Nheyo uye kupatsanurwa kwemhute

(1) musimboti

Nheyo yemhute inonzi Sagnac effect mufizikisi. Munzira yechiedza chakavharwa, mwenje miviri yechiedza inobva kuchiedza chimwe chete inokanganiswa kana yakabatana panzvimbo imwe chete yekuona. Kana nzira yechiedza chakavharwa iine kutenderera kwakaenzana nenzvimbo isina simba, mwenje unopararira munzira dzakanaka nedzisina kunaka uchaburitsa musiyano wenzira yechiedza, zvinoenderana nekumhanya kwekona yekutenderera kwepamusoro. Kumhanya kwekona yekutenderera kunoverengerwa uchishandisa musiyano wechikamu unoyerwa ne photoelectric detector.

Kubva pafomura, kureba kwefiber, kureba kwe optical walking radius, kupfupika kwe optical wavelength. Kana kupindirana kwacho kuchinyanya kuoneka. Saka kana huwandu hwemhute huchikosha, kunyatsojeka kwacho kunowedzera. Sagnac effect inonyanya kureva relativistic effect, iyo yakakosha zvikuru pakugadzira hunyoro.
Nheyo yemhute ndeyekuti mwenje wechiedza unotumirwa kubva muchubhu ye photoelectric wopfuura nepakati pe coupler (mugumo mumwe unopinda munzvimbo nhatu). Matanda maviri anopinda mu ring nenzira dzakasiyana kuburikidza ne ring uye obva adzoka akatenderera denderedzwa rimwe chete kuti aonekwe zvakanaka. Mhepo inodzoka inodzokera ku LED uye inoona kusimba kwayo kuburikidza ne LED. Nheyo yemhute inoita seiri nyore, asi chinhu chakakosha ndechekuti ungabvisa sei zvinhu zvinokanganisa nzira ye optical yematanda maviri - dambudziko guru riri mhute.

Nheyo ye fiber optic gyroscope

(2) kupatsanura

Zvichienderana nepfungwa yekushanda, fiber optic gyroscopes inogona kukamurwa kuita interferometric fiber optic gyroscope (I-FOG), resonant fiber optic gyroscope (R-FOG), uye stimulated Brillouin scattering fiber optic gyroscope (B-FOG). Parizvino, fiber optic gyroscope yakakura ndiyo interferometric fiber optic gyroscope (chizvarwa chekutanga fiber optic gyroscope), iyo inoshandiswa zvakanyanya. Inoshandisa multi-turn fiber coil kuti iwedzere Sagnac effect. Kune rumwe rutivi, double beam ring interferometer inoumbwa ne multi-turn single-mode fiber coil inogona kupa kunyatsojeka, izvo zvichaita kuti chimiro chose chive chakaoma.
Zvichienderana nerudzi rwe loop, fog inogona kukamurwa kuita open-loop mhute uye closed-loop FOG. Open-loop fiber optic gyroscope (Ogg) ine zvakanakira zvechimiro chiri nyore, mutengo wakaderera, kuvimbika kwakanyanya, uye kushandiswa kwesimba kushoma. Kune rumwe rutivi, zvakaipa zveOgg i input-output linearity isina kunaka uye dynamic range diki. Saka, inonyanya kushandiswa se angle sensor. Chimiro chikuru che open-loop IFOG i ring double-beam interferometer. Nekuda kweizvozvo, inoshandiswa zvakanyanya mumamiriro ekusanyatsojeka uye vhoriyamu diki.
Chiratidzo chekushanda kwemhute
Mhute inonyanya kushandiswa kuyera kumhanya kwekona, uye chero chipimo chipi zvacho chinenge chiri chikanganiso.

(1) ruzha

Maitiro eruzha rwemhute anonyanya kutaurwa muchikamu chekuona optical kana photoelectric, icho chinosarudza kunzwisisika kushoma kwehunyoro. Mu fiber-optic gyroscope (FOG), parameter inoratidza ruzha rwemhute rwemhute rwe angular ndiyo random walk coefficient ye detection bandwidth. Kana paine ruzha rwemhute chete, tsananguro ye random walk coefficient inogona kurerutswa sechiyero chekugadzikana kwe bias yakayerwa kune square root ye detection bandwidth mune imwe bandwidth.

Kana paine mamwe marudzi eruzha kana kusvetuka, tinowanzo shandisa ongororo yaAllan yevariance kuti tiwane random walk coefficient nenzira chaiyo.

(2) Kusafamba-famba zvachose

Kuverenga makona kunodiwa kana uchishandisa mhute. Koni inowanikwa nekubatanidza kwe angular velocity. Zvinosuwisa kuti kusvetuka kunounganidzwa mushure menguva yakareba, uye kukanganisa kuri kuramba kuchikura. Kazhinji, pakushandisa nekukurumidza kupindura (kwenguva pfupi), ruzha runokanganisa zvakanyanya sisitimu. Kunyange zvakadaro, pakushandisa kwekufamba (kwenguva refu), zero drift ine simba guru pasisitimu.

(3) Chiyero chechiyero (chiyero chechiyero)

Kana chikanganiso che scale factor chiri chidiki, mhedzisiro yekuyera inenge yakarurama.

Beijing Rofea Optoelectronics Co., Ltd. iri mu "Silicon Valley" yeChina - Beijing Zhongguancun, ikambani yetekinoroji yepamusoro yakatsaurirwa kushandira masangano ekutsvagisa emuno nekunze kwenyika, masangano ekutsvagisa, mayunivhesiti nevashandi vekutsvagisa sainzi vemabhizinesi. Kambani yedu inonyanya kuita tsvakurudzo yakazvimirira nekugadzira, dhizaini, kugadzira, kutengesa zvigadzirwa zve optoelectronic, uye inopa mhinduro itsva uye masevhisi ehunyanzvi, akagadzirirwa vaongorori vesainzi nemainjiniya emaindasitiri. Mushure memakore ekuvandudza kwakazvimirira, yakagadzira nhevedzano yakapfuma uye yakakwana yezvigadzirwa zve photoelectric, izvo zvinoshandiswa zvakanyanya mumaindasitiri emaguta, emauto, ekufambisa, emagetsi, emari, dzidzo, ekurapa nedzimwe nzvimbo.
