Ilabhorethri ye-Laserulwazi lokuphepha
Eminyakeni yamuva nje, ngokuthuthuka okuqhubekayo kwemboni ye-laser,ubuchwepheshe be-laserisibe yingxenye engenakuhlukaniswa yenkundla yocwaningo lwesayensi, imboni kanye nempilo. Kubantu abathwebula ugesi ababambe iqhaza embonini ye-laser, ukuphepha kwe-laser kuhlobene eduze nezindawo zokucwaninga, amabhizinisi kanye nabantu ngabanye, futhi ukugwema ukulimala kwe-laser kubasebenzisi sekuyinto ehamba phambili.
A. Izinga lokuphepha lelaser
Ikilasi1
1. I-Class1: Amandla e-laser <0.5mW. I-laser ephephile.
2. I-Class1M: Akukho bungozi ekusebenziseni okuvamile. Uma usebenzisa izibukeli zamehlo ezinjengezibonakude noma izibuko ezincane zokukhulisa, kuzoba nezingozi ezeqa umkhawulo we-Class1.
Ikilasi2
1, I-Class2: amandla e-laser ≤1mW. Ukuchayeka ngokushesha okungaphansi kuka-0.25s kuphephile, kodwa ukukubuka isikhathi eside kungaba yingozi.
2, I-Class2M: kuphela ngeso lenyama elingaphansi kuka-0.25s imisebe esheshayo iphephile, lapho ukusetshenziswa kwetheleskopu noma ingilazi yokukhulisa izingane kanye nezinye izibukeli ezibonakalayo, kuzoba nenani elingaphezu komkhawulo we-Class2 lokulimala.
Ikilasi3
1, I-Class3R: amandla e-laser 1mW~5mW. Uma libonakala isikhathi esifushane kuphela, iso lomuntu lizodlala indima ethile yokuvikela ekuboniseni ukukhanya okuvikelayo, kodwa uma indawo yokukhanya ingena esweni lomuntu lapho igxilile, izodala umonakalo esweni lomuntu.
2, I-Class3B: amandla e-laser 5mW~500mW. Uma kungase kubangele ukulimala kwamehlo lapho ubuka ngokuqondile noma ubonisa, ngokuvamile kuphephile ukubona ukubonakaliswa okusabalalisayo, futhi kuyanconywa ukuthi ugqoke izibuko ezivikela i-laser lapho usebenzisa leli zinga le-laser.
Ikilasi4
Amandla e-Laser: > 500mW. Iyingozi emehlweni nasesikhumbeni, kodwa futhi ingalimaza izinto ezisetshenziswa eduze kwelaser, ithungele izinto ezivuthayo, futhi idinge ukufaka izibuko ze-laser uma usebenzisa leli zinga le-laser.
B. Ukulimala nokuvikelwa kwe-laser emehlweni
Amehlo ayingxenye esengozini kakhulu yesitho somuntu ekulimaleni kwe-laser. Ngaphezu kwalokho, imiphumela yebhayoloji ye-laser inganqwabelana, ngisho noma ukuvezwa okukodwa kungadali monakalo, kodwa ukuchayeka kaningi kungase kubangele umonakalo, izisulu zokuchayeka nge-laser okuphindaphindiwe esweni ngokuvamile azikho izikhalazo ezisobala, kuphela ukuzwa ukwehla kancane kancane kombono.Ukukhanya kwe-laserimboza wonke amaza amaza ukusuka emisebeni ye-ultraviolet eyeqisayo kuye kwe-infrared ekude. Izibuko zokuvikela i-laser ziwuhlobo lwezibuko ezikhethekile ezingavimbela noma zinciphise ukulimala kwe-laser esweni lomuntu, futhi zingamathuluzi ayisisekelo abalulekile ekuhlolweni kwe-laser okuhlukahlukene.
C. Ungakhetha kanjani izibuko ze-laser ezifanele?
1, vikela i-laser band
Nquma ukuthi ufuna ukuvikela ubude beza obubodwa noma amaza amaza amaningana ngesikhathi esisodwa. Izibuko eziningi ezivikelayo ze-laser zingavikela ubude beza beza obubodwa noma ngaphezulu ngesikhathi esisodwa, futhi inhlanganisela yamaza ehlukene ehlukene ingakhetha izibuko ezivikela i-laser.
