ʻO ke kukui a mākou i kamaʻāina loa ai, ʻo ia nō ka mālamalama a mākou e ʻike ai me ka maka ʻōlohelohe.Hoʻopili loa ko mākou mau maka i ke kukui poni me ka nalu o 400nm i ke kukui ʻulaʻula ma 700nm.Akā no nā fiber optical e lawe ana i nā fiber glass, hoʻohana mākou i ka mālamalama i ka ʻāina infrared.ʻOi aku ka lōʻihi o kēia mau kukui, ʻaʻole i ʻike ʻia e ka maka.E hāʻawi kēia ʻatikala iā ʻoe i ka wehewehe kikoʻī o ka nalu o ka fiber optical a me ke kumu e koho ai ʻoe i kēia mau nalu.
Wehewehe o ka nalu
ʻOiaʻiʻo, ua wehewehe ʻia ka mālamalama e kona lōʻihi nalu.ʻO ka lōʻihi hawewe he helu e hōʻike ana i ke kiko o ka mālamalama.ʻO ke alapine, a i ʻole ka waihoʻoluʻu, o kēlā me kēia kukui he loaʻa nalu e pili ana me ia.Pili ka lōʻihi nalu a me ke alapine.ʻO ka ʻōlelo maʻamau, ʻike ʻia ka radiation hawewe pōkole e kona lōʻihi nalu, ʻoiai ʻike ʻia ka radiation hawewe lōʻihi e kona alapine.
Nā lōʻihi nalu maʻamau i nā fiber optical
ʻO ka lōʻihi nalu maʻamau ʻo 800 a 1600nm, akā i kēia manawa, ʻo nā nalu maʻamau i hoʻohana ʻia i nā fiber optical he 850nm, 1300nm a me 1550nm.He kūpono ke fiber multimode no nā nalu nalu o 850nm a me 1300nm, ʻoiai ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka fiber mode hoʻokahi no nā nalu o 1310nm a me 1550nm.ʻO ka ʻokoʻa ma waena o ka nalu o 1300nm a me 1310nm aia wale nō ma ka inoa maʻamau.Hoʻohana pū ʻia nā lasers a me nā diodes māmā no ka hoʻolaha māmā ʻana i nā fiber optical.ʻOi aku ka lōʻihi o nā lasers ma mua o nā mea hana hoʻokahi me nā nalu nalu o 1310nm a i ʻole 1550nm, ʻoiai e hoʻohana ʻia nā diodes māmā no nā mea multimode me nā nalu o 850nm a i ʻole 1300nm.
No ke aha e koho ai i kēia mau nalu?
E like me ka mea i ʻōlelo ʻia ma mua, ʻo nā lōʻihi nalu maʻamau i hoʻohana ʻia i nā fiber optical he 850nm, 1300nm a me 1550nm.Akā, no ke aha mākou e koho ai i kēia mau hawewe ʻekolu o ka mālamalama?ʻO ia no ka mea ʻoi aku ka liʻiliʻi o nā hōʻailona optical o kēia mau hawewe ʻekolu i ka wā i hoʻoili ʻia i ka fiber optical. pohō hoʻopuehu. Loaʻa ka poho ʻana ma kekahi mau nalu kikoʻī i kapa ʻia ʻo "nā pūʻali wai", ma muli o ke komo ʻana o nā kulu wai i loko o ka mea aniani.ʻO ka hoʻopuehu ʻia ma muli o ka rebound o nā ʻātoma a me nā molekala ma ke aniani.ʻOi aku ka liʻiliʻi o ka lūlū nalu lōʻihi, ʻo ia ka hana nui o ka nalu.
I ka hopena
Ma hope o ka heluhelu ʻana i kēia ʻatikala, loaʻa paha iā ʻoe kekahi ʻike maʻamau o nā lōʻihi nalu i hoʻohana ʻia i nā fiber optical.No ka haʻahaʻa haʻahaʻa o ka haʻahaʻa haʻahaʻa o 850nm, 1300nm a me 1550nm, ʻo lākou ke koho maikaʻi loa no ka kamaʻilio fiber optical.
