Te kaupapa me te whakarōpūtanga o te kohu
(1) te kaupapa
I roto i te ahupūngao, e kiia ana te mātāpono o te kohu ko te pānga Sagnac. I roto i te ara mārama kua kati, ka whakararuraruhia ngā hihi mārama e rua mai i te pūtake mārama kotahi ina tūtaki rāua ki te pūwāhi kitenga kotahi. Mena he hurihanga te ara mārama kua kati e pā ana ki te wāhi inertial, ka puta he rerekētanga ara mārama mai i te hihi e horapa ana i ngā ahunga pai me ngā ahunga kino, he rite ki te tere o te koki hurihanga o runga. Ka tatauhia te tere o te koki hurihanga mā te whakamahi i te rerekētanga ā-wāhanga inehia e te pūoko whakaahua-hiko.
Mai i te tātai, ko te roa o te muka, ko te nui ake o te radius hikoi whatu, ko te poto ake o te roangaru whatu. Ko te kitea nuitia o te pānga pokanoa. Nō reira, ko te nui ake o te rahinga o te kohu, ko te teitei ake o te tika. Ko te pānga Sagnac he pānga whanaungatanga, he mea tino nui mō te hoahoa o te makuku.
Ko te kaupapa o te kohu ko te tukunga o te hihi mārama mai i te ngongo whakaahua-hiko ka haere mā roto i te hononga (ka uru tetahi pito ki ngā tūnga e toru). E rua ngā hihi e tomo ana ki te mowhiti i ngā ahunga rerekē mā roto i te mowhiti, kātahi ka hoki mai i te porowhita kotahi mō te taupatupatu ōrite. Ka hoki te mārama e whakahokia ana ki te LED ka kitea te kaha mā roto i te LED. He māmā noa te kaupapa o te kohu, engari ko te mea nui ko te whakakore i ngā āhuatanga e pā ana ki te ara whatu o ngā hihi e rua—he raruraru nui ko te kohu.
Te kaupapa o te wiri muka whatu
(2) whakarōpūtanga
E ai ki te mātāpono mahi, ka taea te wehewehe i ngā wiri muka whatu ki te wiri muka whatu whakawhiti-ira (I-FOG), te wiri muka whatu whakakoi (R-FOG), me te wiri muka whatu marara Brillouin whakahihiko (B-FOG). I tēnei wā, ko te wiri muka whatu tino pakari ko te wiri muka whatu whakawhiti-ira (te wiri muka whatu whakatupuranga tuatahi), e whakamahia whānuitia ana. Ka whakamahia he koiri muka maha-hurihanga hei whakarei ake i te pānga Sagnac. I tētahi atu taha, ka taea e te wiri mowhiti rua-ira i hangaia mai i te koiri muka kotahi-hurihanga maha-hurihanga te whakarato i te tino tika, ka nui ake te uaua o te hanganga katoa.
E ai ki te momo porowhita, ka taea te wehewehe i te kohu ki te kohu porowhita tuwhera me te KOHU porowhita kati. Ko ngā painga o te gyroscope muka whatu porowhita tuwhera (Ogg) he hanganga māmā, he utu iti, he pono teitei, me te iti o te whakamahinga hiko. I tetahi atu taha, ko ngā ngoikoretanga o te Ogg ko te koretake o te raina whakauru-putanga me te iti o te awhe hihiri. Nō reira, ka whakamahia whānuitia hei pūoko koki. Ko te hanganga taketake o te IFOG porowhita tuwhera he ine whakawhiti rua-rama mowhiti. Nō reira, ka whakamahia whānuitia i roto i te āhuatanga o te iti o te tika me te iti o te rōrahi.
Taupū mahi o te kohu
Ko te kohu te mea nui e whakamahia ana hei ine i te tere koki, ā, he hapa tetahi inenga.
(1) haruru
Ko te tikanga haruru o te kohu kei te nuinga o te wā e arohia ana ki te wāhanga kimi whatu, hiko rānei, e whakatau ana i te iti rawa o te aro o te makuku ka kitea. I roto i te wiri muka-whatu (FOG), ko te tawhā e tohu ana i te haruru ma o te tere koki ko te tauwehenga hikoi matapōkere o te whānui o te kimi. Mō te haruru ma anake, ka taea te whakangawari i te whakamāramatanga o te tauwehenga hikoi matapōkere hei ōwehenga o te pumau o te ine ki te pūtake tapawhā o te whānui o te kimi i roto i tētahi whānui motuhake.
Mena he momo haruru, he momo nekeneke rānei, ka whakamahia e mātou te tātaritanga rerekētanga a Allan hei tiki i te tauwehenga hikoi matapōkere mā te tikanga tika.
(2) Kore-paheketanga
Me tatau te koki ina whakamahia te kohu. Ka whiwhihia te koki mā te whakauru tere koki. Engari, ka kohia te nekeneke i muri i te wā roa, ā, ka nui haere te hapa. I te nuinga o te wā, mō te tono urupare tere (mō te wā poto), he nui te pānga o te haruru ki te pūnaha. Heoi anō, mō te tono whakatere (mō te wā roa), he nui te pānga o te nekeneke kore ki te pūnaha.
(3)Tauine tauine (tauine tauine)
Ko te iti o te hapa tauine, ko te tika ake o te hua ine.
Kei roto i te "Silicon Valley" o Haina a Beijing Rofea Optoelectronics Co., Ltd. – Beijing Zhongguancun, he umanga hangarau teitei e whakatapua ana ki te mahi ki ngā whare rangahau o roto me tāwāhi, ngā whare rangahau, ngā whare wānanga me ngā kaimahi rangahau pūtaiao hinonga. Ko te nuinga o tā mātou kamupene he rangahau me te whakawhanake motuhake, te hoahoa, te hanga, te hoko hua optoelectronic, ā, e whakarato ana i ngā otinga auaha me ngā ratonga ngaio, whaiaro mō ngā kairangahau pūtaiao me ngā miihini ahumahi. Whai muri i ngā tau o te auahatanga motuhake, kua hangaia he raupapa hua photoelectric whai rawa me te tino pai, e whakamahia whānuitia ana i roto i ngā umanga ā-rohe, hōia, kawe waka, hiko, pūtea, mātauranga, hauora me ētahi atu ahumahi.
Kei te tumanako mātou ki te mahi tahi me koe!
