Yintoni i-fiber optic polilization?
Ingcaciso: Isixhobo esinokulawula imeko yokugcwala kokukhanya kwiintsinga. EzininziIzixhobo zeFiber Optic, njengabadlelane, bafuna ukukwazi ukulawula imeko yokulinganisa yokukhanya kwifibre. Ke ngoko, iintlobo ezahlukeneyo zee-fiber zothutho lwe-fiber polick ziphuhlisiwe.
Umlawuli wendlebe we-bat kwi-fiber fiber
Eqhelekileyoumlawuli wepaliifezekisiwe ngokugoba (okanye umoya) fibers off ukufumana i-birsfricringEnce. Ixabiso elipheleleyo lokulibazisa (ubungakanani be-birefricring) luhambelana nobude befibre kwaye ngokulinganayo ngokuhambelana neradiyo. Ikwanxulumene nohlobo lwefibre yefibre. Ngamanye amaxesha, i-fiber eyakhiweyo inokubangela amaxesha amaninzi nge-radius radius ukufumana ukulibaziseka kwe-λ / 2 okanye λ / 4.

Umzobo 1: I-BATAR YABELAR YABHIRLYORY PROLALALAYO, equlatha ii-fiber ezintathu zefible optic ezinokujikeleza kwi-Axiber yeFiber esedeni.
Ngokwesiqhelo, zisetyenziselwa ukwenza iikholamu ezintathu, kunye ne-coil ephakathi njengeplani ye-wave kunye namacala amabini njengekota yekota. I-Coil nganye inokujikeleza ecaleni kwe-axis yesiganeko kunye neentsinga eziphumayo. Ngokuhlengahlengiswa koqhelwaniso lweekholeji ezintathu, imeko yokulinganisa ye-polingth yesazisi inokuguqulwa ibe nayiphi na imeko yemeko yokukhupha. Nangona kunjalo, ifuthe kwipalifazation ikwanxulumene ne-wavelength. Kumandla aphezulu encopho (ihlala yenzeka e-Ultra itrace), ukujikeleza kokungcola kwe-nonline kwenzeka. Ububanzi be-fiber optic coin ayinakuba mncinci kakhulu, ngenye indlela ukugoba kuyakufika ilahleko eyongezelelweyo. Olunye uhlobo lwe-compact, kwaye lubuthathaka olungaphantsi kwe-nonlicarity, lusebenzisa i-BireFringEince eyomeleleyo (ulondolozo lwendalo) lweentsinga ze-fiber endaweni ye-fiber.
IcinezelweI-fiber polilation isilawuli
Kukho isixhobo esinokufumana iiplati zokutshintsha, ezinokuthi zicinezele ubude beentsinga ezithile ukuya kwinqanaba elithile phantsi koxinzelelo. Ngokuthe ngcembe ukujikeleza kunye nokucinezela i-fiber eyakhiweyo ngeenxa zonke kwi-axis yayo, kwaye iyibethe kumgama othile ukusuka kwicandelo elithile ukusuka kwicandelo loxinzelelo, nayiphi na into enokuthi ifunyanwe yimeko yokulinganisa inokufunyanwa. Ngapha koko, ukusebenza okufanayo njenge-babinet ogudileyo (uhlobo lwesininziisixhobo sokukhanyaEqulethe imiphetho emibini yebhanti) inokufunyanwa, nangona imigaqo yawo yokusebenza yahlukile. Izikhundla zoxinzelelo ezininzi zinokusetyenziswa, apho kuphela ingcinezelo, hayi i-angle yokujikeleza, utshintsho. Utshintsho loxinzelelo luhlala luphunyezwa kusetyenziswa abathengisi beePiezoeelelelelelelelelelelelelectric. Esi sixhobo sinokusebenza njengomlinganiso, apho i-Piezoeecturitric iqhutywa zii-frequents ezahlukeneyo okanye imiqondiso engaqhelekanga.
