwm laser los tiv thaiv koj ob lub qhov muag ntawm laser puas.

Zam kev puas tsuaj ntawm daim tawv nqaij: Ntxiv nrog rau qhov muag, daim tawv nqaij kuj yog ib qho chaw raug rau laser puas. Tshwj xeeb tshaj yog rau qee lub zog lasers, xws li xiav lossis ntsuab laser pointers, yog tias lawv ncaj qha irradiated ntawm daim tawv nqaij, lawv yuav ua rau tawv nqaij kub hnyiab. Yog li ntawd, thaum ua haujlwm laser, koj yuav tsum sim kom tsis txhob ncaj qha laser irradiation ntawm daim tawv nqaij.

Tiv thaiv hluav taws kub thiab tawg: Qee hom khoom siv laser ua kom muaj cua sov ntau, uas yuav ua rau hluav taws kub lossis tawg yog tias tsis ua haujlwm zoo. Piv txwv li, qee cov khoom siv laser muaj zog yuav tsim kom muaj qhov kub thiab txias thaum ua haujlwm. Yog tias cov cuab yeej no overheat los yog tsis muaj cua sov dissipation, nws yuav ua rau hluav taws. Yog li ntawd, kev tiv thaiv hluav taws tsim nyog yuav tsum tau ua thaum siv cov khoom siv laser.

Tsis txhob ua rau lwm tus raug mob: Yog tias lub laser tsis muaj kev tiv thaiv zoo lossis tswj tsis tau, nws yuav ua rau pom lwm tus neeg lossis tsiaj txhu, ua rau lawv raug mob. Yog li ntawd, thaum ua haujlwm lub laser, koj yuav tsum xyuas kom meej tias lub laser tsis txhob tsoo cov neeg tsis sib xws lossis tsiaj txhu.

Ua raws li cov kev cai tswj hwm: Ntau lub teb chaws thiab cheeb tsam muaj cov kev cai thiab cov qauv hais txog kev siv lasers. Piv txwv li, hauv Tebchaws Meskas, raws li US Occupational Safety and Health Administration (OSHA), cov tswv ntiav haujlwm yuav tsum muab cov cuab yeej tiv thaiv tsim nyog thiab kev cob qhia los tiv thaiv cov neeg ua haujlwm los ntawm kev raug mob laser hauv chaw ua haujlwm. Yog li ntawd, cov kev cai thiab cov qauv yuav tsum tau ua raws li thaum ua haujlwm lasers.

C. Daim ntawv thov dav ntawm laser thiab laser kev tiv thaiv kev nyab xeeb
Kev siv dav ntawm laser stems los ntawm nws cov yam ntxwv. Laser yog ib tug monochromatic lub teeb yoj nrog ib tug heev nqaim ntau zaus thiab muaj peev xwm mloog tau siab zog nyob rau hauv ib tug nqaim txoj kev. Yog li ntawd, lub teeb tsom laser tuaj yeem siv los laum, vuam, txiav thiab lwm yam haujlwm ntawm ntau yam ntaub ntawv.

Tshwj xeeb, lasers tau dav siv hauv kev lag luam, kev kho mob, kev lag luam, kev tshawb fawb, cov ntaub ntawv thiab kev ua tub rog. Piv txwv li, nyob rau hauv kev lag luam teb, lasers tuaj yeem ua cov khoom zoo thiab kev ntsuas ntsuas; hauv kev kho mob, lasers tuaj yeem siv rau kev kho mob thiab kuaj mob; nyob rau hauv kev lag luam teb, laser npav thiab lwm yam technologies yog dav siv. Tsis tas li ntawd, muaj ntau ntau lwm yam kev siv laser, xws li lidar, laser riam phom, laser cov ntaub ntawv, laser pom kev kho, laser kev zoo nkauj, laser scanning, laser yoov tshaj cum tua, thiab tsis muaj kev puas tsuaj rau cov cuab yeej.

Cov kev siv tshwj xeeb ntawm kev tiv thaiv laser yog dav heev, suav nrog kev kho mob, kev lag luam, tub rog thiab lwm yam kev lag luam, nrog rau physics, chemistry, biology thiab ib puag ncig kev tshawb fawb thiab lwm yam kev qhuab qhia. Hauv kev kho mob, piv txwv li, kev tiv thaiv cov khoom siv laser tuaj yeem tiv thaiv cov neeg ua haujlwm kho mob thiab cov neeg mob los ntawm laser puas. Tshwj xeeb tshaj yog, cov khoom siv tiv thaiv laser muaj xws li laser tiv thaiv iav, laser tiv thaiv tsom iav, laser tiv thaiv tsom iav, laser tiv thaiv qhov ncauj qhov ntswg, laser tiv thaiv iav, laser tiv thaiv phab ntsa, laser tiv thaiv curtains, thiab lwm yam. Lawv tau dav siv nyob rau hauv qhov chaw xws li CD thiab DVD recorders.

Hauv kev tsim khoom lag luam, tshwj xeeb tshaj yog cov cheeb tsam uas cuam tshuam nrog kev ua haujlwm laser, xws li laser txiav, vuam, thiab lwm yam, cov kev ntsuas laser tiv thaiv kuj yuav tsum tau coj los ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm. Tsis tas li ntawd, laser kev tiv thaiv tshuab rau optoelectronic imaging systems yog lwm qhov tseem ceeb daim ntawv thov teb, uas feem ntau muaj xws li cov ntaub ntawv tiv thaiv thiab xam cov duab los tiv thaiv laser dig muag, thiab kho qhov muag system tsim thiab cov duab ua los tiv thaiv laser dig muag. kiv taub hau.

Tsis tas li ntawd, nrog kev txhim kho sai ntawm lasers, laser kev nyab xeeb thiab kev tiv thaiv ntawm cov cuab yeej kho qhov muag pom tseeb thiab cov khoom siv engineering kuj tau txais kev saib xyuas dav. Qhov no suav nrog cov kev txwv ntawm ntau yam ntawm cov hluav taws xob laser, kev ntsuas cov cuab yeej siv niaj hnub thiab kev saib xyuas, thiab kev txhim kho thiab siv cov ntaub ntawv tiv thaiv, xws li absorbing cov ntaub ntawv tiv thaiv, cov ntaub ntawv tiv thaiv kev tiv thaiv, cov ntaub ntawv tiv thaiv kev sib xyaw, thiab lwm yam. Cov no yog tag nrho cov no kom muaj kev nyab xeeb ntawm daim ntawv thov. laser tshuab.
