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 ifinyelele 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. Ngesikhathi esifanayo, 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.
