Molao-motheo le lihlopha tsa moholi

(1) molao-motheo

Molao-motheo oa moholi o bitsoa Sagnac effect ho fisiks.Tseleng e koetsoeng ea leseli, mahlaseli a mabeli a tsoang mohloling o le mong oa leseli a tla sitisoa ha a kopana sebakeng se le seng sa ho lemoha.Haeba tsela ea leseli e koetsoeng e na le ho potoloha ho amanang le sebaka sa inertial, sefate se hasang ka litsela tse ntle le tse mpe se tla hlahisa phapang ea tsela e khanyang, e lekanang le lebelo la lebelo le holimo la ho potoloha.The rotation angle velocity e baloa ka ho sebelisa phapano ea phase e lekantsoeng ka photoelectric detector.

Ho tloha ho foromo, bolelele ba fiber bo bolelele, sebaka se seholo sa ho tsamaea sa optical, leqhubu la optical le khutsufala.E hlahelletseng haholo phello ea tšitiso e.Kahoo ha molumo oa moholi o le bohlokoa haholo, o phahamisa ho nepahala.Sagnac ha e le hantle ke phello ea relativistic, e bohlokoa haholo bakeng sa moralo oa mongobo.
Molao-motheo oa moholi ke hore lehlaseli la leseli le romelloa ho tsoa ka har'a tube ea photoelectric 'me le feta ka coupler (qetellong e le' ngoe e kena libakeng tse tharo).Mabala a mabeli a kenya selikalikoe ka litsela tse fapaneng ka selikalikoe ebe a khutlela ho potoloha selikalikoe se le seng bakeng sa superposition e momahaneng.Leseli le khutlang le khutlela ho LED 'me le lemoha matla ka LED.Molao-motheo oa moholi o bonahala o le bonolo, empa ntho ea bohlokoa ka ho fetisisa ke mokhoa oa ho felisa lintlha tse amang tsela ea optical ea maballo a mabeli-bothata ba motheo ba ho ba moholi.

Molao-motheo oa fiber optic gyroscope

(2)karolo

Ho ea ka molao-motheo oa ho sebetsa, li-gyroscopes tsa fiber optic li ka aroloa ka interferometric fiber optic gyroscope (I-FOG), resonant fiber optic gyroscope (R-FOG), le Brillouin e susumetsang e hasanyang fiber optic gyroscope (B-FOG).Hajoale, fiber optic gyroscope e holileng ka ho fetesisa ke interferometric fiber optic gyroscope (moloko oa pele oa fiber optic gyroscope), e sebelisoang haholo.E sebelisa coil ea fiber e feto-fetohang ho ntlafatsa phello ea Sagnac.Ka lehlakoreng le leng, interferometer e nang le marako a mabeli e entsoeng ka mefuta e mengata ea li-fiber coil e ka fana ka ho nepahala ho phahameng, e leng ho tla etsa hore mohaho oohle o be o rarahaneng.
Ho latela mofuta oa lupu, moholi o ka aroloa ka moholi o bulehileng le FOG e koetsoeng.Open-loop fiber optic gyroscope (Ogg) e na le melemo ea sebopeho se bonolo, theko e tlase, ts'epo e phahameng, le tšebeliso e tlase ea matla.Ka lehlakoreng le leng, mefokolo ea Ogg ke mokhoa o fokolang oa tlhahiso-leseling le mefuta e nyane e matla.Ka hona, e sebelisoa haholo-holo e le sensor ea angle.Sebopeho sa motheo sa IFOG e bulehileng-loop ke lesale la li-interferometer tse peli.Ka lebaka leo, e sebelisoa haholo-holo boemong ba ho nepahala ho fokolang le molumo o monyenyane.
Lenane la tshebetso la moholi
Moholi o sebelisoa haholo ho lekanya lebelo la angular, 'me tekanyo efe kapa efe ke phoso.

(1)lerata

Mochine oa lerata oa moholi o tsepamisitsoe haholo karolong ea optical kapa photoelectric discovery, e leng se khethollang bonyane ba kutloisiso ea mongobo.Ho fiber-optic gyroscope (FOG), paramethara e bonts'ang lerata le lesoeu la sekhahla sa sekhahla ke sekhahla sa ho tsamaea se sa reroang sa bandwidth ea ho lemoha.Tabeng ea lerata le lesoeu feela, tlhaloso ea coefficient ea ho tsamaea ka mokhoa o sa reroang e ka nolofatsoa e le karo-karolelano ea botsitso ba leeme bo lekantsoeng ho motso oa lisekoere oa bandwidth ea ho lemoha sebakeng se itseng.

Haeba ho na le mefuta e meng ea lerata kapa ho hoholeha, hangata re sebelisa tlhahlobo ea Allan ea phapang ho fumana coefficient ea ho tsamaea ka mokhoa o nepahetseng.

(2) Ho hoholeha ho se nang letho

Ho baloa ha angle hoa hlokahala ha ho sebelisoa moholi.Sekhutlo se fumanoa ka ho kopanya lebelo la angular.Ka bomalimabe, ho hoholeha ho bokelloa ka mor'a nako e telele, 'me phoso e ntse e eketseha le ho feta.Ka kakaretso, bakeng sa ts'ebeliso ea karabelo e potlakileng (nako e khuts'oane), lerata le ama sistimi haholo.Leha ho le joalo, bakeng sa ts'ebeliso ea ho sesa (nako e telele), zero drift e na le tšusumetso e kholo ho sistimi.
