ʻO ka noi ʻana o ka ʻōnaehana ana ʻana o ka fiber optic i hāʻawi ʻia a me ke kumu o ka puʻupuʻu fiber optic sensor

ʻIke wela optic, Pūnaehana nānā naʻauao, Hāʻawi ʻia ka mea hana fiber optic ma Kina

Noi o Hoʻolaha ʻia nā Fiber Optic Temperature Sensors ma luna o nā pūʻali ma nā kahua like ʻole

I nā makahiki i hala iho nei, Ua loaʻa i nā mea naʻau fiber optic ka manaʻo nui ma muli o ko lākou kiʻekiʻe kiʻekiʻe, kū'ē i ka hoʻopili electromagnetic, ʻinoʻino, kiʻekiʻe wela, a me ka laulā ana ākea. Ua hoʻomohala ʻia lākou a hoʻohana ʻia i nā ana ʻoihana a me nā kahua hana. Iwaena o lakou, puunaue fiber optic sensing nenoai loa-mamao puunaue ike hiki, ka hoʻokumu ʻana i nā pono noi i hiki ʻole i nā mea ʻike ʻē aʻe ke hoʻololi i kekahi mau kahua (e like me ke kaʻaahi a me ka aila a me ke kinoea pipeline lōʻihi puʻunaue ana wela kahua).

Ke holomua mau nei ka ʻenehana noʻonoʻo fiber optic a ua hoʻohana nui ʻia i nā kula he nui e like me ka pūʻali koa, pale aupuni, aerospace, ʻoihana ʻoihana a me nā ʻoihana eli, ikehu a me ka hoomalu kaiapuni, ʻoihana hoʻomalu, etc. He nui kona mau pono e like me ka ikaika anti-interference, hilinaʻi kiʻekiʻe, a hiki ke kau ʻia i loko o nā wahi paʻakikī like ʻole. Me ka holomua mau o ka ʻenehana ʻike fiber optic, hāʻawi ʻia ka ʻenehana ʻike fiber optic, ma ke ʻano he ʻenehana sensing hiki ke hoʻohana ʻia no ka nānā ʻana i kahi lōʻihi, ua hoʻomaka e hoʻohana nui ʻia i ka nānā ʻana i ka palekana o nā paipu ahi. Hoʻoemi ʻia ka ʻenehana ʻike fiber optic i ka manpower a me nā kumuwaiwai e pono ai ma ka laina ʻike a hoʻomaikaʻi i ka pono o ka nānā ʻana ma o ke kau ʻana i nā kaula optical ma ka laina nānā., ke kālailai ʻana i nā hōʻailona o kēlā me kēia wahi nānā i ka manawa maoli, ʻike naʻauao i nā ʻano hana i kēlā me kēia wahi, a me ka hoʻopuka ʻana i nā ʻōhumu kūpono.

Hoʻokaʻawale ʻia ke ana wela optic no ke ana wela uwea

Me ka hoʻokō ʻana i ka hoʻoponopono hou ʻana i ka mana o ke kūlanakauhale a me ka emi ʻana o nā kumukūʻai noi kelepona, Ua hoʻohana nui ʻia nā kaula uila. Ma kekahi mau kūlanakauhale ma Kina, Ua hoʻololi mālie ʻia nā laina ma luna, akā ʻo ka hoʻohana ʻana o nā kaula i alakaʻi i ka piʻi nui ʻana i ko lākou nui a me nā pilikia i hana ʻia e ka manawa hana lōʻihi.. No laila, mau uwea hewa, a me nā pilikia e like me ka lōʻihi a me ka wahi o nā hewa uwea ua hoʻokipa nui ʻia. ʻOi aku i kēia manawa, ʻO nā hono o nā kaula ka mea kūpono loa i nā hewa o nā kaula mana. Eia naʻe, ʻO ka mālama hewa ʻole a me ka nānā ʻana i nā hono e alakaʻi pinepine ai i ka pau ʻana o ka mana a me ka mālama ʻana, ka hopena i kekahi mau poho waiwai.

