Umgaqo kunye nokuhlelwa kwenkungu

(1) umgaqo

Umgaqo wenkungu ubizwa ngokuba yiSagnac effect kwifiziksi. Kwindlela yokukhanya evaliweyo, imisebe emibini yokukhanya evela kumthombo ofanayo wokukhanya iya kuphazamiseka xa idibene kwindawo efanayo yokufumanisa. Ukuba indlela yokukhanya evaliweyo inokujikeleza ngokumalunga nendawo engenamandla, umsebe osasazeka kwicala elihle nelibi uya kuvelisa umahluko kwindlela yokukhanya, ohambelana nesantya se-engile yokujikeleza ephezulu. Isantya se-engile yokujikeleza sibalwa ngokusebenzisa umahluko wesigaba olinganiswa yi-photoelectric detector.

Ukusuka kwifomula, okukhona ubude befayibha bude, kokukhona i-radius yokuhamba ye-optical inkulu, kokukhona ubude be-optical bufutshane. Okukhona isiphumo sokuphazamiseka sibonakala ngakumbi. Ngoko ke okukhona ubukhulu benkungu bubaluleke ngakumbi, kokukhona ukuchaneka kuphezulu. Isiphumo se-Sagnac ngokusisiseko sisiphumo sokuhambelana, esibaluleke kakhulu kuyilo lomswakama.
Umgaqo wenkungu kukuba umqadi wokukhanya uthunyelwa usuka kwityhubhu ye-photoelectric uze udlule kwi-coupler (isiphelo esinye singena kwiindawo ezintathu zokuma). Imiqadi emibini ingena kwiringi ngeendlela ezahlukeneyo ngeringi ize ibuyele kwisangqa esinye ukuze kubekho indawo ehambelanayo. Ukukhanya okubuyayo kubuyela kwi-LED kwaye kubone ubunzulu nge-LED. Umgaqo wenkungu ubonakala ulula, kodwa eyona nto ibalulekileyo yindlela yokususa izinto ezichaphazela indlela yokukhanya yemiqadi emibini—ingxaki ebalulekileyo yinkungu.

Umgaqo we-fiber optic gyroscope

(2) uhlengahlengiso

Ngokomgaqo osebenzayo, ii-fiber optic gyroscopes zinokwahlulwa zibe yi-interferometric fiber optic gyroscope (I-FOG), i-resonant fiber optic gyroscope (R-FOG), kunye ne-stimulated Brillouin scattering fiber optic gyroscope (B-FOG). Okwangoku, i-fiber optic gyroscope evuthiweyo yi-interferometric fiber optic gyroscope (isizukulwana sokuqala se-fiber optic gyroscope), esetyenziswa kakhulu. Isebenzisa i-multi-turn fiber coil ukuphucula isiphumo seSagnac. Kwelinye icala, i-double beam ring interferometer eyenziwe yi-multi-turn single-mode fiber coil inokubonelela ngocoselelo oluphezulu, oluya kwenza lonke ulwakhiwo lube nzima ngakumbi.
Ngokwendlela olujikelezileyo, inkungu ingahlulwa ibe yi-open-loop mist kunye ne-closed-loop FOG. I-open-loop fiber optic gyroscope (Ogg) ineengenelo zesakhiwo esilula, ixabiso eliphantsi, ukuthembeka okuphezulu, kunye nokusetyenziswa kwamandla aphantsi. Kwelinye icala, iingxaki ze-Ogg kukungangeni kakuhle komgca wokufaka kunye nokukhupha kunye nobubanzi obuncinci obuguqukayo. Ke ngoko, isetyenziswa kakhulu njenge-angle sensor. Ulwakhiwo olusisiseko lwe-open-loop IFOG yi-ring double-beam interferometer. Ngenxa yoko, isetyenziswa ikakhulu kwimeko yokuchaneka okuphantsi kunye nomthamo omncinci.
Isalathisi sokusebenza kwenkungu
Inkungu isetyenziswa kakhulu ukulinganisa isantya se-angular, kwaye naluphi na umlinganiselo luyimpazamo.

(1) ingxolo

Indlela yomsindo wenkungu igxile kakhulu kwicandelo lokufumanisa i-optical okanye i-photoelectric, elimisela ubuncinci bokuvakalelwa kokufuma. Kwi-fiber-optic gyroscope (FOG), ipharamitha ebonisa ingxolo emhlophe ephumayo yesantya se-angular yi-random walk coefficient ye-detection bandwidth. Kwimeko yengxolo emhlophe kuphela, inkcazo ye-random walk coefficient ingenziwa lula njengomlinganiselo wozinzo lwe-bias olulinganisiweyo kwiingcambu zesikwere ze-detection bandwidth kwi-bandwidth ethile.

Ukuba kukho ezinye iintlobo zengxolo okanye ukushukuma, sidla ngokusebenzisa uhlalutyo luka-Allan lwe-variance ukuze sifumane i-random walk coefficient ngendlela efanelekileyo.

(2) Akukho kushukuma

Ukubalwa kwee-engile kuyafuneka xa kusetyenziswa inkungu. I-engile ifunyanwa ngokudityaniswa kwesantya se-angular. Ngelishwa, ukushukuma kuyaqokelelwa emva kwexesha elide, kwaye impazamo iya isiba nkulu ngakumbi nangakumbi. Ngokubanzi, kwisicelo sempendulo ekhawulezayo (sexesha elifutshane), ingxolo inefuthe elikhulu kwinkqubo. Sekunjalo, kwisicelo sokuhamba (sexesha elide), ukushukuma okungekho ngxaki kunempembelelo enkulu kwinkqubo.

(3)Isikali (isikali)

Okukhona impazamo ye-scale factor incinci, kokukhona isiphumo sokulinganisa sichanekile.
