Sei varimasisitimu e-fiber optic ane simba guruzviri nyore kuwana migumisiro isiri yemutsara?
In masisitimu e fiber optic, matambudziko mazhinji haamboitiki kana simba rakaderera, asi kana simba rawedzerwa, anongoerekana aonekwa kana kutotadza kudzorwa, akadai sekuwedzera kwespectral, kusagadzikana kwesimba, kukanganiswa kwemasaini, uye kudzikira kwekushanda zvakanaka kwesystem. Izvi zvinowanzo konzerwa neshoko guru: mhedzisiro isiri yemutsara. Saka mubvunzo ndewokuti: sei kana yangopinda mumamiriro esimba rakawanda, masisitimu e fiber optic anowanzo kuve nematambudziko asiri emutsara?
1, Zvikonzero zvakakosha zvemigumisiro isiri yemutsara
Zvinhu zve fiber optic (quartz) pachazvo zvine hunhu husina kurongeka, hunonyanya kuratidzwa se refractive index inochinja nekusimba kwechiedza (Kerr effect). Pasimba diki, mhedzisiro iyi haina kusimba zvakanyanya uye haina kukosha; Asi kana simba rawedzerwa, simba rechiedza rinowedzera uye mhedzisiro isiri yero inowedzerwa zvakanyanya.
2, Zvinhu zvikuru zvekuwedzera migumisiro isina kurongeka pasi pesimba guru
Kupenya kwakanyanya: Nzvimbo yemode field ye optical fibers idiki kwazvo (kazhinji makumi e μ m²), uye kunyangwe simba rese risiri rakakwirira, kupenya kwacho kwatove kwakakwira zvakanyanya. Migumisiro isiri yemutsara ine chekuita zvakananga nekupenya kwechiedza (pane simba rese), uye sezvo simba richiwedzera, kupenya kwechiedza kunowedzera nekukurumidza, uye mhedzisiro isiri yemutsara inowedzera zvinoenderana.
Kureba kwenguva yekushanda: Chiedza chiri mufiber ye optical chinogona kupararira kwemamita akati wandei kusvika makiromita akati wandei, uye mhedzisiro isiri yemutsara inoramba ichiungana mukati mekuita kwese kwekupararira, zvichizopedzisira zvave nemhedzisiro yakakosha. Kusimba kwemhedzisiro isiri yemutsara kunogona kunzwisiswa sekuenderana nekusimba kwechiedza kwakawedzerwa nehurefu hwekupararira.
3, Migumisiro Isingawanzoitiki uye Kuratidzwa Kwayo
Kuchinja kwechikamu chega chega (SPM): Kuchinja kwesimba rechiedza kunokonzera shanduko mu refractive index, zvichikonzera shanduko dzechikamu uye kuwedzera kwespectral, zvinoonekwa sekuwedzera kwepulse uye kuwedzera kwespectral.
Kupararira kweBrillouin Kunosundwa (SBS): Kunosundwa zviri nyore kana paine hupamhi hwakamanikana uye simba rakawanda, paine chiyero chakajeka chinogona kukonzera kupararira shure, kudzikamisa simba rinotumirwa, uye kukonzera kudzikira kamwe kamwe kana kusagadzikana mukubuda kwesystem.
Kupararira kweRaman kwakasimbiswa (SRS): Kunoonekwa musimba guru kana kuti mufiber refu, rinoratidzwa nekufambisa simba kuenda kumarefu ehurefu hwemafungu uye shanduko muchimiro chespectral.
4. Chikonzero nei dambudziko risingaonekwe pasi pesimba rakaderera
Migumisiro isina kurongeka ine hunhu hwepakati uye hunhu hwekukura kusiri kwepakati. Mhedzisiro yacho haina kusimba zvakanyanya uye yakaoma kuiunganidza nesimba diki; Kana simba rapfuura chiyero, mhedzisiro yacho inokurumidza kuwedzera uye inongoerekana yaonekwa, izvo zvinotsanangura chiitiko che "matambudziko anoonekwa kamwe kamwe simba parinokwira" muinjiniya.
5, Kupesana kukuru uye nzira dzekugadzirisa matambudziko muinjiniya
Masisitimu ane simba guru anofanirwa kudzvinyirira mhedzisiro isiri yemutsara uku achiwedzera simba. Nzira dzakajairika dzeinjiniya dzinosanganisira:
Kuwedzera nzvimbo yemunda wemode kuderedza simba rechiedza
Pfupisa hurefu hwechiito chinoshanda
Wedzera upamhi hwemutsetse kuti udzivise SBS
Gadzirisa magadzirirwo ehurongwa
Pfungwa huru ndeyekuderedza simba rechiedza pahuwandu hweyuniti kana kuderedza mhedzisiro yekuunganidza isiri yemutsara.
Mhedziso
Simba gurufiber opticMasisitimu anowanzo kuve nemigumisiro isiri yemutsara, uye chikonzero chikuru ndechekuti simba rechiedza chakawanda uye daro refu rekushanda mufaibha zvinowedzera hunhu husiri hwemutsara hwechinhu chacho. Migumisiro isiri yemutsara inoungana nesimba uye kureba, uye inokurumidza kuoneka mushure mekupfuura chiyero. Naizvozvo, kudzora simba rechiedza uye kureba kunoshanda mukugadzira sisitimu ndiyo kiyi yekudzvinyirira kusagadzikana.
