"cyclic fiber ring" ke eng?U tseba hakae ka eona?
Tlhaloso: Lesale la optical fiber leo ka lona leseli le ka potolohang hangata
Lesale la cyclic fiber ke asesebelisoa sa fiber opticeo kganya e ka potolohang ho ya pele le morao ka makgetlo a mangata.E sebelisoa haholo-holo tsamaisong e telele ea puisano ea fiber optical.Leha e le bolelele bo lekanyelitsoeng bafiber ea optical, leseli la pontšo le ka fetisoa libakeng tse telele haholo ka ho tsoelipana ka makhetlo a mangata.Sena se thusa ho ithuta liphello tse kotsi le optical nonlinearity tse amang boleng ba leseli la pontšo.
Ho theknoloji ea laser, li-loops tsa cyclic fiber li ka sebelisoa ho lekanya bophara ba mola oa alaser, haholo-holo ha bophara ba moeli bo le bonyenyane haholo (<1kHz).Ena ke katoloso ea mokhoa oa ho lekanya li-self-heterodyne linewidth, o sa hlokeng laser e eketsehileng ea ho fumana letšoao ho tsoa ho eona, e hlokang tšebeliso ea likhoele tse telele tsa mokhoa o le mong.Bothata ba thekenoloji ea ho lemoha ha heterodyne ke hore nako e hlokahalang ea nako ke ea tatellano e tšoanang le ea ho khutlisetsoa ha bophara ba mohala, e le hore bophara ba mohala bo be kHz tse seng kae feela, esita le ka tlase ho 1kHz e hloka bolelele bo boholo haholo ba fiber.
Setšoantšo sa 1: Setšoantšo sa schematic sa reng ea cyclic fiber.
Lebaka la mantlha la ho sebelisa li-fiber loops ke hore faeba e bolelele bo mahareng e ka fana ka tieho ea nako e telele hobane leseli le tsamaea ka makhetlo a mangata ka har'a fiber.E le ho arola leseli le fetisoang ka li-loops tse fapaneng, modulator ea acousto-optic e ka sebelisoa ho lupu ho hlahisa phetoho e itseng ea maqhubu (mohlala, 100MHz).Hobane phetoho ena ea maqhubu e kholo ho feta bophara ba mohala, leseli le tsamaileng ka mefuta e fapaneng ea lupu le ka aroloa sebakeng sa frequency.Hophotodetector, ea peleleseli la laserle ho otla ha lebone ka mor'a ho fetoha ha maqhubu ho ka sebelisoa ho lekanya bophara ba mohala.
Haeba ho se na sesebelisoa se holisang loop, tahlehelo ea modulator ea acousto-optic le fiber e kholo haholo, 'me matla a khanya a tla bola haholo ka mor'a loops tse' maloa.Sena se lekanyetsa haholo palo ea loops ha mola oa bophara o lekanngoa.Li-amplifiers tsa fiber li ka eketsoa ho loop ho felisa moeli ona.
Leha ho le joalo, sena se baka bothata bo bocha: le hoja leseli le fetang ka litsela tse fapaneng le arohane ka ho feletseng, lets'oao la ho otla le tsoa lipara tse fapaneng tsa photon, tse fetolang molumo oa ho otla ka kakaretso.Ring ea fiber ea optical e ka etsoa ka mokhoa o utloahalang ho thibela liphello tsena ka katleho.Qetellong, kutloisiso ea cyclic fiber loop e lekanyelitsoe ke lerata laamplifier ea fiber.Hape hoa hlokahala ho nahana ka ho se lumellane ha fiber le melapo e seng ea Lorentz ha ho etsoa data
