Fibre optique itinda kumurongo ishingiye kuri optique

Ihame rya fibre optique yo gutinda

Mugutunganya ibimenyetso byose-optique, fibre optique irashobora kumenya imikorere yo gutinza ibimenyetso, kwaguka, kwivanga, nibindi. Muri byo, imikorere yo Gutinda kwa Fibre optique irashobora gukorwa mumurongo wo gutinda wa Fibre optique, ugafata urugero rusanzwe rwa fibre optique nkurugero, mugihe ihererekanyabubasha rya signal ya optique ikora yumurambararo wa 1550nm, ihererekanyabubasha rya metero 200 rishobora kugera ku gutinda kwa 1μs, kandi igihombo cyoherekeza hamwe ni 0.04dB gusa. Mugereranije, igihombo cyo kwinjiza cyatewe numurongo gakondo wa microwave yatinze ni mirongo ya dB, kandi umurongo wo gutinda wa fibre optique ugabanya igihombo cyo kwinjiza hafi ya ordre 2 yubunini, ibyo bikaba bitezimbere cyane guhatanira umurongo wo gutinda kwa Fibre optique. Byongeye, Fibreumurongo wo gutindaufite kandi ibiranga ubunini buto, uburemere bworoheje, ibicuruzwa binini bitinda kwaguka, imbaraga zikomeye zo kurwanya anti-electromagnetic, kandi uhinduka umunywanyi ukomeye wumurongo utinda wa microwave, kandi urashobora gusimbuza burundu imirongo yatinze ya microwave mubice byinshi. Ugereranije n'umurongo gakondo wo gutinda kwa microwave, umurongo wo gutinda wa fibre optique ufite igihe kinini cyumurongo mugari, ibyo bikaba byerekana ko sisitemu ifite igisubizo cyiza cyo gupima inshuro nyinshi, sensibilité yo hejuru hamwe nubushobozi bwo gufata ibimenyetso byinshi, kandi ishobora kuzuza ibisabwa na sisitemu ya radar ihanitse cyane nkumurongo utinda. Kandi imikorere ya FDL ni ndende cyane, irashobora kuba hejuru ya 100GHz, ugereranije nubuso bwa acoustic wave itinda kumurongo wa megahertz amajana n'amajana ikora hamwe na CCD itinda kumurongo wa megahertz inshuro icumi ugereranije na ordre nyinshi z'ubunini, kandi ukurikije radar y'itumanaho rizaza hamwe nubundi buryo bizahinduka mubyerekezo byumurongo mwinshi, FDL ninyungu zikomeye; Mubyongeyeho, umurongo wo gutinda kwa fibre nawo ufite ibiranga ko igihombo cyo gutinda cyigenga kidashingiye kuri frequence. Ibyiza bidasanzwe byiyi fibre optique itinda ntagushidikanya kwerekana ubushobozi bwayo mugutunganya ibimenyetso.

Gukoresha Fibre optique itinda kumurongo

Igikorwa cyibanze cya Fibre optique yo gutinza umurongo ni ugutinza ibimenyetso, bishobora kumenya imikorere yububiko bwose bwa optique hamwe nuburinganire bwimikorere ukoresheje gutinda, kandi ikaba ifite uburyo bwinshi bwimikorere mugice cya radar icyiciro, sisitemu yo gutumanaho ya fibre optique, sisitemu ya mudasobwa optique hamwe nuburyo bwo guhangana na elegitoronike. Mu cyiciro cya array radar, icyiciro cya array antenne nikintu cyibanze, umurimo wingenzi wa antenne yicyiciro cyicyiciro ni uguhindura imikorere yimikorere ya beam synthesize, kugirango rero ugere kumihindagurikire yimiterere ya antenna no gusikana byihuse kumurongo, kandi iyi mikorere igerwaho mugucunga amplitude hamwe nicyiciro cyamakuru yikimenyetso mubice bya antenne, bityo umurongo wo gutinda nigice cyingenzi. Ugereranije na microwave itinda kumurongo, FDL ifite umurongo munini, kandi ntakibazo cyo kugoreka. Muri antenne igenzurwa neza, FDL irashobora kumenya neza itangwa ryicyiciro no kugenzura ibimenyetso bya microwave no gukuraho urusaku rujyanye nibimenyetso bya echo, bityo FDL irashobora guhitamo neza muri antenne yicyiciro. Muri radar intego yigana, FDL ikoreshwa mukwigana ibimenyetso byintera zitandukanye. Hamwe nibisabwa bya sisitemu ya radar igezweho kubigana simusiga ya radar, nkumuvuduko mwinshi wa bande, umuvuduko wihuse wihuta hamwe nintera ndende yo kwigana, imirongo gakondo yo gutinda yabaye kure yujuje ibisabwa na sisitemu ya radar, bityo umurongo wo gutinda wa fibre optique wabaye umurongo wonyine wo gutinda. Usibye hejuru yavuzwe haruguru, muri sisitemu yo gutumanaho ya fibre optique, FDL irashobora kandi kumenya imikorere ya code code na cishing. Muncamake, birashobora kugaragara ko umurongo wa fibre optique itinda bifite akamaro gakomeye hamwe numwanya udasimburwa mubice byinshi, bityo rero ubushakashatsi bwibikorwa byo hejuru bya fibre optique itinda bifite akamaro gakomeye mubumenyi mugukoreshatekinoroji ya microwave.

Igishushanyo cya Fibre optique yo gutinda

Fibre optique itinda kumurongo ishingiye kuri optique ihitamo inzira zitandukanye kugirango igere kubihe bitandukanye bitinze binyuze muri optique. Ihame ryibanze ryubwoko nkubu ni ukugera kubukererwe butandukanye uhindura inzira nziza. Nibisanzwe bitandukanya Fibre optique itinda, kandi imiterere yabyo irerekanwa mumashusho.

 

Nyuma yuko ibimenyetso byahinduwe byahinduwe binyuze muri fibre optique, inzira ya optique itanga ubukererwe ijyanye na optique ya optique, kandi gutinda gusabwa kugerwaho mugukingura optique no kwemeza ko ubundi buryo bwa optique bwazimye. Ibyiza byubwoko bwa optique ya fibre itinda ni uko ishobora kugera kubukererwe bunini, uburyo bwo kubimenya buroroshye, kandi ibiranga bihuye biratandukanye ukurikije guhitamo kwa optique zitandukanye.
