Ihame no gutondekanya igihu

(1) ihame

Ihame ryigihu ryitwa Sagnac ingaruka muri physics. Mu nzira yumucyo ufunze, imirishyo ibiri yumucyo ituruka kumurongo umwe wumucyo izabangamirwa mugihe ihujwe nikintu kimwe cyo kumenya. Niba inzira yumucyo ifunze ifite kuzenguruka ugereranije nubusumbane bwumwanya, urumuri rukwirakwiza mubyerekezo byiza kandi bibi bizatanga inzira yumucyo itandukaniro, iringaniza numuvuduko wurwego rwo hejuru ruzenguruka. Umuvuduko wo kuzenguruka umuvuduko ubarwa ukoresheje ikinyuranyo cyicyiciro gipimwa nicyuma gifata amashanyarazi.

Uhereye kuri formula, uburebure bwa fibre, nini nini ya optique igenda, niko bigufi uburebure bwa optique. Ikigaragara cyane ingaruka zo kwivanga ni. Nibigaragara cyane ingano yibicu, niko bisobanutse neza. Ingaruka ya Sagnac ningaruka zingirakamaro, ningirakamaro cyane mugushushanya neza.
Ihame ry'igihu ni uko urumuri rw'umucyo rwoherezwa ruva mu miyoboro y'amashanyarazi kandi rukanyura kuri kuperi (impera imwe yinjira ahagarara gatatu). Ibiti bibiri byinjira mu mpeta mu byerekezo bitandukanye binyuze mu mpeta hanyuma ugaruke uzengurutse uruziga rumwe kugirango bihuze. Itara ryagarutse risubira kuri LED kandi ryerekana ubukana binyuze muri LED. Ihame ry'igihu risa naho ryoroshye, ariko icy'ingenzi ni uburyo bwo gukuraho ibintu bigira ingaruka ku nzira nziza y’ibiti bibiri - ikibazo cy’ibanze kuba igihu.

Ihame rya fibre optique giroscope

(2) gushyira mu byiciro

Ukurikije ihame ryakazi, fibre optique giroscopes irashobora kugabanywamo interferometric fibre optique giroscope (I-FOG), resonant fibre optique giroscope (R-FOG), kandi igatera Brillouin ikwirakwiza fibre optique giroscope (B-FOG). Kugeza ubu, fibre optique ya giroscope ikuze cyane ni interferometric fibre optique giroscope (igisekuru cya mbere fibre optique giroscope), ikoreshwa cyane. Ikoresha fibre ihinduranya fibre coil kugirango yongere ingaruka za Sagnac. Kurundi ruhande, impeta ebyiri zometse kuri interterometero igizwe ninshuro nyinshi-imwe ya fibre coil irashobora gutanga ibisobanuro bihanitse, bizatuma imiterere yose igorana.
Ukurikije ubwoko bwa loop, igihu kirashobora kugabanywamo ibicu bifunguye kandi bifunze-FOG. Gufungura-loop fibre optique giroscope (Ogg) ifite ibyiza byuburyo bworoshye, igiciro gito, kwizerwa cyane, no gukoresha ingufu nke. Kurundi ruhande, ibibi bya Ogg ni bibi byinjiza-bisohoka umurongo hamwe nintambwe ntoya. Kubwibyo, ikoreshwa cyane nka sensor sensor. Imiterere shingiro yo gufungura-kuzenguruka IFOG ni impeta ya kabiri-beam interferometero. Kubwibyo, ikoreshwa cyane cyane mubihe byubusobanuro buke nubunini buto.
Imikorere yerekana igihu
Igicu gikoreshwa cyane mugupima umuvuduko winguni, kandi gupima kwose nikosa.

(1) urusaku

Uburyo bw'urusaku rw'ibicu byibanda cyane cyane mu gice cya optique cyangwa ifoto yerekana amashanyarazi, kikaba kigena byibura ubushobozi buke bwo kugaragara neza. Muri fibre-optique giroscope (FOG), ibipimo biranga ibisohoka byera urusaku rwera rwikigereranyo ni coeffisiyoneri yo gutambuka yubusa. Kubireba urusaku rwera gusa, ibisobanuro bya coefficient yo gutambuka birashobora kworoha nkikigereranyo cyo kubogama kubogamye kubipimye kumuzi ya kare ya kwaduka kwagutse mugace runaka.

Niba hari ubundi bwoko bwurusaku cyangwa drift, mubisanzwe dukoresha isesengura rya Allan kubitandukanya kugirango tubone coefficient yo gutambuka kuburyo bukwiye.

(2) Zeru

Kubara inguni birakenewe mugihe ukoresheje igihu. Inguni iboneka no guhuza umuvuduko. Kubwamahirwe, drift yegeranijwe nyuma yigihe kinini, kandi ikosa riragenda riba rinini. Muri rusange, kubisubizo byihuse (igihe gito), urusaku rugira ingaruka kuri sisitemu. Biracyaza, kugendana porogaramu (igihe kirekire), drift zeru igira ingaruka zikomeye kuri sisitemu.

(3) Ikintu gipima (ibintu byerekana)

Gutoya igipimo cyibintu ni, nukuri ibisubizo byo gupima ni.

Beijing Rofea Optoelectronics Co., Ltd iherereye mu Bushinwa “Silicon Valley” - Beijing Zhongguancun, ni ikigo cy’ikoranabuhanga rikomeye cyahariwe gukorera ibigo by’ubushakashatsi mu gihugu no mu mahanga, ibigo by’ubushakashatsi, kaminuza ndetse n’abakozi bashinzwe ubushakashatsi mu bumenyi. Isosiyete yacu ikora cyane cyane mubushakashatsi niterambere byigenga, gushushanya, gukora, kugurisha ibicuruzwa bya optoelectronic, kandi bitanga ibisubizo bishya hamwe na serivise zumwuga, zihariye kubashakashatsi ba siyanse n'abashinzwe inganda. Nyuma yimyaka myinshi yo guhanga udushya, yakoze urutonde rwinshi kandi rwuzuye rwibicuruzwa byamashanyarazi, bikoreshwa cyane mumijyi, igisirikare, ubwikorezi, amashanyarazi, imari, uburezi, ubuvuzi nizindi nganda.
