Chii chinonzi Fiber Optic Delay Line (OFDL)?

Chii chinonzi FiberMutsetse weKunonoka kweOpticOFDL

Fiber Optical Kunonoka Mutsetse(OFDL) chishandiso chinogona kunonoka nguva yezviratidzo zve optical. Nekushandisa delay, chinogona kunonoka kuchinja kwechikamu, kuchengetedza kwese kwe optical uye mamwe mabasa. Chine mashandisirwo akasiyana-siyana mu radar ye phased array, fiber optic communication systems, electronic countermeasures, study and testing yesainzi, nedzimwe nzvimbo. Chinyorwa chino chichatanga kubva pamisimboti yekutanga ye fiber optic delay lines, tichitarisa pane zviitiko zvekushandisa uye masarudzo akakodzera fiber optic delay line.
Musimboti wekushanda
Nheyo huru yemutsara wekunonoka kwefiber optic ndeyekuti chiratidzo che optical chinofanira kunonoka chinotumirwa kuburikidza nehurefu hwakatarwa hwetambo ye fiber optic, uye nekuda kwenguva inodiwa kuti chiedza chitumirwe mutambo ye fiber optic, kunonoka kwenguva kwechiratidzo che optical kunowanikwa. Sezvakaratidzwa muMufananidzo 1, mutsara wekunonoka kwefiber optic uri nyore isystem inoumbwa nemidziyo yakaita se lasers, modulators, transmission fibers, uye photodetectors ine basa rekunonoka kwechiratidzo. Nheyo yekushanda: RF signal inofanira kutumirwa uye chiratidzo che optical chinoburitswa ne laser zvinopinzwa muma modulators akasiyana-siyana. Ma modulators anogadzirisa RF signal pachiedza kuti agadzire chiratidzo che optical chinotakura ruzivo rweRF. Ruzivo rweRF runotakura chiratidzo che optical rwakabatanidzwa kune fiber optic link yekutumira, inononoka kwenguva yakati, uye yozosvika pamudziyo wekuona fotoChinoongorora chiedza chinoshandura chiratidzo chemagetsi chinogamuchira chinotakura ruzivo rweRF kuita chinobuda muchiratidzo chemagetsi.

Mufananidzo 1 Magadzirirwo Ekutanga eMutsetse weKunonoka kweFiber yeOpticOFDL

Mamiriro ekushandisa
1. Phased array radar: Chinhu chikuru che phased array radar iphased array antenna. Ma antenna echinyakare e radar haasi kusvika pazvinodiwa nema radar system, nepo fiber optic delay lines ane zvakanakira zvawo pakushanda mukushandisa ma phased array antennas. Saka, fiber optic delay lines ine kukosha kukuru kwesainzi mu phased array radar.
2. Sisitimu yekutaurirana neFiber optic: Mitsetse yekunonoka yeFiber optic inogona kushandiswa kuita zvirongwa zvekukodha zvakananga. Nekuunza kunonoka kwakasiyana panguva dzakasiyana, masaini ekodhi ane mapatani chaiwo anogona kugadzirwa, izvo zvinobatsira pakuvandudza kugona kwezviratidzo kudzivirira kupindirana mumasisitimu ekutaurirana edhijitari. Pamusoro pezvo, inogona zvakare kushandiswa senzvimbo yekuchengetera kwenguva pfupi (cache) yekuchengetedza kwenguva pfupi data, nezvimwewo. Muchidimbu, mitsetse yekunonoka yefiber optic ine mashandisirwo akasiyana-siyana muminda yakawanda nekuda kwebandwidth yavo yakawanda, kurasikirwa kushoma, uye kuramba kukanganiswa neelectromagnetic. Ingave iri muminda yekutaurirana, radar, navigation, kana medical imaging, ese anoita mabasa akakosha.
