He aha ka Fiber Optic Delay Line OFDL

ʻO ka Fiber Optical Delay Line (OFDL) kahi mea hiki ke hoʻokō i ka lohi manawa o nā hōʻailona optical. Ma ka hoʻohana ʻana i ka lohi, hiki iā ia ke hoʻokō i ka hoʻololi ʻana i ka pae, ka mālama ʻana i nā mea āpau a me nā hana ʻē aʻe. Loaʻa iā ia ka laulā o nā noi i ka radar array phased, nā ʻōnaehana kamaʻilio fiber optic, nā mea hoʻohālikelike uila, ka noiʻi ʻepekema a me ka hoʻāʻo ʻana, a me nā kahua ʻē aʻe. E hoʻomaka ana kēia ʻatikala mai nā kumu kumu o nā laina hoʻopaneʻe fiber optic, e kālele ana i nā hiʻohiʻona noi a pehea e koho ai i ka laina hoʻopaneʻe fiber optic kūpono.
Kuʻuna hana
ʻO ke kumu kumu o ka laina hoʻopaneʻe fiber optic ʻo ia ka hoʻouna ʻana i ka hōʻailona optical e hoʻopaneʻe ʻia ma o kahi lōʻihi kikoʻī o ka fiber optic cable, a ma muli o ka manawa e pono ai no ka lawe māmā ʻana i ke kaula fiber optic, ua hoʻokō ʻia ka manawa lohi o ka hōʻailona optical. E like me ka mea i hōʻike ʻia ma ke Kiʻi 1, ʻo ka laina hoʻopaneʻe fiber optic maʻalahi he ʻōnaehana i haku ʻia me nā mea hana e like me nā lasers, modulators, fiber transmission, a me nā photodetectors me ka hana lohi hōʻailona. Ke kumu hana: ʻO ka hōʻailona RF e hoʻouna ʻia a me ka hōʻailona optical i hoʻopuka ʻia e ka laser e hoʻokomo ʻia i nā modulators like ʻole. Hoʻololi nā modulators i ka hōʻailona RF ma ke kukui e hana i kahi hōʻailona optical e lawe ana i ka ʻike RF. Hoʻopili ʻia ka hōʻailona optical e lawe ana i ka ʻike RF i ka loulou fiber optic no ka hoʻouna ʻana, lohi no kekahi manawa, a laila hiki i ka photodetector. Hoʻololi ka mea ʻike kiʻi i ka hōʻailona optical i loaʻa e lawe ana i ka ʻike RF i kahi puka hōʻailona uila.

Kiʻi 1 Kūlana Kūlana o Optic Fiber Delay Line OFDL

Nā hiʻohiʻona noiʻi
1.Phased array radar: ʻO ka mea nui o ka radar array phased ʻo ia ka antenna array phased. ʻAʻole mamao loa nā antenna radar kuʻuna mai ka hoʻokō ʻana i nā koi o nā ʻōnaehana radar, ʻoiai ʻo nā laina hoʻopaneʻe fiber optic i kā lākou mau pono hana kūikawā i ka hoʻohana ʻana i nā antennas array phased. No laila, he koʻikoʻi koʻikoʻi nā laina lohi o ka fiber optic i ka radar array phased.
2.Fiber optic communication system: Hiki ke hoʻohana i nā laina hoʻopaneʻe fiber optic no ka hoʻokō ʻana i nā papahana hoʻopāpā kikoʻī. Ma ka hoʻokomo ʻana i nā lohi like ʻole i nā manawa manawa like ʻole, hiki ke hana ʻia nā hōʻailona hoʻopā ʻana me nā hiʻohiʻona kikoʻī, he mea maikaʻi ia no ka hoʻomaikaʻi ʻana i ka hiki ke pale aku i nā hōʻailona ma nā ʻōnaehana kamaʻilio kikohoʻe. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he mālama manawaleʻa (cache) e mālama i kekahi mau ʻikepili, a pēlā aku. I ka pōkole, ʻo nā laina hoʻopaneʻe fiber optic he ākea ka nui o nā noi ma nā kahua he nui ma muli o ko lākou bandwidth kiʻekiʻe, haʻahaʻa haʻahaʻa, a me ke kūʻē ʻana i ka interference electromagnetic. Inā ma ke kahua kamaʻilio, radar, hoʻokele, a i ʻole ke kiʻi lāʻau lapaʻau, paʻa lākou i nā kuleana koʻikoʻi.
