Fiber Optic Sensor
Hoʻokumu ʻia ka mea ʻike fiber optic me kahi kumu kukui, kahi fiber hanana, kahi fiber puka, modulator māmā, ʻike kukui, a me kahi demodulator. ʻO ke kumu kumu, ʻo ia ka hoʻouna ʻana i ke kukui o ke kumu kukui i ka wahi modulation ma o ka fiber hanana, a pili ke kukui me nā ʻāpana i ana ʻia i waho i ka wahi modulation e hana i nā waiwai optical o ka mālamalama (e like me ka ikaika, ka lōʻihi o ka nalu, ka pinepine. , pae, deviation maʻamau, etc.) hiki mai. ʻO ke kukui hōʻailona i hoʻololi ʻia e lilo i kukui hōʻailona modulated, a laila e hoʻouna ʻia i ka photodetector a me ka demodulator ma o ka fiber puka e loaʻa ai nā ʻāpana i ana ʻia.
Hiki ke hoʻokaʻawale ʻia nā mea ʻike fiber Optical i ʻelua mau ʻāpana e like me ke ʻano o ke ʻano: ʻo kekahi mea ʻike hana (sensing); ʻo ka mea ʻē aʻe he mea ʻike ʻole (hoʻouna kukui).
ʻIke hana
E hoʻohana i ka fiber optical (a i ʻole ka fiber optical kūikawā) me ka ʻike a me ka hiki ke ʻike i ka ʻike o waho ma ke ʻano he mea ʻike e hoʻololi i ke kukui i hoʻouna ʻia i loko o ka fiber optical e hoʻololi i ka ikaika, ka pae, ka pinepine a i ʻole ka polarization o ke kukui i hoʻouna ʻia. Ma ka demodulate i ka hōʻailona modulated, loaʻa ka hōʻailona ana.
ʻAʻole ʻo ka fiber optical he ala alakaʻi māmā wale nō, akā he mea koʻikoʻi nō hoʻi, a hoʻohana nui ʻia ka fiber optical multi-mode.
Pōmaikaʻi: hoʻolālā paʻa a me ka naʻau kiʻekiʻe. Nā pōʻino: Pono nā fiber optical kūikawā, a he kiʻekiʻe ke kumukūʻai. Nā hiʻohiʻona maʻamau: fiber optic gyroscopes, fiber optic hydrophones, etc.
ʻO ka mea ʻike ʻole hana
Hoʻohana ia i nā ʻāpana koʻikoʻi ʻē aʻe e ʻike i nā loli i ana ʻia. Hoʻohana wale ʻia ka fiber Optical ma ke ʻano he mea hoʻouna i ka ʻike, a hoʻohana pinepine ʻia ka fiber optical mode hoʻokahi. ʻO ka fiber optical wale nō ke kuleana i ke alakaʻi ʻana i ke kukui, a ua ana ʻia ka māmā a hoʻololi ʻia ma ka mea ʻano ʻano ʻano hiʻona.
Pōmaikaʻi: ʻAʻole pono i nā fiber optical kūikawā a me nā ʻenehana kūikawā ʻē aʻe, maʻalahi ke hoʻokō, a me ke kumu kūʻai haʻahaʻa. Nā hemahema: haʻahaʻa haʻahaʻa. ʻO ka hapa nui o nā mea hoʻohana he mau mea ʻike fiber optical non-functional.
