Li-Ring Laser Gyroscopes (RLGs) li tsoetse pele haholo ho tloha ha li qala, li bapala karolo ea bohlokoa lits'ebetsong tsa sejoale-joale tsa ho sesa le tsa lipalangoang. Sengoliloeng sena se shebana le nts'etsopele, molao-motheo, le ts'ebeliso ea li-RLG, tse totobatsang bohlokoa ba tsona mekhoeng ea ho sesa ea inertial le ts'ebeliso ea tsona mekhoeng e fapaneng ea lipalangoang.
Leeto la Histori la Li-Gyroscopes
Ho tloha ho Khopolo ho ea ho Tsamaiso ea Sejoale-joale
Leeto la li-gyroscopes le qalile ka ho qaptjoa ha gyrocompass ea pele ka 1908 ke Elmer Sperry, ea bitsoang "ntate oa theknoloji ea sejoale-joale ea ho tsamaisa likepe," le Herman Anschütz-Kaempfe. Ho theosa le lilemo, li-gyroscopes li bone ntlafatso e kholo, li ntlafatsa ts'ebeliso ea tsona ea ho tsamaisa likepe le lipalangoang. Lintlafatso tsena li thusitse li-gyroscopes ho fana ka tataiso ea bohlokoa bakeng sa ho tsitsisa lifofane tsa lifofane le ho nolofalletsa ts'ebetso ea ho itsamaisa. Pontšo e hlokomelehang ea Lawrence Sperry ka Phuptjane 1914 e bonts'itse bokhoni ba sefofane sa gyroscopic ka ho tsitsisa sefofane ha a ntse a eme ka kamoreng ea lifofane, a tšoaea tsoelo-pele e kholo ea theknoloji ea autopilot.
Phetoho ho Ring Laser Gyroscopes
Ho iphetola ha lintho ho ile ha tsoela pele ka ho qaptjoa ha laser gyroscope ea pele ka 1963 ke Macek le Davis. Boqapi bona bo bontšitse phetoho ho tloha ho li-gyroscope tsa mochini ho ea ho laser gyros, e fanang ka ho nepahala ho holimo, tlhokomelo e tlase le litšenyehelo tse fokotsehileng. Kajeno, ring laser gyros, haholo ts'ebetsong ea sesole, e laola 'maraka ka lebaka la ts'epahalo le ts'ebetso ea tsona libakeng tseo matšoao a GPS a senyehang.
Molao-motheo oa Ring Laser Gyroscopes
Ho utloisisa Phello ea Sagnac
Ts'ebetso ea mantlha ea li-RLG ke bokhoni ba tsona ba ho tseba hore na ntho e shebane le sebaka sefe. Sena se finyelloa ka phello ea Sagnac, moo ring interferometer e sebelisang mahlaseli a laser a tsamaeang ka litsela tse fapaneng ho pota tsela e koetsoeng. Mokhoa oa tšitiso o entsoeng ke maballo ana o sebetsa e le sebaka se emeng sa litšupiso. Motsamao ofe kapa ofe o fetola bolelele ba tsela ea maballo ana, ho baka phetoho mokhoeng oa tšitiso ho ea ka lebelo la angular. Mokhoa ona o bohlale o lumella li-RLG ho lekanya litšupiso ka nepo e ikhethang ntle le ho itšetleha ka litšupiso tsa kantle.
Likopo ho Navigation le Lipalangoang
Revolutionizing Inertial Navigation Systems (INS)
Li-RLG li thusa ho nts'etsopele ea Inertial Navigation Systems (INS), e leng ea bohlokoa bakeng sa ho tataisa likepe, lifofane le limisaele libakeng tse hanoang ke GPS. Moralo oa bona o kopaneng, o se nang likhohlano o li etsa hore li tšoanelehe bakeng sa lits'ebetso tse joalo, li tlatselletsa ho litharollo tse tšepahalang le tse nepahetseng tsa ho sesa.
Stabilised Platform vs. Strap-Down INS
Litheknoloji tsa INS li fetohile ho kenyelletsa sethala se tsitsitseng le litsamaiso tsa marapo. Sethala se tsitsitseng sa INS, ho sa tsotellehe ho rarahana ha mechine le ho ba bonolo ho apara, se fana ka ts'ebetso e matla ka ho kopanya data ea analog. HolimaKa lehlakoreng le leng, litsamaiso tsa INS tsa li-strap-down li rua molemo ho tsoa ho sebopeho sa RLGs sa compact le sa tlhokomelo, e leng se etsang hore e be khetho e ratoang bakeng sa lifofane tsa morao-rao ka lebaka la theko e tlaase le ho nepahala ha tsona.
Ho Ntlafatsa ho Tsamaisa Metsu
Li-RLG le tsona li bapala karolo ea bohlokoa litsamaisong tsa tataiso tsa libetsa tse bohlale. Libakeng tseo GPS e sa tšepahaleng, li-RLG li fana ka mokhoa o mong o tšepahalang oa ho tsamaea. Boholo ba bona bo fokolang le ho hanyetsa matla a feteletseng ho etsa hore ba tšoanelehe bakeng sa limisaele le likhetla tsa lithunya, tse bontšitsoeng ke litsamaiso tse kang Tomahawk cruise missile le M982 Excalibur.
