Mutsetse wekunonoka kwefiber optic wakavakirwa pakuchinja kwe optical

Nheyo yeFiber optic delay line

Mukugadzirisa masaini e-optical, fiber ye optical inogona kuona mabasa ekunonoka kwechiratidzo, kuwedzera, kupindira, nezvimwewo. Kushandiswa zvine musoro kwemabasa aya kunogona kuona mashandiro eruzivo mumunda we-optical. Pakati pawo, basa reDelay reFiber ye optical rinogona kugadzirwa kuita Fiber optic delay line, tichitora ordinary single-mode optical fiber semuenzaniso, kana kutumira kwewavelength yekushanda kwechiratidzo che optical ye1550nm, kutumira kwemamita mazana maviri kunogona kunonoka kwe1μs, uye kurasikirwa kwekuisa kunoenderana ne0.04dB chete. Mukuenzanisa, kurasikirwa kwekuisa kunokonzerwa nemutsara wekunonoka kwe microwave wetsika igumi nembiri ye dB, uye mutsara wekunonoka kwe fiber ye optical unoderedza kurasikirwa kwekuisa neanenge ma order maviri ehukuru, izvo zvinovandudza zvakanyanya kukwikwidza kwemutsara wekunonoka kwe Fiber optic. Pamusoro pezvo, Fibermutsetse wekunonoka kwemazisoine hunhu hwehukuru hudiki, huremu hwakareruka, chigadzirwa chebandwidth yekunonoka kukuru, kugona kwakasimba kwekudzivirira magineti, uye inova makwikwi akasimba emitsetse yekunonoka kwema microwave, uye inogona kutsiva zvachose mitsetse yekunonoka kwema microwave muminda yakawanda. Kana ichienzaniswa nemutsara wekunonoka kwema microwave wekare, mutsara wekunonoka kwema optical fiber une chigadzirwa chebandwidth yenguva refu, zvinoratidza kuti sisitimu ine resolution yakanaka yekuyera frequency, kunzwa kwakanyanya uye kugona kwekudzivirira masaini epamusoro, uye inogona kusangana nezvinodiwa zvemasisitimu eradar ekugadzirisa kwepamusoro senge mitsetse yekunonoka. Uye frequency yekushanda kweFDL yakakwira kwazvo, inogona kunge yakakwira kupfuura 100GHz, zvichienzaniswa nemutsara wekunonoka kwema wave wemazana e megahertz operating frequency uye CCD delay line yemakumi e megahertz operating frequency zvichienzaniswa nemirairo yakati wandei, uye zvichibva pane radar yekutaurirana yeramangwana nedzimwe masisitimu dzichachinja kuenda kune trend ye high frequency band, FDL ibhenefiti yakakosha; Pamusoro pezvo, mutsara wekunonoka kwema fiber une hunhu hwekuti kurasikirwa kwekunonoka kweyuniti hakuna kuzvimiririra pama frequency. Zvakanakira zvakasiyana zvemitsetse yekunonoka kwema fiber optic izvi pasina mubvunzo zvinoratidza kugona kwayo mukugadzirisa masaini.

Kushandiswa kweFiber optic delay line

Basa guru reFiber optic delay line nderekunonotsa chiratidzo, icho chinogona kuona basa rekuchengetedza kwese-optical uye shift equality nekushandisa delay, uye ine mashandisirwo akasiyana-siyana mu phased array radar, optical fiber communication system, optical computer system uye electronic countermeasures. Mu phased array radar, phased array antenna ndiyo chikamu chikuru, basa guru re phased array antenna nderekuchinja basa repattern ye synthesized beam, kuitira kuti pave nekuchinja kwechimiro cheantenna beam uye kukurumidza kuongorora beam, uye basa iri rinoitwa nekudzora amplitude uye phase information yesignal mu antenna unit, saka delay line chikamu chakakosha. Kana tichienzanisa ne microwave delay line, FDL ine bandwidth yakakura, uye hapana dambudziko re beam tilt. Mu optically controlled phased array antenna, FDL inogona kuona kugoverwa kwe phase uye kutonga kwe microwave signal uye kubvisa ruzha rwakabatana ne echo signal, saka FDL inogona kuva sarudzo yakanakisisa mu phased array antenna. Mu radar target simulator, FDL inoshandiswa kutevedzera masignals edaro dzakasiyana. Nekuda kwezvinodiwa zve radar system yemazuva ano ye radar target simulator, zvakaita se high frequency band, fast target switching speed uye long target simulation distance, traditional delay lines hadzina kuzadzisa zvinodiwa zve radar system, saka fiber optic delay line ndiyo chete yave iri delay line inoshanda. Kuwedzera pane zvataurwa pamusoro apa, mu optical fiber communication system, FDL inogonawo kuona basa re signal coding uye caching. Muchidimbu, zvinogona kuonekwa kuti fiber optic delay line ine mashandisirwo akakosha uye chinzvimbo chisingatsiviwi munzvimbo dzakawanda, saka kudzidza high-performance fiber optic delay line kune kukosha kukuru kwesainzi pakushandiswa kwetekinoroji ye microwave photon.

Dhizaini yemutsetse wekunonoka weFiber optic

Mutsetse wekunonoka kwefiber optic unobva pa optical switch unosarudza nzira dzakasiyana dze optical kuti uwane kunonoka kwenguva kwakasiyana kuburikidza ne optical switch. Nheyo huru yerudzi urwu rwechirongwa ndeyekuwana kunonoka kwakasiyana nekushandura nzira ye optical. Ndiwo mutsara we Fiber optic delay wakajairika, uye chimiro chawo chakajairika chinoratidzwa mumufananidzo.

 

Mushure mekunge chiratidzo che optical chakagadziriswa chatumirwa kuburikidza ne optical fiber, nzira ye optical inogadzira kunonoka kwakafanana inosarudzwa ne optical switch array, uye kunonoka kunodiwa kunogona kuwanikwa nekubatidza optical switch uye kuona kuti mamwe ma optical switches adzimwa. Kubatsira kwerudzi urwu rwe optical fiber delay line ndeyekuti inogona kuwana kunonoka kukuru, nzira yekuzadzisa iri nyore, uye hunhu hunoenderana hwakasiyana zvichienderana nesarudzo yema optical switches akasiyana.
