Isimiso kanye nokuhlukaniswa kwenkungu

(1) isimiso

Isimiso senkungu sibizwa ngokuthi umphumela we-Sagnac ku-physics. Endleleni yokukhanya evaliwe, imisebe emibili yokukhanya evela emthonjeni ofanayo izophazanyiswa lapho ihlanganiswa endaweni efanayo yokuthola. Uma indlela yokukhanya evaliwe inokujikeleza okuhlobene nesikhala esingenasici, umsebe osakazeka eziqondisweni ezinhle nezimbi uzokhiqiza umehluko wendlela yokukhanya, okulingana nejubane le-engeli yokujikeleza ephezulu. Ijubane le-engeli yokujikeleza libalwa ngokusebenzisa umehluko wesigaba olinganiswa ngumtshina we-photoelectric.

Kusukela kufomula, uma ubude befayibha bude, i-radius yokuhamba ye-optical inkulu, i-wavelength ye-optical imfushane. Uma umphumela wokuphazamiseka ubonakala kakhulu. Ngakho-ke uma ivolumu yenkungu ibaluleke kakhulu, kulapho ukunemba kuphakama khona. Umphumela we-Sagnac empeleni uwumphumela wokuhlobana, okubaluleke kakhulu ekwakhiweni komswakama.
Isimiso senkungu ukuthi umsebe wokukhanya uthunyelwa usuka epayipini le-photoelectric bese udlula ku-coupler (uhlangothi olulodwa lungena ezitobhini ezintathu). Imishayo emibili ingena endandatho ngezindlela ezahlukene ngendandatho bese ibuya izungeze indilinga eyodwa ukuze ibekwe kahle. Ukukhanya okubuyiselwayo kubuyela ku-LED futhi kubone ubukhali nge-LED. Isimiso senkungu sibonakala silula, kodwa into ebaluleke kakhulu ukuthi ungasusa kanjani izici ezithinta indlela yokukhanya yemishayo emibili—inkinga eyisisekelo ukuba inkungu.

Isimiso se-fiber optic gyroscope

(2) ukuhlukaniswa

Ngokomgomo wokusebenza, ama-gyroscope e-fiber optic angahlukaniswa abe yi-interferometric fiber optic gyroscope (I-FOG), i-resonant fiber optic gyroscope (R-FOG), kanye ne-stimulated Brillouin scattering fiber optic gyroscope (B-FOG). Njengamanje, i-fiber optic gyroscope evuthiwe kakhulu yi-interferometric fiber optic gyroscope (isizukulwane sokuqala se-fiber optic gyroscope), esetshenziswa kabanzi. Isebenzisa i-multi-turn fiber coil ukuthuthukisa umphumela we-Sagnac. Ngakolunye uhlangothi, i-double beam ring interferometer eyakhiwe yi-multi-turn single-mode fiber coil inganikeza ukunemba okuphezulu, okuzokwenza isakhiwo sonke sibe nzima kakhulu.
Ngokohlobo lwe-loop, inkungu ingahlukaniswa ibe yi-open-loop mist kanye ne-closed-loop FOG. I-open-loop fiber optic gyroscope (Ogg) inezinzuzo zesakhiwo esilula, intengo ephansi, ukuthembeka okuphezulu, kanye nokusetshenziswa kwamandla aphansi. Ngakolunye uhlangothi, izinkinga ze-Ogg ukuhleleka kokufaka-ukukhipha okubi kanye nobubanzi obuncane obuguquguqukayo. Ngakho-ke, isetshenziswa kakhulu njengenzwa ye-angle. Isakhiwo esiyisisekelo se-open-loop IFOG iyi-interferometer eyindandatho ephindwe kabili. Ngenxa yalokho, isetshenziswa ikakhulukazi esimweni sokunemba okuphansi kanye nevolumu encane.
Inkomba yokusebenza kwenkungu
Inkungu isetshenziswa kakhulu ukukala ijubane le-angular, futhi noma yikuphi ukulinganisa kuyiphutha.

(1) umsindo

Indlela yomsindo wenkungu igxile kakhulu engxenyeni yokuthola i-optical noma i-photoelectric, enquma ukuzwela okuncane okubonakalayo komswakama. Ku-gyroscope ye-fiber-optic (i-FOG), ipharamitha echaza umsindo omhlophe ophumayo wesilinganiso se-angular yi-coefficient yokuhamba engahleliwe ye-bandwidth yokuthola. Endabeni yomsindo omhlophe kuphela, incazelo ye-coefficient yokuhamba engahleliwe ingenziwa lula njengesilinganiso sokuqina kwe-bias okulinganisiwe kumsuka wesikwele we-bandwidth yokuthola ku-bandwidth ethile.

Uma kunezinye izinhlobo zomsindo noma ukukhukhuleka, sivame ukusebenzisa ukuhlaziywa kuka-Allan kokuhlukahluka ukuze sithole i-random walk coefficient ngendlela efanele.

(2) Ukuzulazula okungenalutho

Kudingeka ukubalwa kwe-engela uma usebenzisa inkungu. I-engela itholakala ngokuhlanganiswa kwejubane le-engela. Ngeshwa, ukukhukhuleka kuqongelela ngemva kwesikhathi eside, futhi iphutha liya likhula. Ngokuvamile, kuhlelo lokusebenza lokuphendula okusheshayo (isikhathi esifushane), umsindo uthinta kakhulu uhlelo. Noma kunjalo, kuhlelo lokusebenza lokuzulazula (isikhathi eside), ukukhukhuleka okungu-zero kunethonya elikhulu ohlelweni.

(3)Isici sesikali (isici sesikali)

Uma iphutha lesici sesikali lincane, umphumela wokulinganisa unembile kakhulu.

I-Beijing Rofea Optoelectronics Co., Ltd. etholakala “eSigodini saseSilicon” saseShayina – i-Beijing Zhongguancun, iyibhizinisi lobuchwepheshe obuphezulu elizinikele ekukhonzeni izikhungo zocwaningo zasekhaya nezangaphandle, izikhungo zocwaningo, amanyuvesi kanye nabasebenzi bocwaningo lwesayensi yebhizinisi. Inkampani yethu ihileleke kakhulu ocwaningweni oluzimele kanye nentuthuko, ukuklama, ukukhiqiza, ukuthengisa imikhiqizo ye-optoelectronic, futhi inikeza izixazululo ezintsha kanye nezinsizakalo zobungcweti, ezenzelwe wena kubacwaningi besayensi kanye nonjiniyela bezimboni. Ngemva kweminyaka eminingi yokusungula izinto ezintsha, yakhe uchungechunge olucebile noluphelele lwemikhiqizo ye-photoelectric, esetshenziswa kabanzi embonini kamasipala, yezempi, yezokuthutha, yamandla kagesi, yezezimali, yezemfundo, yezokwelapha kanye neminye imboni.
