Kodi Fiber Optic Delay Line OFDL ndi chiyani

Fiber Optical Delay Line (OFDL) ndi chipangizo chomwe chimatha kukwaniritsa kuchedwa kwa nthawi ya ma siginecha a kuwala. Pogwiritsa ntchito kuchedwa, imatha kukwaniritsa kusintha kwa gawo, kusungirako zinthu zonse ndi ntchito zina. Ili ndi ntchito zosiyanasiyana mu radar yotsatizana, fiber optic communication systems, electronic countermeasures, kafukufuku wa sayansi ndi kuyesa, ndi zina. Nkhaniyi iyambira pa mfundo zazikuluzikulu za mizere yochedwa ya fiber optic, kuyang'ana kwambiri za momwe angagwiritsire ntchito komanso momwe mungasankhire mzere wochedwa wa fiber optic.
Mfundo yogwira ntchito
Mfundo yofunika kwambiri ya fiber optic yochedwa mzere ndi yakuti chizindikiro cha kuwala kuti chichedwetsedwe chimaperekedwa kudzera muutali wamtundu wa fiber optic chingwe, ndipo chifukwa cha nthawi yofunikira yowunikira mu chingwe cha fiber optic, kuchedwa kwa nthawi kwa chizindikiro cha kuwala kumatheka. Monga momwe tawonetsera pa Chithunzi 1, mzere wosavuta kwambiri wa fiber optic ndi dongosolo lopangidwa ndi zipangizo monga lasers, modulators, transmission fibers, ndi photodetectors ndi ntchito yochedwa chizindikiro. Mfundo yogwira ntchito: Chizindikiro cha RF chomwe chiyenera kufalitsidwa ndi chizindikiro cha kuwala chomwe chimatulutsidwa ndi laser chimalowetsedwa m'ma module osiyanasiyana. Ma modulators amawongolera siginecha ya RF pakuwala kuti apange chizindikiro chonyamula chidziwitso cha RF. Chizindikiro chonyamula chidziwitso cha RF chimaphatikizidwa ndi ulalo wa fiber optic kuti utumizidwe, kuchedwa kwakanthawi, kenako kukafika pa chojambula zithunzi. Photodetector imasintha chizindikiro cholandirira chonyamula chidziwitso cha RF kukhala chotulutsa magetsi.

Chithunzi 1 Zomangamanga Zoyambira za Optic Fiber Delay Line OFDL

Zochitika zantchito
1.Phased array radar: Chigawo chapakati cha radar yotsatizana ndi gawo la antenna. Nnyanga zachikhalidwe za radar zili kutali kuti zikwaniritse zofunikira zamakina a radar, pomwe mizere yochedwa ya fiber optic ili ndi maubwino ake apadera pakugwiritsa ntchito tinyanga ta magawo osiyanasiyana. Chifukwa chake, mizere yochedwa ya fiber optic imakhala ndi tanthauzo lasayansi mu radar yotsatizana.
2.Fiber optic communication system: Mizere yochedwa ya Fiber optic ingagwiritsidwe ntchito kukhazikitsa ndondomeko za encoding. Poyambitsa kuchedwa kosiyana pa nthawi zosiyanasiyana, ma encoding siginecha okhala ndi mawonekedwe apadera amatha kupangidwa, zomwe zimakhala zopindulitsa pakuwongolera kuthekera kotsutsana ndi kusokoneza kwa ma sign mumayendedwe olumikizirana a digito. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati chosungirako kwakanthawi (cache) kuti musunge kwakanthawi deta inayake, ndi zina zotero. Mwachidule, mizere yochedwa ya fiber optic imakhala ndi ntchito zambiri m'magawo ambiri chifukwa cha kuchuluka kwa bandwidth, kutayika kochepa, komanso kukana kusokoneza kwamagetsi. Kaya m'mayankhulidwe, ma radar, kuyenda panyanja, kapena kujambula zithunzi zachipatala, zonsezi zimagwira ntchito zofunika kwambiri.
