Fiber Optic Sensor
Fiber optic sensor imapangidwa ndi gwero la kuwala, ulusi wa zochitika, ulusi wotuluka, modulator yowunikira, chowunikira kuwala, ndi demodulator.Mfundo yayikulu ndikutumiza kuwala kwa gwero la kuwala kumalo osinthika kudzera mu fiber yomwe ikuchitika, ndipo kuwala kumayenderana ndi magawo akunja omwe amayezedwa m'dera la modulation kuti apange kuwala kwa kuwala (monga mphamvu, wavelength, frequency). , gawo, kupatuka kwabwinobwino, etc.) zimachitika.Kuwala kosinthika kwa chizindikiro kumakhala kuwala kosinthika, komwe kumatumizidwa ku photodetector ndi demodulator kudzera mu fiber yotuluka kuti mupeze magawo omwe amayezedwa.
Optical fiber sensors akhoza kugawidwa m'magulu awiri malinga ndi mtundu wa kamangidwe: imodzi ndi yogwira ntchito (yomverera);ina ndi sensa yosagwira ntchito (yotumiza kuwala).
Sensa yogwira ntchito
Gwiritsani ntchito nsonga ya kuwala (kapena kuwala kwapadera) ndi chidziwitso ndi chidziwitso chakunja kwa chidziwitso chakunja monga chinthu chodziwitsira kuti musinthe kuwala komwe kumaperekedwa mu kuwala kwa kuwala kuti musinthe mphamvu, gawo, mafupipafupi kapena polarization ya kuwala kofalitsidwa.Mwa kutsitsa chizindikiro chosinthidwa, chizindikiro choyezedwa chimapezeka.
Ulusi wowoneka bwino siwongowongolera wowunikira, komanso chinthu chodziwika bwino, ndipo ulusi wamitundu yambiri umagwiritsidwa ntchito kwambiri.
Ubwino: kapangidwe kakang'ono komanso kukhudzika kwakukulu.Zoipa: Ulusi wapadera wa kuwala umafunika, ndipo mtengo wake ndi wokwera.Zitsanzo zodziwika bwino: fiber optic gyroscopes, fiber optic hydrophones, etc.
Sensa yosagwira ntchito
Imagwiritsa ntchito zigawo zina zokhudzidwa kuti zizindikire kusintha komwe kukuyezedwa.Ulusi wa Optical umangogwiritsidwa ntchito ngati njira yotumizira zidziwitso, ndipo mawonekedwe amodzi amagwiritsidwa ntchito nthawi zambiri.Ulusi wa kuwala umangothandiza pakuwongolera kuwala, ndipo kuwalako kumayesedwa ndi kusinthidwa pa chinthu chokhudzidwa ndi mtundu wa fiber.
Ubwino wake: Sipafunikanso ulusi wapadera wa kuwala ndi umisiri wina wapadera, wosavuta kugwiritsa ntchito, komanso wotsika mtengo.Zoipa: kukhudzika kochepa.Zambiri mwazomwe zimagwiritsidwa ntchito ndi zosagwira ntchito za optical fiber sensors.
