Phatikizani zithunzi: Kuyambitsa kusamala Photodtector

Mawu OyambaKusamala Photodtector.
Kusamala Photodtecactor ikhoza kugawidwa mu mtundu wa fiber Coumpling mtundu wa mtundu wophatikizika malinga ndi njira yophatikizira yolumikizira. Pakati, imakhala ndi zithunzi ziwiri zofananira, phokoso lotsika, gawo lalitali la ma bandwidth aty Empufirier, ndi gawo lotsika lamphamvu. Ili ndi mawonekedwe a ma moded wamba otsutsa kuchuluka kwa phokoso, phokoso lotsika kwambiri, komanso bandwidth yayikulu, ndipo imagwiritsidwa ntchito kwambiri pankhani yolankhulana kogwirizana. Yakhala hopsot yofufuzira ya mabizinesi ndi mayunivesite osiyanasiyana m'maiko osiyanasiyana m'zaka zaposachedwa.
Kugwirira Mfundo Yabwino Yogwirizira (OptoecleCectronic Controby)
Njira yothetsera njirayi imagwiritsa ntchito zithunzi ziwiri zosinthira ku BIAS monga kuwunika koyenera. Mukalandira chizindikiro chopepuka, chithunzi chomwe chimapangidwa ndi zithunzi ziwirizi zimachotsedwa ndikuphatikizidwa ndi tramplem yotsitsimutsa kuti isinthe chizindikiro cham'madzi kukhala chizindikiro cha voliyumu. Kugwiritsa ntchito njira yochepetsera kusokoneza chizindikiro chimodzi chodziwika bwino chokhazikitsidwa ndi kuwala kwa oscillator ndi chakuda, kuwonjezera njira yosiyanitsa, komanso kuti musinthe kuthekera kwa zizindikiro zofooka.
Ubwino: Njira Yokwera Kwambiri Kukana Kubwezeretsa Raio, chidwi chachikulu, ndi bandwidth kwambiri imatha kukwaniritsa zochitika zingapo zofunsira.
Zovuta: Mphamvu yotsika yotsika yotsika, yoyenera kupezeka kwa kupezeka kwa kuwala, kuphatikiza kuyenera kusintha.

1. Kumvera
Kumvera kumatanthauza kuchita bwino kwa prodidede potembenuza chizindikiro chopepuka mu propy, chomwe ndi chiwerengero cha propyrint kuti chikhale chopepuka. Kusankha Photoodide ndi maudindo apadera kumatha kusintha chidwi cha njira yosinthira.

2. Bandwidth
Bandidth imayimira pafupipafupi chizindikiro chomwe chizindikiritsani matalikidwe a Secodeter, ndipo akugwirizana ndi kuphatikizika kwa ampsifar.
3..
Gawo wamba Resension limagwiritsidwa ntchito pofufuza digiri yopendekera yosiyanasiyana ndi zojambula zamalonda, komanso zinthu zamalonda zimafunikira kukana kwenikweni kwa 25dB.
4.nep
Mphamvu Yofanana: Mphamvu yolowera imafunikira pagawo la chizindikiro cha 1, lomwe ndi gawo lofunikira pakuyeza madongosolo a dongosolo. Zigawo zikuluzikulu za chojambula choyenera ndi phokoso logawika komanso phokoso lamagetsi.

Kugwiritsa ntchito njira yoyang'anira
M'zaka zaposachedwa, sangalalani ndi minda monga laser Grad, hibrar ipsic, yopanda pake yolumikizira, etcwidth yathyamwamba, yotsika phokoso, mayendedwe okwera omwe amakana kuchuluka kwa Ruio, ndipo chidwi chachikulu cha zojambulazo zoyenera zapanga zopukutira ndipo zikukula kukhazikika kwamphamvu komanso kugwiritsa ntchito mphamvu zochepa zothana ndi zosiyana Zolemba.