ʻO ke kumu o ka ʻenehana ʻike fiber optic

Ke hoʻouna ʻia nā nalu māmā me nā fiber optical ma lalo o ke kumu o ka noʻonoʻo holoʻokoʻa a komo i nā probes sensing optical (hiki ke lilo i nā fiber optical a i ʻole nā ​​mea photosensitive ʻē aʻe), hoʻololi ka ʻimi ʻike i ka hōʻailona māmā ma lalo o ka mana o nā ʻāpana ana i waho (mahana wela, kaomi, deformation, ka wikiwiki, mākū mākia, etc.), hoʻololi i ka ikaika, kūlana polarization, hopena hoʻopilikia, hopena ʻokoʻa, hopena hoʻopuehu, etc. o nā nalu māmā e lilo i kukui hōʻailona modulated. A laila, lawe ʻia ma o nā fiber optical i ka photodetector a me ka demodulator, ka unuhi ʻana i nā ʻāpana e like me ka ikaika māmā, pae, amplitude, kūlana polarization, ka nalu e hōʻike ana i nā ʻano o ka hōʻailona māmā, a me ka demodulate i nā hoʻololi i ana ʻia ma muli o ko lākou mau loli.

I nā makahiki i hala iho nei, me ka piʻi mālie ʻana o nā hale kiʻekiʻe ma Kina, ua piʻi nui nā koi no nā lua kumu ma nā hale. ʻO ka leakage o nā paia mau i lalo o ka ʻenekinia lua kumu he mea nui e pili ana i ka palekana ʻenekinia. ʻO ke kiʻi ʻana i nā ʻenehana ʻike hilinaʻi e hoʻoholo i ka manawa a me ke kiʻekiʻe o ka leakage ua hoʻonui nui ʻia ka nānā ʻana a me ka nānā ʻana i ke kahua ʻenekinia.. I kēia manawa, ʻO nā ala i hoʻohana ʻia no ka ʻike leakage ʻo ia ka ʻike uila, nā mea ʻike capacitive, etc. Eia naʻe, He mau palena kēia mau ʻano a ʻaʻole hiki ke hoʻohana maikaʻi ʻia i ka ʻike leakage o nā paia mau i lalo. ʻO ka ʻenehana ʻike wela o ka fiber optic i hāʻawi ʻia i kēia manawa ka mea i hoʻohana nui ʻia a kūpono hoʻi no ka ʻike ʻana i ka leakage ma nā paia mau o lalo.. Hāʻawi ka ʻenehana Fiber optic sensing i kahi ana ana wela o ka fiber optic ma muli o ka ʻike ʻana i ka leakage o ka paia mau i lalo o ka pā no ka nānā ʻana i ka ʻaila a me ka pipili paipu kino a me ka nānā ʻana i nā hanana leakage dam.. He mea nui e ʻike i ka wahi leakage a me ke degere. Hiki iā ia ke pale i ka hiolo ʻana o ka pā, nā pilikia mālama manawa, a e hōʻoia i ka palekana o ka papahana a me ka palekana o nā ola a me nā waiwai o nā kānaka.

Hoʻolaha ʻia ka ʻenehana ʻike fiber optic

I ka hāʻawi ʻia ʻana o ka fiber optic sensing ʻenehana, ʻO ka fiber optic kahi mea hoʻouna ʻike a me kahi ʻāpana ʻike. ʻO ka ʻenehana ʻike wela Raman i hāʻawi ʻia he ʻenehana noʻonoʻo fiber optic i hoʻohana ʻia no ke ana manawa maoli o ka hāʻawi ʻana i ke kahua wela.. Ma muli o ka hoʻopuehu ʻana o Raman, ʻO ke kukui anti Stokes pili i ka mahana, akā, ʻaʻole pili ka kukui Stokes i ka mahana. Hiki ke hoʻohana ʻia kēia waiwai e ana i ka puʻunaue wela ma luna o ka lōʻihi holoʻokoʻa o ka fiber optic.
