Itsvaphotodetectorskuchinja tekinoroji yekutaurirana uye yekunzwa kwe optical fiber
Nekufambira mberi kuri kuita sainzi netekinoroji, masisitimu ekutaurirana nefiber uye masisitimu ekuona fiber ari kuchinja hupenyu hwedu. Kushandiswa kwawo kwakapinda muzvinhu zvese zvehupenyu hwezuva nezuva, kubva pakutaurirana neinternet kusvika pakuongororwa kwezvekurapa, kubva pakushandisa otomatiki kwemaindasitiri kusvika pakutsvagisa kwesainzi. Munguva pfupi yapfuura, mhando itsva yemudziyo wekuona fotoyakachinja masisitimu ese ari maviri.
Iyi photodetector inobatanidzaPIN photodiodeuye dunhu rekusimudzira ruzha rushoma rekushandisa bandwidth yakawanda uye kurasikirwa kwakaderera kwekupinza. Izvi zvinoreva kuti inokwanisa kubata chiratidzo chechiedza munguva pfupi uye kuchishandura kuita chiratidzo chemagetsi, nokudaro ichikwanisa kushandura photoelectric nekukurumidza uye zvinobudirira.
Pamusoro pezvo, huwandu hwemafungu ekuona hwechinotora mifananidzo hunosvika 300nm kusvika 2300nm, huchifukidza anenge mafungu ese anoonekwa uye einfrared. Izvi zvinoita kuti ikwanise kushandiswa mumhando dzakasiyana-siyana dzemaoptical uye sensing systems.
Chinoongorora masaini chine mabasa ekugadzirisa masaini eanalog uye ekuwedzera, izvo zvinogona kuwedzera masaini echiedza asina simba zvekuti anogona kuonekwa nechishandiso ichi munguva pfupi. Izvi zvinoita kuti chikwanise kuita basa rakakosha muminda yakaita sekutaurirana kwemaziso, kuongorora maspectral, lidar nezvimwewo.
Pamusoro pekusimba kwayo, iyi photodetector ine hungwaru hwakanyanya pakugadzira. Goko rayo rakagadzirwa kudzivirira guruva uye electromagnetic interference, izvo zvinogona kudzivirira zvinobudirira internal circuit kubva kunze. Panguva imwe chete, SMA output interface yayo inoita kuti zvive nyore kubatana nezvimwe zvishandiso.
Zvakakosha kutaura kuti goko remuchina uyu wekuona mifananidzo rine buri rakarukwa, kuitira kuti rigone kusungirirwa pachikuva chemaziso kana michina yekuedza, izvo zvinoita kuti kuyedza kushande zvakanaka.
Kazhinji, iyi photodetector itsva inobatsira zvikuru mukukurukurirana kwe optical fiber uye optical fiber sensing systems. Kushanda kwakanyanya uye kurasikirwa kwakaderera kwekuisa kunogonesa kushandurwa kwe photoelectric nekukurumidza uye zvinobudirira, uye huwandu hwakakura hwe wavelength uye kuwedzera kwakanyanya kunoita kuti ikwanise kuchinjika kune akasiyana siyana mashandisirwo ezvinhu. Dhizaini yakanaka uye kuiswa kuri nyore zvinosimudzira ruzivo rwemushandisi. Kutanga kwe photodetector iyi pasina mubvunzo kuchasimudzira kukura kwetekinoroji yekutaurirana ne optical fiber, zvichititungamira munyika itsva yechiedza.
