I ke au o ka holomua ʻenehana, ua puka mai nā ʻōnaehana hoʻokele ma ke ʻano he mau pou kumu, e hoʻoikaika ana i nā holomua he nui, ʻoi aku ka nui o nā ʻāpana koʻikoʻi.ʻO ka huakaʻi mai ka hoʻokele lani kumu mua a hiki i ka Inertial Navigation Systems (INS) e hōʻike ana i nā hoʻoikaika paʻa ʻole o ke kanaka no ka ʻimi ʻana a me ka pololei.ʻO kēia ka nānā ʻana i ka hohonu i loko o nā mīkini paʻakikī o INS, e ʻimi ana i ka ʻenehana ʻokiʻoki o Fiber Optic Gyroscopes (FOGs) a me ke kuleana koʻikoʻi o ka Polarization i ka mālama ʻana i nā Loops Fiber.
Mahele 1: Ka wehewehe ʻana i nā ʻōnaehana hoʻokele inertial (INS):
Kūʻokoʻa ʻo Inertial Navigation Systems (INS) ma ke ʻano he kōkua hoʻokele kūʻokoʻa, e helu pololei ana i ke kūlana o kahi kaʻa, ke ʻano, a me ka wikiwiki, kūʻokoʻa i nā hōʻailona waho.Hoʻolikelike kēia mau ʻōnaehana i nā ʻenekini a me nā ʻenekini hoʻololi, hoʻohui pono ʻia me nā hiʻohiʻona helu no ka wikiwiki mua, kūlana, a me ke ʻano.
Hoʻopili ʻia kahi archetypal INS ʻekolu mau ʻāpana cardinal:
· Nā Accelerometers: Hoʻopaʻa kēia mau mea koʻikoʻi i ka wikiwiki laina o ke kaʻa, e unuhi ana i ka neʻe i ka ʻikepili hiki ke ana.
· Gyroscopes: He mea koʻikoʻi no ka hoʻoholo ʻana i ka velocity angular, he pivotal kēia mau ʻāpana no ka ʻōnaehana ʻōnaehana.
· Module Kamepiula: ʻO ke kikowaena nerve o ka INS, ka hoʻoponopono ʻana i nā ʻikepili multifaceted e hāʻawi i ka ʻikepili kūlana manawa maoli.
ʻO ka pale ʻana o INS i nā pilikia o waho he mea nui ia i nā ʻāpana pale.Eia nō naʻe, e hakakā ana me ka 'drift' - ka palaho pololei ʻana, e koi ana i nā hoʻonā maʻalahi e like me ka sensor fusion no ka hoʻēmi hewa (Chatfield, 1997).
Mahele 2. Nā Hana Hana o ka Fiber Optic Gyroscope:
Hōʻike nā Fiber Optic Gyroscopes (FOGs) i kahi wā hoʻololi i ka ʻike ʻana i ka rotational, e hoʻohana ana i ka hoʻopili ʻana o ka mālamalama.Me ka pololei ma kona kumu, koʻikoʻi nā FOG no ka hoʻokū ʻana a me ka hoʻokele ʻana o nā kaʻa aerospace.
Hoʻohana nā FOG i ka hopena Sagnac, kahi māmā, e hele ana ma nā ʻaoʻao kūʻē i loko o kahi coil fiber wili, e hōʻike ana i kahi neʻe ʻana e hoʻopili ʻia me nā loli o ka rotational.Ke unuhi nei kēia mīkini nuanced i nā metric angular velocity pololei.
ʻO nā ʻāpana koʻikoʻi he:
· Puna Māmā: ʻO ka wahi hoʻomaka, maʻamau he laser, e hoʻomaka ana i ka huakaʻi māmā.
· Huipuʻu pulupulu: ʻO kahi conduit optical coiled, hoʻolōʻihi i ke ala o ka māmā, a laila e hoʻonui ai i ka hopena Sagnac.
· Photodetector: Hoʻomaopopo kēia ʻāpana i nā hiʻohiʻona paʻakikī o ka mālamalama.
Māhele 3: ʻO ke koʻikoʻi o ka polarization e mālama ana i nā Loops Fiber:
Polarization Maintaining (PM) Fiber Loops, quintessential for FOGs, hōʻoiaʻiʻo i kahi kūlana polarization like o ka mālamalama, kahi mea nui e hoʻoholo ai i ka pololei o ke kumu hoʻohālikelike.ʻO kēia mau fiber kūikawā, e hakakā ana i ka hoʻopuehu ʻana o ke ʻano polarization, hoʻoikaika i ka ʻike FOG a me ka ʻoiaʻiʻo o ka ʻikepili (Kersey, 1996).
ʻO ke koho ʻana i nā fibers PM, i kuhikuhi ʻia e nā pono hana, nā ʻano kino, a me ka ʻōnaehana ʻōnaehana, e hoʻopili i nā metric hana nui.
Mahele 4: Nā noi a me nā hōʻike hoʻohālikelike:
Loaʻa nā FOG a me INS i ka resonance ma waena o nā noi like ʻole, mai ka hoʻonohonoho ʻana i nā foray lewa unmanned a hiki i ka hōʻoia ʻana i ka paʻa cinematic ma waena o ka hiki ʻole ke ʻike ʻia.ʻO kahi hōʻike i ko lākou hilinaʻi ʻana ʻo kā lākou hoʻolaha ʻana ma NASA's Mars Rovers, e hoʻomaʻamaʻa i ka hoʻokele extraterrestrial palekana palekana (Maimone, Cheng, a me Matthies, 2007).
Ke wānana nei nā huakaʻi mākeke i kahi niche e ulu nei no kēia mau ʻenehana, me nā vectors noiʻi e kuhikuhi ana i ka hoʻoikaika ʻana i ka ʻōnaehana resilience, precision matrices, a me adaptability spectra (MarketsandMarkets, 2020).

Hoʻolālā o kahi fiber-optic-gyroscope e pili ana i ka hopena sagnac
