Ilebhu yelaserulwazi lokhuseleko
Kwiminyaka yakutshanje, ngophuhliso oluqhubekayo lweshishini le-laser,iteknoloji yelaseriye yaba yinxalenye engenakwahlulwa kwicandelo lophando lwesayensi, ishishini kunye nobomi. Kubantu abasebenzisa i-photoelectric ababandakanyeka kushishino lwe-laser, ukhuseleko lwe-laser lunxulumene kakhulu neelebhu, amashishini kunye nabantu ngabanye, kwaye ukuphepha ukwenzakaliswa yi-laser kubasebenzisi kuye kwaba yinto ephambili.
A. Inqanaba lokhuselekoileza
Iklasi 1
1. Udidi 1: Amandla eLaser < 0.5mW. ILaser ekhuselekileyo.
2. IKlasi 1M: Akukho monakalo ekusebenziseni okuqhelekileyo. Xa usebenzisa ii-optical observers ezifana neeteleskopu okanye iiglasi ezincinci zokukhulisa, kuya kubakho iingozi ezidlula umda weKlasi 1.
Iklasi yesi-2
1, Udidi 2: amandla elaser ≤1mW. Ukuvezwa kwangoko okungaphantsi kwe-0.25s kukhuselekile, kodwa ukuyijonga ixesha elide kunokuba yingozi.
2, iClass2M: kuphela kwiliso lenyama elingaphantsi kwe-0.25s, ukukhanyiswa kwemitha okukhawulezileyo kukhuselekile, xa kusetyenziswa iiteleskopu okanye iglasi encinci yokukhulisa kunye nomnye umjongi we-optical, kuya kubakho umonakalo ongaphezulu kwexabiso elimiselweyo leClass2.
Iklasi 3
1, iKlasi 3R: amandla elaser 1mW~5mW. Ukuba ibonwa okwethutyana nje, iliso lomntu liya kudlala indima ethile yokukhusela ekukhanyeni kokukhanya okukhuselekileyo, kodwa ukuba indawo yokukhanya ingena kwiliso lomntu xa ijongiwe, iya kubangela umonakalo kwiliso lomntu.
2, iKlasi 3B: amandla elaser 5mW ~ 500mW. Ukuba inokubangela umonakalo emehlweni xa ujonge ngqo okanye ubonakalisa, kukhuselekile ukubona ukubonakalisa okusasazekayo, kwaye kuyacetyiswa ukuba unxibe iiglasi zokukhusela ilaser xa usebenzisa eli nqanaba lelaser.
Iklasi yesi-4
Amandla elaser: > 500mW. Iyingozi emehlweni naselusu, kodwa ingonakalisa izinto ezikufutshane nelaser, ivuthe izinto ezitshayo, kwaye kufuneka unxibe iiglasi zelaser xa usebenzisa eli nqanaba lelaser.
B. Ukulimala kunye nokukhuselwa kwe-laser emehlweni
Amehlo lelona candelo lisengozini kakhulu kumalungu omzimba womntu kumonakalo we-laser. Ngaphezu koko, iziphumo zebhayoloji ze-laser zinokuqokelelana, nokuba ukuvezwa kube kanye akubangeli monakalo, kodwa ukuvezwa okuninzi kunokubangela umonakalo, amaxhoba okuvezwa ngokuphindaphindiweyo kwe-laser elisweni adla ngokuba nezikhalazo ezicacileyo, aziva kuphela ukwehla kancinci kancinci kombono.Isibane selaserIgubungela zonke ii-wavelengths ukusuka kwi-ultraviolet egqithisileyo ukuya kwi-infrared ekude. Iiglasi zokukhusela i-laser luhlobo lweeglasi ezikhethekileyo ezinokuthintela okanye zinciphise umonakalo we-laser kwiliso lomntu, kwaye zizixhobo ezibalulekileyo kwiimvavanyo ezahlukeneyo ze-laser.
C. Ungazikhetha njani izibuko ze-laser ezifanelekileyo?
1, khusela ibhendi yelaser
Qinisekisa ukuba ufuna ukukhusela ubude be-wavelength enye okanye ii-wavelength ezininzi ngaxeshanye. Uninzi lweeglasi zokukhusela nge-laser zinokukhusela ubude be-wavelength enye okanye ezingaphezulu ngaxeshanye, kwaye indibaniselwano eyahlukeneyo yee-wavelength inokukhetha iiglasi zokukhusela nge-laser ezahlukeneyo.
