Ihame n'ishyirwa mu byiciro ry'igihu

(1) ihame

Ihame ry'igihu ryitwa ingaruka za Sagnac muri fiziki. Mu nzira y'urumuri ifunze, imirasire ibiri y'urumuri ituruka ku isoko imwe y'urumuri izavangwa iyo ihujwe n'aho iboneka. Iyo inzira y'urumuri ifunze ifite uruziga ugereranije n'umwanya udafite aho ugarukira, uruziga rukwirakwira mu cyerekezo cyiza n'ikibi ruzatanga itandukaniro ry'inzira y'urumuri, ringana n'umuvuduko w'inguni yo hejuru y'uruziga. Umuvuduko w'inguni uzunguruka ubarwa hakoreshejwe itandukaniro ry'icyiciro ryapimwe na detector y'amashanyarazi.

Ukurikije formula, uko uburebure bwa fibre burushaho kuba burebure, ni ko n'uburebure bw'urumuri rw'amazi burushaho kuba bunini, ni ko n'uburebure bw'urumuri rw'amazi burushaho kuba bugufi. Uko ingaruka zo kubangamira zigaragara cyane. Bityo, uko ingano y'igihu irushaho kuba nini, ni ko ubwiza burushaho kwiyongera. Ingaruka za Sagnac muri rusange ni ingaruka zishingiye ku miterere y'amazi, ikaba ari ingenzi cyane mu gushushanya ubushuhe.
Ihame ry'igihu ni uko urumuri rwoherezwa mu muyoboro w'amashanyarazi unyuze mu gice gihuza (impande imwe yinjirira ahantu hatatu). Imirasire ibiri yinjira mu mpande zitandukanye binyuze mu mpande hanyuma ikagaruka ku ruziga rumwe kugira ngo ihuzwe neza. Urumuri rugaruka rugaruka kuri LED kandi rukamenya ubukana bwa LED. Ihame ry'igihu risa n'aho ryoroshye, ariko icy'ingenzi ni uburyo bwo gukuraho ibintu bigira ingaruka ku nzira y'urumuri rw'imirasire ibiri—ikibazo cy'ibanze ni igihu.

Ihame rya gyroscope ya fiber optic

(2) gushyira mu byiciro

Dukurikije ihame ry'imikorere, gyroscope za fiber optic zishobora kugabanywamo interferometric fiber optic gyroscope (I-FOG), resonant fiber optic gyroscope (R-FOG), na stimulated Brillouin scattering fiber optic gyroscope (B-FOG). Kuri ubu, gyroscope ya fiber optic ikuze cyane ni interferometric fiber optic gyroscope (gyroscope ya fiber optic yo mu gisekuru cya mbere), ikoreshwa cyane. Ikoresha multi-turn fiber coil kugira ngo yongere Sagnac effect. Ku rundi ruhande, interferometer ifite double beam ring igizwe na multi-turn single-mode fiber coil ishobora gutanga ubuziranenge bwo hejuru, bizatuma imiterere yose iba igoye cyane.
Dukurikije ubwoko bw'umuyoboro, igihu gishobora kugabanywamo ibihu bifunguye n'ibihu bifunze. Gyroscope ya fiber optic (Ogg) ifite ibyiza byoroshye, igiciro gito, kwizera cyane, no gukoresha ingufu nke. Ku rundi ruhande, ingaruka mbi za Ogg ni umurongo mubi w'ibisohoka n'ibisohoka ndetse n'urwego ruto rw'ingufu. Kubwibyo, ikoreshwa cyane cyane nk'icyuma gipima inguni. Imiterere y'ibanze ya IFOG ni interferometer ifite uruziga runini. Kubera iyo mpamvu, ikoreshwa cyane cyane mu gihe nta buhanga burimo kandi nta bunini buhagije ifite.
Igipimo cy'imikorere y'igihu
Igihu gikoreshwa cyane cyane mu gupima umuvuduko w'inguni, kandi igipimo icyo ari cyo cyose kiba ari ikosa.

(1) urusaku

Uburyo urusaku rw'igihu rwibanda cyane cyane mu gice cyo gutahura urumuri cyangwa amashanyarazi, ari na cyo kigena ubushobozi bwo gutahura ubushuhe buke cyane. Muri gyroscope ya fiber-optic (FOG), igipimo kigaragaza urusaku rw'umweru rusohoka rw'igipimo cy'inguni ni igipimo cyo kugenda mu buryo butunguranye cya bandwidth yo gutahura. Mu gihe cy'urusaku rw'umweru gusa, ibisobanuro bya gipimo cyo kugenda mu buryo butunguranye bishobora koroshywa nk'igipimo cy'ubudahangarwa bwa bias bupimwe n'umuzi kare wa bandwidth yo gutahura mu mpande runaka.

Iyo hari ubundi bwoko bw'urusaku cyangwa guhindagurika kw'amazi, dukoresha isesengura rya Allan ry'impinduka kugira ngo tubone igipimo cy'urugendo rudasobanutse dukoresheje uburyo bukwiye.

(2) Nta guhindagurika kw'ibintu

Kubara inguni birakenewe iyo ukoresha igihu. Inguni iboneka hakoreshejwe uburyo bwo guhuza umuvuduko w'inguni. Ikibabaje ni uko ubwikorezi bukomeza kwiyongera nyuma y'igihe kirekire, kandi ikosa rigenda rirushaho kwiyongera. Muri rusange, ku ikoreshwa ryihuse ryo gusubiza (igihe gito), urusaku rugira ingaruka zikomeye kuri sisitemu. Nyamara, ku ikoreshwa ryo kuyobora (igihe kirekire), ubwikorezi ntarengwa bugira ingaruka zikomeye kuri sisitemu.

(3) Igipimo cy'umunzani (igipimo cy'umunzani)

Uko ikosa ry'ibipimo rito rihinduka, ni ko ibisubizo byo gupima biba byiza kurushaho.

Beijing Rofea Optoelectronics Co., Ltd. iherereye mu "Silicon Valley" mu Bushinwa - Beijing Zhongguancun, ni ikigo cy’ikoranabuhanga rigezweho cyihaye inshingano zo gukorera ibigo by’ubushakashatsi byo mu gihugu no mu mahanga, ibigo by’ubushakashatsi, za kaminuza n’abakozi b’ubushakashatsi bwa siyansi mu bigo. Isosiyete yacu ikora cyane cyane ubushakashatsi bwigenga n’iterambere, gushushanya, gukora, kugurisha ibicuruzwa bya optoelectronic, kandi itanga ibisubizo bishya na serivisi z’umwuga ku bashakashatsi ba siyansi n’abahanga mu nganda. Nyuma y’imyaka myinshi y’udushya twigenga, yakoze urukurikirane rw’ibicuruzwa bikungahaye kandi byuzuye by’amashanyarazi, bikoreshwa cyane mu nganda z’umujyi, iza gisirikare, ubwikorezi, ingufu z’amashanyarazi, imari, uburezi, ubuvuzi n’izindi nganda.
