Isingeniso kuI-PhotoDet ye-Balance(I-Optoelectronic Balance Detector)
I-Balance PhotoDeter ingahlukaniswa ngohlobo lwe-Fiber Optic Coupling nohlobo lwe-Spatial Optical Coupling ngokuya ngendlela yokuhlanganisa yokuhlanganisa. Ngaphakathi, iqukethe ama-PhotoDodios amabili ahambisana kakhulu, umsindo ophansi, umkhawulokudonsa we-bandwidth transpacance amplifier module, kanye nemodyuli yamandla e-ULTRA-Low Noise. Inezici zemodi ephezulu yesabelo sesabelo, umsindo ophansi we-Ultra, kanye nomkhawulokudonsa ophakeme, futhi isetshenziswa kabanzi emkhakheni wokuxhumana okubumbene kokuqonda. Sekuphenduke i-hotspot ecwaningayo yamabhizinisi namanyuvesi emazweni ahlukahlukene eminyakeni yamuva.
Ukusebenza komgomo we-PhotoDeteCom (I-OptoElectronic Balance Detector)
I-Basup PhotoDector isebenzisa ama-PhotoDodes amabili e-Reverse Bias State njengophiko lokuthola ukukhanya. Lapho uthola isiginali yokukhanya, i-PhotoCompent ekhiqizwa ama-PhotoDodiones amabili akhishwe futhi ahlanganiswe kwi-amplifier yokudlulisela ukuguqula isiginali yamanje ibe isibonakaliso se-voltage sokukhipha. Ukusetshenziswa kwesakhiwo esisezingeni eliphezulu kungacindezela ngempumelelo isibonakaliso semodi ejwayelekile eyethulwe ukukhanya kwe-Oscillator yasendaweni kanye namanje, kwandise isibonakaliso semodi ehlukile, futhi ngezinga elithile kuthuthukisa amandla okuthola amasiginali abuthakathaka.
Izinzuzo: Isilinganiso esiphakeme kakhulu sokwenqatshwa kwesabelo, ukuzwela okuphezulu, kanye ne-bandwidth ephezulu yokutholwa kungahlangabezana nezimo ezahlukahlukene zohlelo lokusebenza.
Okubi: Amandla aphezulu agcwele ama-optical, alungele ukutholwa okukhanyayo okubuthakathaka, ukuhlanganiswa kudinga ukwenziwa ngcono.
Umdwebo: Ukusebenza komqondo osebenza komshini wokulinganisa
Amapharamitha okusebenza e-PhotoDetetor (OptoelectronicUmtshina wokulinganisa)
1. Ukuphendula
Ukuphendula kusho ukusebenza kahle kwe-PhotoDiode ekuguquleni amasiginali akhanyayo ku-PhotoCoprent, okuyisilinganiso se-PhotoCoprent ukukhanyisa amandla. Ukukhetha i-Photodiode ngokuphendula okuphezulu kungathuthukisa ngempumelelo ukuzwela kwe-PhotoDetor esele.

2. Bandwidth
I-bandwidth imele imvamisa yesiginali lapho okuphuma khona kokukhishwa kwesiginali se-PhotoDector nge -3DB, futhi kuhlobene nokukhonkotha kwe-parasitic, futhi kuhlobene nokukhokhwa kwe-photodiade, kanye nomkhiqizo we-bandwidth we-amplifier yokusebenza.
I-3. Imodi ejwayelekile yenqatshwa isilinganiso
I-Common Mediction Ukwenqaba Isilinganiso isetshenziselwa ukukala izinga lokucindezelwa kwezimpawu ezijwayelekile zemodi ngemishini yokuthola elinganiselayo, kanye nemikhiqizo yezentengiso ngokuvamile idinga ukwenqatshwa okujwayelekile okujwayelekile kwe-25DB.
4.Ngalungu
Amandla alinganayo ngomsindo Izingxenye eziphambili zomsindo wokulinganisa olinganiselayo zingumsindo wokusakazeka we-Optical kanye nomsindo kagesi.
Ukusetshenziswa kwe-PhotoDETeTector (i-Optoelectronic Balance Detector)
Eminyakeni yamuva nje, ibhalansi ye-PhotoDector isetshenziswe kabanzi emasimini afana ne-laser wind radar, ukucasha okubonakalayo okubuthakathaka, ukutholwa kokubukeka okubuthakathaka, ukutholwa kwegesi, njll. Ucwaningo ngejubane eliphezulu, i-bandwidth ephezulu, ephansi Isilinganiso se-Noise, Imodi Ejwayelekile Yenqabela Imodi Yesabelo, Futhi Ukuzwela Okuphezulu Kwabakwa-Balanced Storictors kwenzele ama-Breactroughs futhi kuthuthukisa ukuhlanganiswa okuphezulu kanye nokusetshenziswa kwamandla okuphansi ukuze uhlangane Izimo ezihlukile zohlelo lokusebenza.
