Fiber yog dab tsiKab Ncua Kev Ncua OpticOFDL
Fiber Optical Delay Line(OFDL) yog ib lub cuab yeej uas tuaj yeem ua tiav lub sijhawm qeeb ntawm cov teeb liab optical. Los ntawm kev siv qeeb, nws tuaj yeem ua tiav theem hloov pauv, tag nrho-optical cia thiab lwm yam haujlwm. Nws muaj ntau yam kev siv hauv phased array radar, fiber optic kev sib txuas lus systems, hluav taws xob countermeasures, kev tshawb fawb thiab kev sim, thiab lwm yam teb. Tsab xov xwm no yuav pib los ntawm cov hauv paus ntsiab lus ntawm fiber optic qeeb kab, tsom mus rau cov xwm txheej daim ntawv thov thiab yuav ua li cas xaiv cov fiber optic qeeb kab tsim nyog.
Txoj cai ua haujlwm
Lub hauv paus ntsiab lus ntawm fiber optic qeeb kab yog tias lub teeb liab optical kom raug ncua yog xa mus los ntawm qhov ntev tshwj xeeb ntawm fiber optic cable, thiab vim yog lub sijhawm xav tau rau kev xa lub teeb hauv fiber optic cable, lub sijhawm ncua ntawm lub teeb liab optical tau ua tiav. Raws li pom hauv Daim Duab 1, qhov yooj yim tshaj plaws fiber optic qeeb kab yog ib lub kaw lus tsim los ntawm cov khoom siv xws li lasers, modulators, kis fibers, thiab photodetectors nrog lub teeb liab qeeb ua haujlwm. Lub hauv paus ntsiab lus ua haujlwm: Lub teeb liab RF kom raug xa mus thiab lub teeb liab optical tso tawm los ntawm laser yog nkag mus rau hauv ntau yam modulators. Cov modulators modulate lub teeb liab RF rau ntawm lub teeb los tsim lub teeb liab optical nqa cov ntaub ntawv RF. Lub teeb liab optical nqa cov ntaub ntawv RF yog txuas nrog lub fiber optic txuas rau kev xa, ncua rau ib lub sijhawm, thiab tom qab ntawd mus txoglub tshuab ntes duabLub photodetector hloov cov teeb liab optical uas tau txais uas nqa cov ntaub ntawv RF mus rau hauv cov teeb liab hluav taws xob.
Daim Duab 1 Cov Qauv Tsim Qauv Tseem Ceeb ntawmOptical Fiber Delay LineOFDL
Cov xwm txheej ntawm daim ntawv thov
1. Phased array radar: Lub hauv paus tseem ceeb ntawm phased array radar yog lub phased array antenna. Cov radar antennas ib txwm tsis tau ua raws li qhov yuav tsum tau ua ntawm radar systems, thaum cov kab fiber optic qeeb muaj lawv cov txiaj ntsig zoo hauv kev siv cov phased array antennas. Yog li ntawd, cov kab fiber optic qeeb muaj qhov tseem ceeb hauv kev tshawb fawb hauv phased array radar.
2. Lub kaw lus sib txuas lus fiber optic: Cov kab fiber optic qeeb tuaj yeem siv los ua cov qauv encoding tshwj xeeb. Los ntawm kev qhia txog kev ncua sijhawm sib txawv ntawm cov sijhawm sib txawv, encoding cov cim nrog cov qauv tshwj xeeb tuaj yeem tsim, uas yog qhov zoo rau kev txhim kho lub peev xwm tiv thaiv kev cuam tshuam ntawm cov cim hauv cov kab ke sib txuas lus digital. Tsis tas li ntawd, nws kuj tseem tuaj yeem siv ua qhov chaw khaws cia ib ntus (cache) los khaws qee cov ntaub ntawv ib ntus, thiab lwm yam. Hauv ntej, cov kab fiber optic qeeb muaj ntau yam kev siv hauv ntau qhov chaw vim lawv cov bandwidth siab, kev poob qis, thiab kev tiv thaiv electromagnetic cuam tshuam. Txawm hais tias nyob rau hauv cov teb ntawm kev sib txuas lus, radar, navigation, lossis kev kho mob duab, lawv txhua tus ua lub luag haujlwm tseem ceeb.