2, OD: ukuminyana kokubona (inani lokuvikela i-laser), T: ukudluliselwa kwebhendi yokuvikela
Izibuko ezivikela i-laser zingahlukaniswa zibe amazinga e-OD1+ kuye ku-OD7+ ngokuya ngeleveli yokuvikela (uma inani le-OD liphakeme, ukuvikeleka kuphezulu). Lapho sikhetha, kufanele sinake inani le-OD elikhonjiswe kupheya ngayinye yezibuko, futhi asikwazi ukufaka ilensi eyodwa yokuvikela esikhundleni sayo yonke imikhiqizo yokuvikela nge-laser.
3, VLT: ukukhanya okubonakalayo okudluliswayo (ukukhanya okuzungezile)
"Ukudluliswa kokukhanya okubonakalayo" kuvame ukuba ngenye yemingcele enganakwa kalula uma kukhethwa izibuko ezivikela i-laser. Ngenkathi ivimbela i-laser, isibuko sokuzivikela se-laser sizophinde sivimbe ingxenye yokukhanya okubonakalayo, okuthinta ukubhekwa. Khetha ukudluliswa kokukhanya okuphezulu okubonakalayo (okufana ne-VLT>50%) ukuze kube lula ukubhekwa okuqondile kwezenzakalo zokuhlola i-laser noma ukucutshungulwa kwe-laser; Khetha ukudluliswa kokukhanya okuphansi okubonakalayo, okulungele ukukhanya okubonakalayo yizikhathi eziqine kakhulu.
Qaphela: Iso lika-opharetha we-laser alikwazi ukuqondiswa ngokuqondile ku-laser beam noma ukukhanya kwayo okubonisiwe, noma ngabe ukugqoka isibuko se-laser esivikelayo kungakwazi ukubheka ngqo epulangeni (ibheke lapho kuphuma khona i-laser).
D. Ezinye izinyathelo zokuphepha nokuvikela
I-laser reflection
1, uma kusetshenziswa i-laser, abahloli kufanele basuse izinto ezinezindawo ezikhanyayo (njengamawashi, izindandatho namabheji, njll., imithombo yokubonakalisa enamandla) ukuze kugwenywe umonakalo odalwe ukukhanya okubonisiwe.
2, ikhethini le-laser, i-baffle ekhanyayo, umqoqi we-beam, njll., ingavimbela ukusabalalisa kwe-laser kanye nokubonakala okulahlekile. Isihlangu sokuphepha se-laser singavala i-laser beam phakathi kwebanga elithile, futhi silawule iswishi ye-laser ngesihlangu sokuphepha se-laser ukuvikela ukulimala kwe-laser.
E. Laser positioning and observation
1, ku-infrared, i-ultraviolet laser beam engabonakali ngeso lomuntu, ungacabangi ukuthi ukwehluleka kwe-laser nokubheka iso, ukuqaphela, ukuma nokuhlola kufanele kusebenzise ikhadi lokubonisa infrared/ultraviolet noma ithuluzi lokubuka.
2, ngokukhipha okuhlanganisiwe kwefayibha ye-laser, ukuhlolwa kwefayibha ebanjwe ngesandla, ngeke nje kuthinte imiphumela yokuhlola nokuzinza, ukubekwa okungalungile noma ukuklwebheka okubangelwa ukususwa kwefayibha, isiqondiso sokuphuma kwe-laser ngesikhathi esifanayo esiguquliwe, futhi kuzoletha okuhle kakhulu. ubungozi bokuphepha kwabahloli. Ukusetshenziswa kwe-fiber optical bracket ukulungisa i-fiber optical akugcini nje ukuthuthukisa ukuzinza, kodwa futhi kuqinisekisa ukuphepha kokuhlolwa ngezinga elikhulu.
F. Gwema ingozi nokulahlekelwa
1. Akuvunyelwe ukubeka izinto ezivuthayo neziqhuma endleleni lapho i-laser idlula khona.
2, amandla aphezulu we-laser pulsed aphezulu kakhulu, angabangela ukulimala ezingxenyeni zokuhlola. Ngemva kokuqinisekisa umkhawulo wokumelana nomonakalo wezingxenye, ukuhlolwa kungagwema ukulahlekelwa okungadingekile kusengaphambili.
