Fiber Optic Delay Line OFDL yog dab tsi
Fiber Optical Delay Line (OFDL) yog ib qho khoom siv uas tuaj yeem ua tiav lub sijhawm ncua ntawm cov teeb liab kho qhov muag. 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 nyob rau hauv phased array radar, fiber optic kev sib txuas lus systems, hluav taws xob countermeasures, scientific research and testing, and other fields. Kab lus no yuav pib los ntawm cov hauv paus ntsiab lus ntawm fiber optic ncua kab, tsom mus rau daim ntawv thov scenarios thiab yuav ua li cas xaiv qhov tsim nyog fiber optic ncua kab.
Txoj cai ua haujlwm
Lub hauv paus ntsiab lus ntawm fiber optic ncua kab yog hais tias lub teeb liab kho qhov muag yuav ncua yog kis tau los ntawm ib tug ntev ntev ntawm fiber optic cable, thiab vim lub sij hawm yuav tsum tau rau lub teeb kis tau tus mob nyob rau hauv lub fiber optic cable, lub sij hawm ncua ntawm lub optical teeb liab yog tiav. Raws li pom nyob rau hauv daim duab 1, qhov yooj yim tshaj plaws fiber optic ncua kab yog ib qho system uas muaj xws li lasers, modulators, kis fibers, thiab photodetectors nrog lub teeb liab ncua kev ua haujlwm. Lub hauv paus ntsiab lus ua haujlwm: RF teeb liab yuav tsum tau xa mus thiab cov teeb liab kho qhov muag tawm los ntawm lub laser yog input rau hauv ntau yam modulators. Cov modulators modulate RF teeb liab mus rau lub teeb los tsim cov teeb liab kho qhov muag nqa RF cov ntaub ntawv. Lub teeb liab kho qhov muag nqa RF cov ntaub ntawv txuas mus rau fiber ntau optic txuas rau kev sib kis, ncua sij hawm ib ntus, thiab tom qab ntawd mus txog lub photodetector. Lub photodetector hloov pauv qhov tau txais cov teeb liab kho qhov muag nqa cov ntaub ntawv RF rau hauv cov teeb liab hluav taws xob tso tawm.
Daim duab 1 Basic Architecture ntawm Optic Fiber Delay Line OFDL
Daim ntawv thov scenarios
1.Phased array radar: Cov khoom tseem ceeb ntawm phased array radar yog lub kav hlau txais xov phased array. Tsoos radar kav hlau txais xov nyob deb ntawm kev ua tau raws li qhov yuav tsum tau ua ntawm radar systems, thaum fiber optic ncua kab muaj lawv qhov kev ua tau zoo tshwj xeeb hauv kev siv cov kav hlau txais xov phased array. Yog li ntawd, cov kab fiber ntau optic ncua sij hawm muaj qhov tseem ceeb ntawm kev tshawb fawb hauv cov theem array radar.
2.Fiber optic kev sib txuas lus: Fiber optic ncua kab tuaj yeem siv los ua cov phiaj xwm tshwj xeeb encoding. Los ntawm kev qhia txog kev ncua sij hawm sib txawv ntawm cov ntsiab lus sib txawv, cov cim encoding nrog cov qauv tshwj xeeb tuaj yeem tsim tawm, uas yog qhov zoo rau kev txhim kho kev tiv thaiv kev cuam tshuam ntawm cov teeb liab hauv kev sib txuas lus digital. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua ib ntus cia (cache) khaws cia qee cov ntaub ntawv ib ntus, thiab lwm yam. Nyob rau hauv luv luv, fiber optic ncua sij hawm kab muaj ntau yam kev siv nyob rau hauv ntau lub teb vim lawv siab bandwidth, tsawg poob, thiab tsis kam mus rau electromagnetic cuam tshuam. Txawm hais tias hauv kev sib txuas lus, radar, navigation, lossis kev kho mob, lawv txhua tus ua lub luag haujlwm tseem ceeb.
