Okushaama-photodetectorsukuguqula ukuxhumana kwe-fiber optical kanye nobuchwepheshe benzwa
Ngokuqhubeka okuqhubekayo kwesayensi nobuchwepheshe, izinhlelo zokuxhumana ze-fiber optical kanye nezinhlelo zokuzwa i-fiber optical zishintsha izimpilo zethu.Isicelo sabo singene kuzo zonke izici zempilo yansuku zonke, kusukela ekuxhumaneni kwe-inthanethi kuya ekuxilongweni kwezokwelapha, kusukela ezishintshayo zezimboni kuya ocwaningweni lwesayensi.Muva nje, uhlobo olusha lwei-photodetectoruguqule zombili izinhlelo.
Le photodetector ihlanganisa aI-PIN photodiodekanye nesekethe ye-amplifier yomsindo ephansi yomkhawulokudonsa wokusebenza ophezulu kanye nokulahlekelwa okuphansi kokufaka.Lokhu kusho ukuthi iyakwazi ukuthwebula isignali yokukhanya ngesikhathi esifushane kakhulu futhi iguqule ibe isignali kagesi, ngaleyo ndlela izuze ukuguqulwa kwe-photoelectric ngesivinini esiphezulu nokusebenza kahle.
Ukwengeza, ibanga le-wavelength le-photodetector limboza u-300nm kuya ku-2300nm, elimboza cishe wonke amaza abonakalayo nama-infrared wavelength.Lesi sakhiwo sikwenza kube lula ukuthi sisetshenziswe ezinhlobonhlobo zezinhlelo ezahlukene zokubona nezinzwa.
I-photodetector inokucubungula isignali ye-analog nemisebenzi yokukhulisa, engakhulisa amasignali okukhanya abuthakathaka ngokwanele ukuba atholwe ithuluzi ngesikhathi esifushane kakhulu.Lokhu kuvumela ukuthi idlale indima ebalulekile emikhakheni efana nokuxhumana kwe-optical, ukuhlaziywa kwe-spectral, i-lidar nokunye.
Ngaphezu kokuba namandla, lesi sithwebuli sezithombe sihlakaniphe kakhulu ekwakhiweni.Igobolondo lenzelwe ukuvimbela ukuphazamiseka kothuli kanye nozibuthe kagesi, okungavikela ngempumelelo isekethe yangaphakathi ekuphazamisekeni kwangaphandle.Ngasikhathi sinye, isikhombimsebenzisi sayo sokuphuma kwe-SMA senza kube lula ukuxhumana namanye amadivaysi.
Kuhle ukusho ukuthi igobolondo lalesi sithombe se-photodetector linembobo enentambo, ukuze ikwazi ukulungiswa endaweni yesikhulumi se-optical noma imishini yokuhlola, eyenza kakhulu umsebenzi wokuhlola.
Sekukonke, lesi sithwebuli sezithombe esisha sithuthukisa kakhulu izinhlelo zokuxhumana ze-fiber optical kanye nezinhlelo zokuzwa i-fiber optical.Umkhawulokudonsa ophezulu wokusebenza kanye nokulahlekelwa kokufaka okuphansi kunika amandla ukuguqulwa kwe-photoelectric ngesivinini esiphezulu nokusebenza kahle, futhi ububanzi be-wavelength ebanzi kanye nokuzuza okuphezulu kwenza kube lula ukuzivumelanisa nezimo ezihlukahlukene zohlelo lokusebenza.Idizayini enhle nokufakwa okulula kuthuthukisa kakhulu ukuzizwisa komsebenzisi.Ukwethulwa kwalesi sithwebuli sezithombe ngokungangabazeki kuzothuthukisa ukuthuthukiswa kokuxhumana kwe-fiber optical kanye nobuchwepheshe benzwa, okusiholela ezweni elisha lokukhanya.
