Isimiso nokuhlukaniswa kwenkungu

Isimiso nokuhlukaniswa kwenkungu

(1)isimiso

Umgomo wenkungu ubizwa ngokuthi umphumela we-Sagnac ku-physics. Endleleni yokukhanya evaliwe, amalambu amabili okukhanya avela emthonjeni ofanayo wokukhanya azophazanyiswa lapho ehlanganiswa endaweni efanayo yokutholwa. Uma indlela yokukhanya evaliwe inokuzungezisa okuhlobene nesikhala esingenalutho, i-beam esakazeka eziqondisweni ezinhle nezingezinhle izoveza umehluko wendlela yokukhanya, okulingana nesivinini se-engeli yokuzungeza ephezulu. Isivinini se-engeli yokuzungezisa sibalwa kusetshenziswa umehluko wesigaba olinganiswa ngomtshina wesithombe sikagesi.

Kusukela kufomula, ubude befiber ubude, irediyasi yokuhamba ebonakalayo inkulu, iba mfishane ubude begagasi obubonakalayo. Umphumela wokuphazamiseka ubonakala kakhulu. Ngakho-ke lapho ivolumu yenkungu ibaluleke kakhulu, iphezulu ukunemba. Umphumela we-Sagnac empeleni uwumphumela we-relativistic, obaluleke kakhulu ekwakhiweni komswakama.
Umgomo wenkungu ukuthi umsebe wokukhanya uthunyelwa ngaphandle kweshubhu le-photoelectric futhi udlule ku-coupler (umkhawulo owodwa ungena ezindaweni ezintathu). Imishayo emibili ingena eringini ngezindlela ezihlukene ngendandatho bese ibuyela endingilizini eyodwa ukuze ithole indawo ephezulu ehlangene. Ukukhanya okubuyisiwe kubuyela ku-LED futhi kuthola ukushuba nge-LED. Isimiso senkungu sibonakala silula, kodwa into ebaluleke kakhulu indlela yokuqeda izici ezithinta indlela ye-optical yemishayo emibili-inkinga eyisisekelo yokuba yinkungu.

Isimiso se-fiber optic gyroscope

(2)ukwahlukanisa

Ngokuvumelana nesimiso sokusebenza, i-fiber optic gyroscopes ingahlukaniswa ibe yi-interferometric fibre optic gyroscope (I-FOG), i-resonant fibre optic gyroscope (R-FOG), kanye ne-Brillouin evuselelwe ehlakaza i-fiber optic gyroscope (B-FOG). Njengamanje, i-fiber optic gyroscope evuthiwe kakhulu i-fiber optic gyroscope ye-interferometric (isizukulwane sokuqala se-fiber optic gyroscope), esetshenziswa kakhulu. Isebenzisa ikhoyili ye-fiber eshintshashintshayo ukuze ithuthukise umphumela we-Sagnac. Ngakolunye uhlangothi, i-interferometer yendandatho ephindwe kabili eyenziwe nge-multi-turn single-mode fiber coil inganikeza ukunemba okuphezulu, okuzokwenza sonke isakhiwo sibe nzima nakakhulu.
Ngokohlobo lweluphu, inkungu ingahlukaniswa ibe yinkungu evulekile neyiluphu evaliwe. I-open-loop fibre optic gyroscope (Ogg) inezinzuzo zesakhiwo esilula, intengo ephansi, ukwethembeka okuphezulu, nokusetshenziswa kwamandla okuphansi. Ngakolunye uhlangothi, ububi be-Ogg wumugqa wokukhiphayo ompofu kanye nebanga elincane eliguqukayo. Ngakho-ke, isetshenziswa ngokuyinhloko njengenzwa ye-engeli. Isakhiwo esiyisisekelo se-Open-loop IFOG iyi-interferometer eyindandatho ephindwe kabili. Ngenxa yalokho, isetshenziswa ngokuyinhloko esimweni sokunemba okuphansi kanye nevolumu encane.
Inkomba yokusebenza yenkungu
Inkungu isetshenziswa kakhulu ukukala isivinini se-angular, futhi noma isiphi isilinganiso siyiphutha.

(1)umsindo

Indlela yomsindo wenkungu igxile kakhulu engxenyeni yokubona ugesi noma i-photoelectric, enquma ubuncane bokuzwela obubonakalayo bomswakama. Ku-fiber-optic gyroscope (FOG), ipharamitha ekhombisa umsindo omhlophe ophumayo wezinga le-angular yi-coefficient yokuhamba engahleliwe yomkhawulokudonsa otholwayo. Esimeni somsindo omhlophe kuphela, incazelo ye-coefficient yokuhamba okungahleliwe ingenziwa lula njengesilinganiso sokuzinza kokuchema okulinganiselwe kumsuka wesikwele womkhawulokudonsa wokutholwa kumkhawulokudonsa othize.

Uma kukhona ezinye izinhlobo zomsindo noma ukukhukhuleka, ngokuvamile sisebenzisa ukuhlaziya kuka-Allan kokuhluka ukuze sithole i-coefficient yokuhamba okungahleliwe ngendlela efanele.

(2)Zero drift

Ukubalwa kwe-engeli kuyadingeka uma usebenzisa inkungu. I-engeli itholwa ngokuhlanganiswa kwe-angular velocity. Ngeshwa, ukukhukhuleka kuqoqwa ngemva kwesikhathi eside, futhi iphutha liya liba likhulu futhi libe likhulu. Ngokuvamile, kuhlelo lokusebenza lokuphendula ngokushesha (isikhathi esifushane), umsindo uthonya kakhulu uhlelo. Noma kunjalo, kuhlelo lokusebenza lokuzulazula (isikhathi eside), i-zero drift inomthelela omkhulu ohlelweni.

(3)Isici sesikali (isici sesikali)

Iphutha lesici sesikali lincane, umphumela wokulinganisa unembe kakhulu.

I-Beijing Rofea Optoelectronics Co., Ltd. etholakala “eSilicon Valley” yaseChina – Beijing Zhongguancun, iyibhizinisi lobuchwepheshe obuphezulu elizinikele ekuhlinzekeni izikhungo zocwaningo zasekhaya nezangaphandle, izikhungo zocwaningo, amanyuvesi kanye nabasebenzi bocwaningo lwesayensi ebhizinisi. Inkampani yethu ibambe iqhaza kakhulu ocwaningweni nasekuthuthukisweni okuzimele, ukuklama, ukukhiqiza, ukuthengiswa kwemikhiqizo ye-optoelectronic, futhi ihlinzeka ngezixazululo ezintsha nezinsizakalo eziqeqeshiwe, ezenzelwe wena uqobo abacwaningi besayensi nonjiniyela bezimboni. Ngemuva kweminyaka eminingi yokusungula izinto ezizimele, iye yakha uchungechunge olucebile noluphelele lwemikhiqizo ye-photoelectric, esetshenziswa kakhulu kumasipala, ezempi, ezokuthutha, amandla kagesi, ezezimali, ezemfundo, ezokwelapha nezinye izimboni.
