Urukurikirane rwa Photodetector: Intangiriro Kuringaniza Photodetector

Intangiriro kuriKuringaniza Photodetector(Optoelectronic Balance Detector)
Kuringaniza Photodetector irashobora kugabanwa muburyo bwa fibre optique hamwe nubwoko bwa optique bwo guhuza ukurikije uburyo bwo guhuza optique. Imbere, igizwe na fotodi ebyiri zihuye cyane, urusaku ruke, umuvuduko mwinshi wa transimpedance amplifier circuit module, hamwe na ultra-low power power module. Ifite ibiranga uburyo busanzwe bwo kwangwa, urusaku ruke-ruke, hamwe n’umuvuduko mwinshi, kandi rukoreshwa cyane mubijyanye n’itumanaho rya optique. Yabaye ahantu h’ubushakashatsi ku mishinga na kaminuza mu bihugu bitandukanye mu myaka yashize.
Ihame ryakazi rya Balance Photodetector (Indangantego ya Optoelectronic)
Balanse Photodetector ikoresha fotodi ebyiri muburyo bubogamye nkibice byakira urumuri. Iyo wakiriye ibimenyetso byoroheje, fotokorent yakozwe na fotodi ebyiri ikuramo kandi igahuzwa na transimpedance amplifier kugirango ihindure ibimenyetso byubu mubimenyetso bya voltage kugirango bisohore. Gukoresha uburyo bwo kugabanya imiterere irashobora guhagarika neza ibimenyetso byuburyo busanzwe bwatangijwe n’umucyo wa oscillator w’umucyo hamwe n’umuyaga wijimye, byongera ibimenyetso byerekana uburyo butandukanye, kandi ku rugero runaka bizamura ubushobozi bwo kumenya ibimenyetso by’urumuri rudakomeye.
Ibyiza: Ikigereranyo cyo hejuru cyo kwangwa muburyo bukabije, ibyiyumvo byinshi, hamwe numuyoboro mugari urashobora guhura nibintu bitandukanye.
Ibibi: Imbaraga za optique zuzuye, gusa zikwiranye no kumenya urumuri rudakomeye, kwishyira hamwe bigomba kunozwa.

Imikorere yimikorere ya Balanse Photodetector (OptoelectronicKuringaniza)
1. Kwitabira
Kwitabira bivuga imikorere ya fotodiode muguhindura ibimenyetso byumucyo gufotora, nicyo kigereranyo cyamafoto nimbaraga zumucyo. Guhitamo fotodiode hamwe nubushobozi buhanitse birashobora kunoza neza sensibilité ya Balance Photodetector.

2. Umuyoboro mugari
Umuyoboro mugari werekana ibimenyetso byerekana inshuro zerekana ibimenyetso byerekana amplitude ya Balance Photodetector yangirika na -3dB, kandi ifitanye isano na capacitance ya parasitike ya fotodiode, ingano ya transimpedance, hamwe ninyungu yumurongo wibikorwa bya amplifier ikora.
3. Ikigereranyo gisanzwe cyo kwangwa
Ikigereranyo gisanzwe cyo kwangwa gikoreshwa mugupima urwego rwo guhagarika ibimenyetso byuburyo busanzwe hamwe nubushakashatsi buringaniye, kandi ibicuruzwa byubucuruzi bisaba byibuze kwangwa muburyo busanzwe bwo kwangwa 25dB.
4.NEP
Urusaku Ruringaniza Imbaraga: Imbaraga zerekana ibimenyetso bisabwa ku kimenyetso cyerekana urusaku rwa 1, nikintu cyingenzi mugupima imikorere y urusaku rwa sisitemu. Ibice byingenzi bigize urusaku ruringaniza urusaku ni urusaku rukwirakwiza urusaku n urusaku rwamashanyarazi.

Ikoreshwa rya Balanse Photodetector (Optoelectronic Balance Detector)
Mu myaka yashize, Balance Photodetector yakoreshejwe cyane mubice nka lazeri yumuyaga wa laser, gupima vibrasi ya laser, fibre optique, sensibilité yumucyo utagaragara, gutahura ibintu, gutahura gaze, nibindi.
