Photodetector Series: Nhanganyaya yekuenzanisa Photodetector

NhanganyayaBalance Photodetector(Optoelectronic Balance Detector)
Balance photosdek inogona kukamurwa kuita fiber optic coupling mhando uye spatial Optical coupling mhando zvinoenderana nenzira yeOptical Coupling nzira. Mukati, iyo ine maviri akanyanya kufananidzirwa mafoto, yakaderera-ruzha, yakakwira bandwidth transimped Iyo ine maitiro ezvakakwirira zvakajairika mode kurambwa ratio, Ultra-low ruzha, uye yakakwira bandwidth, uye inoshandiswa zvakanyanya mumunda wekukurukurirana kwechokwadi. Yave iri hotspot yeHotspot yemabhizinesi nemayunivhesiti munyika dzakasiyana siyana mumakore achangopfuura.
Kushanda kwehunyanzvi hweBalance Photosdetector (Optoelectronic Balance Detector)
Iyo Balance Photodetector inoshandisa maviri mafotodhi mune reverse bias state seyechiedza ichigamuchira unit. Paunenge uchigamuchira chiratidzo chechiedza, iyo photoscrent inogadzirwa neyakagadzirwa neyakagadzirwa neyakagadziriswa Iko kushandiswa kwekuzvinyudza kuderedza kunogona kudzvinyirira maitiro akajairwa maitiro akasvitswa neyekupedzisira
Zvakanakira: Yakakwirira yakajairika mode kurambwa ratio, yakanyanya kunzwa, uye yakakwirira yekuona bandwidth inogona kusangana zvakasiyana siyana zvekushandisa.
Zvinokuvadza: Yakadzika yakawandisa Simba simba, yakakodzera chete kune isina kusimba mwenje wekuona, kubatanidzwa kunoda kuvandudzwa.

Performance parameter eBalance Photodetector (OptoelectronicBalance Detector)
1. Kupindura
Kutevedzera kunoreva kugona kweiyo fotodiode mukushandura zviratidzo zvechidimbu muPlaculrrent, iyo iri chiyero cheiyo fotocurrent kune simba rakachena. Kusarudza photodiode ine nhare yepamusoro inogona kubatsira zvinobudirira kunzwira tsitsi kweiyo balance photosetector.

2. Bandwidth
Iyo bandwidth inomiririra chiratidzo chekusarongeka pane iyo yekubuda chiratidzo cheiyo balicector yekusaora neiyo fotodhi yePotsiode, iyo saizi yekufambisa, uye iyo yekuwana bandwidth chigadzirwa chekushanda omplifier.
3. Zvakajairika mode kurambwa ratio
Yakajairika mode kurambwa ratio inoshandiswa kuyera iyo nhanho yekudzvinyirira yemamiriro ezvinhu akajairika nezvakaringana, uye zvigadzirwa zvekutengesa zvinowanzoda kuderera kuwanda kwemamiriro ezvinhu 25DB.
4.Nep
Ruzha rwakaenzana Simba: Iyo Signs Signal Simba inodiwa pane chiratidzo-kune-ruzha ratio ye1, iyo iri yakakosha paramende yekuyera kurira kwehurongwa hwegadziriro. Izvo zvinhu zvikuru zveyero zvine mwero detector ruzha nderemo rekuparadzira ruzha uye ruzha rwemagetsi.

Kushandiswa kweBalance Photodetector (OptoelectRonic Balance Detector)
Mumakore achangopfuura ruzha, yakakwirira yakajairika mode kurambwa ratio, uye kunzwa kwepamusoro kwevanhurume vane mwero kwakaitwa nekureba uye kuri kukura kusvika pakubata kwakanyanya uye kushaya simba kusangana akasiyana ekushandisa zviitiko.
