Bhalisela kwiMidiya yethu yeNtlalo ukuze ufumane iPosi ekhawulezileyo
Kwihlabathi elikhawulezayo lophuhliso lwetekhnoloji, ukusetyenziswa kweelaser kuye kwanda kakhulu, kwaguqula amashishini ngezicelo ezifana nokusika ilaser, ukuwelda, ukumakisha, kunye nokugquma. Nangona kunjalo, olu lwandiso lutyhile umsantsa omkhulu kulwazi lokhuseleko kunye noqeqesho phakathi kweenjineli kunye nabasebenzi bezobugcisa, nto leyo ebeka abasebenzi abaninzi abaphambili kwimitha yelaser ngaphandle kokuqonda iingozi ezinokubakho. Eli nqaku lijolise ekukhanyiseni ukubaluleka koqeqesho lokhuseleko lwelaser, imiphumo yebhayoloji yokuvezwa kwelaser, kunye namanyathelo okukhusela apheleleyo okukhusela abo basebenza ngetekhnoloji yelaser okanye ejikeleze.
Isidingo Esibalulekileyo Soqeqesho Lokhuseleko Lwelaser
Uqeqesho lokhuseleko lwelaser lubaluleke kakhulu kukhuseleko lokusebenza kunye nokusebenza kakuhle kwe-laser welding kunye nezinye izinto ezifanayo. Ukukhanya okunamandla kakhulu, ubushushu, kunye neegesi ezinokuba yingozi eziveliswa ngexesha lokusebenza kwelaser zibeka emngciphekweni impilo yabasebenzi. Uqeqesho lokhuseleko lufundisa iinjineli kunye nabasebenzi malunga nokusetyenziswa ngokuchanekileyo kwezixhobo zokuzikhusela (PPE), ezifana neeglasi zokukhusela kunye nezikhuselo zobuso, kunye namaqhinga okuphepha ukuvezwa ngokuthe ngqo okanye ngokungathanga ngqo kwelaser, ukuqinisekisa ukhuseleko olusebenzayo lwamehlo kunye nolusu lwabo.
Ukuqonda iingozi zeLaser
Iziphumo zebhayoloji zeLaser
Iilaser zinokubangela umonakalo omkhulu kulusu, nto leyo ebangela ukuba ulusu lukhuseleke. Nangona kunjalo, eyona ngxaki iphambili kukonakala kwamehlo. Ukuvezwa yilaser kunokukhokelela kwimiphumo yobushushu, i-acoustic, kunye ne-photochemical:
Ubushushu:Ukuveliswa kobushushu kunye nokufunxwa kunokubangela ukutsha kulusu namehlo.
I-Acoustic: Amaza omlilo anokubangela ukufuma kwindawo ethile kunye nomonakalo kwizicubu.
Ikhemikhali yefoto: Amaza athile obude belanga anokubangela ukusabela kweekhemikhali, okunokubangela i-cataracts, ukutsha kwe-cornea okanye i-retinal, kunye nokwandisa umngcipheko womhlaza wolusu.
Iziphumo zolusu zingaqala kubomvu obuncinci kunye nentlungu ukuya kutsho kwiqondo lesithathu lokutsha, kuxhomekeke kudidi lwelaser, ubude bentliziyo, izinga lokuphindaphinda, kunye nobude be-wavelength.
| Uluhlu lobude bamaza | Isiphumo sesifo |
| 180-315nm (UV-B, UV-C) | I-Photokeratitis ifana nokutsha lilanga, kodwa iyenzeka kwi-cornea yeliso. |
| 315-400nm(UV-A) | I-cataract ye-photochemical (ukufiphala kwelensi yeliso) |
| 400-780nm (Iyabonakala) | Umonakalo we-photochemical kwi-retina, okwaziwa ngokuba kukutsha kwe-retinal, kwenzeka xa i-retina yenzakele ngenxa yokukhanya. |
| 780-1400nm (Ekufutshane ne-IR) | I-Cataract, ukutsha kwe-retinal |
| 1.4-3.0μm(IR) | Ukuvutha kwamanzi (iproteni kwivumba lamanzi), i-cataract, ukutsha kwe-cornea Ukugqabhuka kwamanzi kuxa kuvela iproteni kwi-aqueous humor yeliso. I-cataract kukugquma kwelensi yeliso, kwaye ukutsha kwe-cornea kukonakalisa i-cornea, umphezulu wangaphambili weliso. |
| 3.0μm-1mm | Ukutsha kweComeal |
Umonakalo wamehlo, eyona nto iphambili, uyahluka ngokusekwe kubungakanani bomfundi, umbala, ubude bentliziyo, kunye nobude be-wavelength. Ii-wavelength ezahlukeneyo zingena kwiileya ezahlukeneyo zamehlo, zibangela umonakalo kwi-cornea, ilensi, okanye kwi-retina. Amandla okujolisa amehlo elisweni andisa kakhulu uxinano lwamandla kwi-retina, okwenza ukuba ukuvezwa komthamo ophantsi kwanele ukubangela umonakalo omkhulu kwi-retina, okukhokelela ekunciphiseni umbono okanye ubumfama.
Iingozi Zolusu
Ukuvezwa eluswini nge-laser kunokubangela ukutsha, amaqhakuva, amadyungudyungu, kunye notshintsho lombala, okunokutshabalalisa izicubu ezingaphantsi kolusu. Amaza ahlukeneyo angena kubunzulu obahlukeneyo kwizicubu zesikhumba.

Ulwahlulo lweeLaser eziyingozi
Iilaser zihlelwa ngokwengozi ezinokuba nayo emehlweni naselusu lomntu. Iilaser ezinamandla aphezulu zoshishino ezikhupha imitha engabonakaliyo (kuquka iilaser ze-semiconductor kunye neelaser ze-CO2) zibeka umngcipheko omkhulu. Imigangatho yokhuseleko ihlela zonke iinkqubo zelaser, kunyei-laser yefayibhaIziphumo zihlala zilinganiswa njengeKlasi yesi-4, nto leyo ebonisa inqanaba eliphezulu lomngcipheko. Kolu mxholo ulandelayo, siza kuxoxa ngokuhlelwa kokhuseleko lwelaser ukusuka kwiKlasi yoku-1 ukuya kwiKlasi yesi-4.
Imveliso yeLaser yeKlasi 1
Ilaser yeKlasi yoku-1 ithathwa njengekhuselekileyo ukuba wonke umntu ayisebenzise kwaye ayijonge kwiimeko eziqhelekileyo. Oku kuthetha ukuba awuyi kwenzakala ngokujonga ilaser enjalo ngokuthe ngqo okanye ngezixhobo eziqhelekileyo zokukhulisa ezifana neeteleskopu okanye iimakroskopu. Imigangatho yokhuseleko ijonga oku ngokusebenzisa imithetho ethile malunga nokuba indawo yokukhanya kwelaser inkulu kangakanani kwaye kufuneka ube kude kangakanani ukuze uyijonge ngokukhuselekileyo. Kodwa, kubalulekile ukwazi ukuba ezinye iilaser zeKlasi yoku-1 zisenokuba yingozi ukuba uzijonga ngeeglasi zokukhulisa ezinamandla kakhulu kuba ezi zinokuqokelela ukukhanya kwelaser okuninzi kunesiqhelo. Ngamanye amaxesha, iimveliso ezifana neeCD okanye iiDVD players ziphawulwa njengeKlasi yoku-1 kuba zinelaser enamandla ngaphakathi, kodwa yenziwe ngendlela yokuba akukho kukhanya kunobungozi okunokuphuma ngexesha lokusetyenziswa rhoqo.
