1, Ingqikelelo esisiseko yefiber optic gyroscope
I-fiber optic gyroscope yanamhlanje sisixhobo esinokuqinisekisa ngokuchanekileyo ukuqhelaniswa kwezinto ezihambayo, sisixhobo sokuhamba nge-inertial esisetyenziswa kakhulu kwi-aviation yanamhlanje, ukuhamba, i-aerospace kunye neshishini lokhuselo, uphuhliso lwayo lubaluleke kakhulu ukubaluleka kweqhinga kwishishini lelizwe, ukhuselo lwelizwe. kunye nolunye uphuhliso lobuchwepheshe obuphezulu.
2. Inkcazo yefiber optic gyro
I-Fiber optic gyroscope yinto enovakalelo esekwe kwiikhoyili zefiber optical.Ukukhanya okuphuma kwi-laser diode kwanda kumacala amabini ecaleni kwefiber optical.Umahluko wendlela yokusasaza ukukhanya umisela ukufuduswa kwe-angular yento enovakalelo.
Iingenelo ze-fiber optic gyroscope xa kuthelekiswa ne-gyroscope yomatshini yemveli zonke zikwimeko eyomeleleyo, akukho malungu ajikelezayo kunye neenxalenye zokukhuhlana, ubomi obude, uluhlu olukhulu oluguquguqukayo, ukuqala kwangoko, ubume obulula, ubungakanani obuncinci kunye nobunzima obulula.Xa kuthelekiswa ne-laser gyroscope, i-fiber optic gyroscope ayinayo ingxaki ye-latching kwaye ayifuni umatshini ochanekileyo wendlela ye-optical block kwi-quartz block, ngoko ke ixabiso liphantsi.
3, iFiber optic gyro umgaqo osisiseko wokusebenza
Ukuphunyezwa kwe-fiber optic gyroscope isekelwe ikakhulu kwi-theory ye-Segnick: xa ukukhanya okukhanyayo kuhamba kwijelo elimise okwesangqa, ukuba umjelo wendandatho ngokwawo unesantya sokujikeleza, ngoko ixesha elifunekayo ukuze ukukhanya kuhambe kwicala lokukhanya. ukujikeleziswa kwetshaneli kungaphezulu kwexesha elifunekayo ukuhamba kwelinye icala lalo kujikeleziswa kwejelo.Oku kuthetha ukuba xa i-loop optical ijikelezayo, uluhlu lokukhanya lwe-optical loop lutshintsha kwiindlela ezahlukeneyo zokuhamba ngokubhekiselele kuluhlu lokukhanya lwe-loop ekuphumleni.Ukusebenzisa olu tshintsho kuluhlu lwe-optical, umehluko wesigaba phakathi kwee-loops ezimbini ze-optical okanye utshintsho kwi-interference fringe ifunyenwe, kwaye i-angular velocity ye-optical loop rotation inokulinganiswa, oko ngumgaqo osebenzayo we-fiber optic gyroscope.
4,Intshayelelo yethiyori kaSegnick
Ithiyori yeSeignik ithi xa isibane sokukhanya sihambela phambili kwiluphu, ukuba iluphu ngokwayo inesantya sokujikeleza, ngoko kuthatha ixesha elingakumbi ukuba ukukhanya kuqhubele phambili kwicala lokujikeleza kweluphu kunokuqhubela phambili kwelinye. isalathiso sokujikeleza kwe-loop.
Oku kuthetha ukuba xa i-loop optical ijikeleza, uluhlu lokukhanya lwe-optical loop lutshintsha kwiindlela ezahlukeneyo eziya phambili ngokubhekiselele kuluhlu lokukhanya lwe-loop ekuphumleni.Ngokusebenzisa olu tshintsho kuluhlu lwe-optical, ukuba ukuphazamiseka kuveliswa phakathi kokukhanya okuhamba phambili kwiindlela ezahlukeneyo zokulinganisa isantya sokujikeleza kwe-loop, i-interferometric fiber optic gyroscope inokudalwa.Ukuba usebenzisa olu tshintsho kwindlela ye-optical ye-loop ukufezekisa ukuphazamiseka phakathi kokukhanya okujikelezayo kwi-loop, oko kukuthi, ngokulungelelanisa i-resonant frequency yokukhanya kwi-fiber optical loop kunye nokulinganisa isantya sokujikeleza kwe-loop, i-resonant fiber optic gyroscope inokuveliswa.
