Laboratoireamakuru yumutekano
Mu myaka yashize, hamwe niterambere rihoraho ryinganda za laser,tekinoroji ya laseryahindutse igice kidatandukanijwe mubushakashatsi bwubumenyi, inganda nubuzima.Ku bantu bafite amashanyarazi bakora inganda za laser, umutekano wa laser ufitanye isano rya bugufi na laboratoire, ibigo n'abantu ku giti cyabo, kandi kwirinda kwangirika kwa lazeri kubakoresha byabaye ikintu cyambere.
A. Urwego rwumutekano rwalaser
Icyiciro1
1. Icyiciro1: Imbaraga za Laser <0.5mW.Lazeri itekanye.
2. Icyiciro1M: Nta kibi kiri mu mikoreshereze isanzwe.Mugihe ukoresheje indorerezi za optique nka telesikopi cyangwa ibirahuri bito binini, hazabaho ingaruka zirenze icyiciro cya 1.
Icyiciro2
1, Icyiciro2: imbaraga za laser ≤1mW.Guhita uhita munsi ya 0.25s bifite umutekano, ariko kubireba igihe kirekire birashobora guteza akaga.
2.
Icyiciro3
1, Icyiciro3R: imbaraga za laser 1mW ~ 5mW.Niba igaragara mugihe gito gusa, ijisho ryumuntu rizagira uruhare runini mukurinda urumuri, ariko niba urumuri rwinjiye mumaso yumuntu iyo rwibanze, bizangiza kwijisho ryumuntu.
2, Icyiciro3B: imbaraga za laser 5mW ~ 500mW.Niba ishobora kwangiza amaso mugihe urebye neza cyangwa ikagaragaza, muri rusange ni byiza kwitegereza ikwirakwizwa rya diffuse, kandi birasabwa kwambara amadarubindi yo kurinda laser mugihe ukoresheje uru rwego rwa laser.
Icyiciro4
Imbaraga za Laser:> 500mW.Nibyangiza amaso nuruhu, ariko kandi birashobora kwangiza ibikoresho hafi ya laser, gutwika ibintu byaka, kandi bigomba kwambara amadarubindi ya lazeri mugihe ukoresheje uru rwego rwa laser.
B. Kwangiza no kurinda laser kumaso
Amaso nigice cyoroshye cyane cyumubiri wumuntu kwangirika kwa laser.Byongeye kandi, ingaruka zishingiye ku binyabuzima za lazeri zirashobora kwegeranya, kabone niyo guhura rimwe bidatera ibyangiritse, ariko guhura kwinshi bishobora guteza ibyangiritse, abahohotewe na lazeri inshuro nyinshi bahura nijisho akenshi nta kirego kigaragara bafite, gusa bumva kugabanuka gahoro gahoro.Itaraikubiyemo uburebure bwose kuva ultraviolet ikabije kugeza kuri infragre.Ibirahuri birinda lazeri ni ubwoko bwikirahure kidasanzwe gishobora gukumira cyangwa kugabanya kwangirika kwa lazeri kumaso yumuntu, kandi nibikoresho byingenzi mubushakashatsi butandukanye bwa laser.
C. Nigute ushobora guhitamo indorerwamo nziza ya laser?
1, kurinda umurongo wa laser
Menya niba ushaka kurinda uburebure bumwe gusa cyangwa uburebure bwinshi icyarimwe.Ibirahuri byinshi birinda lazeri birashobora kurinda uburebure bumwe cyangwa bwinshi icyarimwe, kandi guhuza uburebure butandukanye birashobora guhitamo ibirahuri bitandukanye birinda laser.
2, OD: ubwinshi bwa optique (agaciro ko kurinda laser), T: guhererekanya umurongo urinda
Amadarubindi yo gukingira Laser arashobora kugabanywa murwego rwa OD1 + kugeza kuri OD7 + ukurikije urwego rwo kurinda (uko agaciro ka OD kari hejuru, umutekano urenze).Mugihe duhitamo, tugomba kwitondera agaciro ka OD kerekanwa kuri buri kirahure, kandi ntidushobora gusimbuza ibicuruzwa byose birinda laser hamwe na lens imwe ikingira.
3, VLT: itumanaho rigaragara (urumuri rudasanzwe)
"Kugaragara k'umucyo ugaragara" akenshi ni kimwe mu bipimo byirengagizwa byoroshye muguhitamo indorerwamo zo gukingira laser.Mugihe uhagarika laser, indorerwamo ikingira laser nayo izahagarika igice cyumucyo ugaragara, bigira ingaruka kubireba.Hitamo urumuri rwo hejuru rugaragara (nka VLT> 50%) kugirango byorohereze kwitegereza mu buryo butaziguye ibintu byageragejwe na laser cyangwa gutunganya laser;Hitamo urumuri rwo hasi rugaragara, rukwiranye nurumuri rugaragara ni ibihe bikomeye.
Icyitonderwa: Ijisho ryumukoresha wa lazeri ntirishobora kwerekezwa kumurongo wa lazeri cyangwa urumuri rwarwo rwerekanwe, nubwo kwambara indorerwamo ikingira laser bidashobora kureba neza kumurabyo (kureba icyerekezo cyuka cya laser).
D. Ibindi byo kwirinda no kurinda
Kuzirikana
1, mugihe ukoresheje lazeri, abahanga mubushakashatsi bagomba kuvanaho ibintu bifite isura igaragara (nk'amasaha, impeta na badge, nibindi, ni isoko ikomeye yo kwerekana) kugirango birinde kwangizwa numucyo ugaragara.
2, umwenda wa lazeri, urumuri rworoheje, rukusanya urumuri, nibindi, birashobora gukumira ikwirakwizwa rya lazeri no gutekereza nabi.Inkinzo yumutekano ya lazeri irashobora gufunga urumuri rwa lazeri murwego runaka, kandi ikagenzura uburyo bwa lazeri ikoresheje ingabo ikingira umutekano kugirango wirinde kwangirika.
E. Umwanya wa Laser no kwitegereza
1, kuri infragre, ultraviolet laser beam itagaragara kumaso yumuntu, ntutekereze ko kunanirwa kwa laser hamwe no kwitegereza amaso, kwitegereza, guhagarara no kugenzura bigomba gukoresha ikarita yerekana infragre / ultraviolet cyangwa igikoresho cyo kureba.
2, kuri fibre ihujwe na laser, ubushakashatsi bwakozwe na fibre, ntibizagira ingaruka gusa kubisubizo byubushakashatsi no gutuza, gushyira nabi cyangwa gushushanya bidatewe no kwimura fibre, icyerekezo cyo gusohoka cya laser icyarimwe cyahinduwe, nabyo bizazana bikomeye umutekano wumutekano kubashakashatsi.Gukoresha optique ya fibre optique kugirango ikosore fibre optique ntabwo itezimbere gusa ituze, ariko kandi irinda umutekano wubushakashatsi kurwego runini.
F. Irinde akaga nigihombo
1. Birabujijwe gushyira ibintu byaka kandi biturika munzira inyuramo.
2, imbaraga zimpanuka za laser pulsed ni ndende cyane, zishobora kwangiza ibice byubushakashatsi.Nyuma yo kwemeza ibyangiritse kurwego rwibigize, igerageza rirashobora kwirinda igihombo kidakenewe mbere.
