Ma photodetectors atsopano amasintha ukadaulo wa optical fiber kulumikizana ndi kuzindikira

Zatsopanoma photodetectorssinthani ukadaulo wolumikizirana ndi kuwala kwa fiber

Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, njira zolumikizirana ndi ma fiber optical fiber sensing zikusintha miyoyo yathu. Kugwiritsa ntchito kwawo kwalowa m'mbali zonse za moyo watsiku ndi tsiku, kuchokera pakulankhulana pa intaneti mpaka pakuzindikira zachipatala, kuchokera ku makina opanga makina kupita ku kafukufuku wasayansi. Posachedwapa, mtundu watsopano waPhotodetectorwasintha machitidwe onse awiri.
Photodetector iyi imaphatikiza aChithunzi cha PINndi chigawo chochepa cha amplifier cha phokoso lapamwamba la bandwidth yogwiritsira ntchito komanso kutaya kutsika kochepa. Izi zikutanthauza kuti imatha kutenga chizindikiro cha kuwala mu nthawi yochepa kwambiri ndikuchisintha kukhala chizindikiro chamagetsi, motero kukwaniritsa kutembenuka kwa photoelectric mofulumira komanso kothandiza.

Kuphatikiza apo, kutalika kwa mawonekedwe a photodetector kumakwirira 300nm mpaka 2300nm, kuphimba pafupifupi mafunde onse owoneka ndi ma infrared. Katunduyu amathandizira kuti agwiritsidwe ntchito mumitundu yosiyanasiyana yamakasitomala ndi zowonera.
Photodetector ili ndi mawonekedwe a analogi ndi ntchito zokulitsa, zomwe zimatha kukulitsa zizindikiro zofooka zowunikira kuti zitha kuzindikirika ndi chida munthawi yochepa kwambiri. Izi zimapangitsa kuti zikhale ndi gawo lofunikira m'magawo monga optical communication, spectral analysis, lidar ndi zina zotero.
Kuphatikiza pa kukhala wamphamvu, photodetector iyi ndi yochenjera kwambiri pakupanga. Chipolopolocho chimapangidwa kuti chiteteze fumbi ndi kusokoneza kwa ma electromagnetic, zomwe zingateteze bwino dera lamkati kuti lisasokonezedwe ndi kunja. Nthawi yomweyo, mawonekedwe ake a SMA linanena bungwe kumapangitsa kukhala kosavuta kulumikizana ndi zida zina.
Ndikoyenera kutchula kuti chipolopolo cha photodetector ichi chili ndi dzenje la ulusi, kotero kuti likhoza kukhazikitsidwa pa nsanja ya kuwala kapena zipangizo zoyesera, zomwe zimathandizira kwambiri ntchito yoyesera.
Ponseponse, chowunikira chatsopanochi ndicholimbikitsa kwambiri makina olumikizirana ndi fiber optical fiber sensing system. Kuthamanga kwapamwamba kwa bandwidth ndi kutayika kochepa koyika kumapangitsa kuti photoelectric itembenuke mofulumira komanso mogwira mtima, ndipo kutalika kwa kutalika kwa mawonekedwe ndi kupindula kwakukulu kumapangitsa kuti zigwirizane ndi zochitika zosiyanasiyana zogwiritsira ntchito. Mapangidwe okongola komanso kuyika kosavuta kumakulitsa luso la wogwiritsa ntchito. Kukhazikitsidwa kwa photodetector iyi mosakayikira kudzapititsa patsogolo chitukuko cha optical fiber communication ndi sensing teknoloji, kutitsogolera kudziko latsopano la kuwala.
