Nheyo uye kupatsanurwa kwemhute

(1) mutemo

Musimboti wemhute unonzi Sagnac mhedzisiro mufizikisi.Mugwara rechiedza rakavharwa, mirazvo miviri yechiedza kubva kune imwe mwenje sosi inozokanganiswa kana ichinge yasanganisirwa kunzvimbo imwechete yekuona.Kana nzira yechiedza yakavharwa iine kutenderera kunoenderana nenzvimbo inertial, danda rinopararira munzira yakanaka nerakaipa rinoburitsa mutsauko wenzira yechiedza, inoenzana nevelocity yekona yekutenderera kwepamusoro.Iko kutenderera kwekona velocity inoverengerwa nekushandisa mutsauko wechikamu wakayerwa nephotoelectric detector.

Kubva pafomula, kureba kwefaibha kureba, iyo yakakura iyo optical yekufamba radius, ipfupi yeoptical wavelength.Iyo inonyanya kuoneka iyo yekukanganisa mhedzisiro ndeye.Saka iyo inonyanya kukosha huwandu hwemhute, iyo inokwirisa iyo chaiyo.Sagnac mhedzisiro ndeye relativistic mhedzisiro, iyo yakakosha pakugadzirwa kwehunyoro.
Nheyo yemhute ndeyokuti danda rechiedza rinotumirwa kubva paphotoelectric chubhu uye richipfuura nepakati pe coupler (imwe mugumo inopinda katatu).Matanda maviri anopinda murin'i nenzira dzakasiyana kuburikidza nerin'i yozodzoka kutenderedza denderedzwa rimwechete kuti anyatsopindirana.Chiedza chakadzoka chinodzokera ku LED uye chinoona kusimba kuburikidza ne LED.Nheyo yemhute inoita seyakapusa, asi chinonyanya kukosha ndechekubvisa sei zvinhu zvinokanganisa nzira yekuona yematanda maviri-dambudziko rakakura kuve mhute.

Nheyo ye fiber optic gyroscope

(2) classification

Zvinoenderana nemusimboti wekushanda, fiber optic gyroscopes inogona kukamurwa kuita interferometric fiber optic gyroscope (I-FOG), resonant fiber optic gyroscope (R-FOG), uye yakakurudzira Brillouin kuparadzira fiber optic gyroscope (B-FOG).Parizvino, iyo yakanyanya kukura fiber optic gyroscope ndiyo interferometric fiber optic gyroscope (yekutanga chizvarwa fiber optic gyroscope), iyo inoshandiswa zvakanyanya.Inoshandisa multi-turn fiber coil kuwedzera iyo Sagnac mhedzisiro.Kune rumwe rutivi, interferometer yakapetwa kaviri danda inoumbwa ne-multi-turn single-mode fiber coil inogona kupa yakanyatsojeka, iyo ichaita kuti chimiro chese chiwedzere kuoma.
Zvinoenderana nerudzi rwe loop, mhute inogona kukamurwa kuita yakavhurika-loop mhute uye yakavharwa-loop FOG.Iyo yakavhurika-loop fiber optic gyroscope (Ogg) ine zvakanakira chimiro chakareruka, mutengo wakaderera, kuvimbika kwakanyanya, uye kuderera kwesimba rekushandisa.Kune rimwe divi, izvo zvisingabatsiri zveOgg hazvina kunaka kupinza-kubuda mutsara uye diki ine simba renji.Naizvozvo, inonyanya kushandiswa senge angle sensor.Iyo yakakosha chimiro cheiyo yakavhurika-loop IFOG irin'i kaviri-beam interferometer.Nekuda kweizvozvo, inoshandiswa zvakanyanya mumamiriro ekushomeka kwakaderera uye vhoriyamu diki.
Performance index of fog
Fog inonyanya kushandiswa kuyera angular velocity, uye chero kuyerwa iko kukanganisa.

(1)ruzha

Iyo ruzha meshini yemhute inonyanya kunyudzwa mune yekuona kana photoelectric yekuona chikamu, iyo inotaridza kushoma kunoonekwa kunzwisiswa kwehunyoro.Mu fiber-optic gyroscope (FOG), parameter inoratidza kubuda kweruzha ruchena rweangular rate ndiyo yakasarudzika yekufamba coefficient yeinoona bandwidth.Panyaya yeruzha ruchena chete, tsananguro yekufamba zvisina tsarukano coefficient inogona kurerutswa seyero yeyero yakayerwa bias kugadzikana kune yakaenzana midzi yeiyo yekuona bandwidth mune imwe bandwidth.

Kana paine mamwe marudzi eruzha kana kukukurwa, tinowanzo shandisa ongororo yaAllan yemutsauko kuti tiwane nhanho yekufamba nenzira kwayo.

(2)Zero kukukurwa

Angle calculation inodiwa kana uchishandisa fog.Iko kona inowanikwa neangular velocity integration.Nehurombo, kudonha kunounganidzwa mushure menguva refu, uye kukanganisa kuri kuramba kuchikura.Kazhinji kutaura, yekukurumidza kupindura application (nguva pfupi), ruzha runonyanya kukanganisa sisitimu.Zvakadaro, yekufambisa application (yenguva refu), zero Drift ine simba rakakura pane system.

(3)Chikero chinhu (chikero chinhu)

Iyo idiki iyo chikero chechinhu chikanganiso chiri, ndiko kuwedzera kwakaringana mhedzisiro yekuyera.

Beijing Rofea Optoelectronics Co., Ltd. iri muChina "Silicon Valley" - Beijing Zhongguancun, ibhizimusi repamusoro-soro rakatsaurirwa kushandira masangano ekutsvagisa epamba nekunze, masangano ekutsvagisa, mayunivhesiti uye bhizinesi vashandi vezvesainzi.Kambani yedu inonyanya kuita mukutsvagisa yakazvimirira uye kusimudzira, dhizaini, kugadzira, kutengesa kwezvigadzirwa zveoptoelectronic, uye inopa mhinduro nyowani uye nehunyanzvi, masevhisi emunhu evaongorori vesainzi uye mainjiniya emaindasitiri.Mushure memakore ekuzvimiririra innovation, yakagadzira akapfuma uye akakwana akatevedzana ezvigadzirwa zvemafotoelectric, ayo anoshandiswa zvakanyanya mumaspala, mauto, zvekufambisa, simba remagetsi, mari, dzidzo, zvekurapa uye mamwe maindasitiri.