2, OD: uxinano lwe-optical (ixabiso lokukhusela i-laser), T: ukuhanjiswa kwebhendi yokukhusela
Iiglasi zokukhusela nge-laser zinokwahlulwa zibe ngamanqanaba e-OD1+ ukuya kwi-OD7+ ngokwenqanaba lokhuseleko (okukhona ixabiso le-OD liphezulu, kokukhona ukhuseleko luphezulu). Xa sikhetha, kufuneka sinikele ingqalelo kwixabiso le-OD eliboniswe kwisibini ngasinye seglasi, kwaye asinakutshintsha zonke iimveliso zokukhusela nge-laser ngelensi enye yokukhusela.
3, VLT: ukuhanjiswa kokukhanya okubonakalayo (ukukhanya okungqongileyo)
"Ukuhanjiswa kokukhanya okubonakalayo" kudla ngokuba yenye yeendlela ezithathwa lula xa kukhethwa iiglasi zokukhusela i-laser. Ngelixa kuvalwa i-laser, isibuko sokukhusela i-laser siya kuvala nenxalenye yokukhanya okubonakalayo, nto leyo echaphazela ukujongwa. Khetha ukuhanjiswa kokukhanya okubonakalayo okuphezulu (okufana ne-VLT> 50%) ukuze kube lula ukujongwa ngokuthe ngqo kweziganeko zovavanyo lwe-laser okanye ukucutshungulwa kwe-laser; Khetha ukuhanjiswa kokukhanya okubonakalayo okuphantsi, okufanelekileyo ekukhanyeni okubonakalayo, kodwa amaxesha anamandla kakhulu.
Qaphela: Iliso lomqhubi welaser alinakujoliswa ngqo kumqadi welaser okanye ekukhanyeni kwayo okubonakalayo, nokuba ukunxiba isibuko esikhuselayo selaser akunakujonga ngqo kumqadi (ujonge kwicala lokukhutshwa kwelaser).
D. Ezinye iindlela zokuzikhusela nokukhusela
Ukubonakaliswa kwelaser
1, xa besebenzisa i-laser, abavavanyi kufuneka basuse izinto ezineendawo ezikhanyayo (ezifana neewotshi, iiringi kunye neebheji, njl.njl., ziyimithombo enamandla yokukhanya) ukuze baphephe umonakalo obangelwa kukukhanya okukhanyayo.
2, ikhethini yelaser, i-light baffle, i-beam collector, njl.njl., inokuthintela ukusasazeka kwelaser kunye nokubonakaliswa okulahlekileyo. I-laser safety shield inokutywina i-laser beam ngaphakathi koluhlu oluthile, kwaye ilawule i-laser switch ngokusebenzisa i-laser safety shield ukuthintela umonakalo we-laser.
E. Ukubeka kunye nokujonga nge-laser
1, kwi-infrared, i-ultraviolet laser beam engabonakaliyo kwiliso lomntu, musa ukucinga ukuba ukungaphumeleli kwe-laser kunye nokujongwa kwamehlo, ukujongwa, ukubeka kunye nokuhlolwa kufuneka kusetyenziswe ikhadi lokubonisa le-infrared/ultraviolet okanye isixhobo sokujonga.
2, kwimveliso yefayibha edibeneyo yelaser, uvavanyo lwefayibha olubanjwe ngesandla, aluyi kuchaphazela kuphela iziphumo zovavanyo kunye nozinzo, indawo engafanelekanga okanye ukukrwela okubangelwa kukuhamba kwefayibha, indlela yokuphuma kwelaser ngaxeshanye itshintshiwe, kuya kuzisa nemingcipheko emikhulu yokhuseleko kubavavanyi. Ukusetyenziswa kwebracket yefayibha yokukhanya ukulungisa ifayibha yokukhanya akuphuculi nje kuphela uzinzo, kodwa kuqinisekisa ukhuseleko lovavanyo kakhulu.
F. Ziphephe iingozi kunye nokulahlekelwa
1. Akuvumelekanga ukubeka izinto ezinokutsha neziqhumayo kwindlela edlula kuyo i-laser.
2, amandla aphezulu e-laser e-pulsed aphezulu kakhulu, nto leyo enokubangela umonakalo kwiindawo zovavanyo. Emva kokuqinisekisa umda wokumelana nomonakalo kwiindawo, uvavanyo lunokuthintela ilahleko ezingeyomfuneko kwangaphambili.
