FIELD: measuring equipment, applicable for measurement of rotational speed or turning angle of objects that carry these gyros, for instance, robots, battery-powered trucks, automobiles, ships, aircraft, missiles, etc. SUBSTANCE: fiber optics gyro uses series-connected superluminescent radiator 1, first fiber beam splitter 2, type Lio fiber depolarizer 3, second beam splitter 4 and fiber anisotropic circuit 5. Beam splitter 4 is made of anisotropic fiber. Depolarizer 3 is selected with a ratio of the lengths of the first and second sections as 1:n, where $$$. The second section of depolarizer 3 is formed from the inlet end of beam splitter 4, whose outlet ends are connected to the ends of fiber circuit 5 in such a way that their optical axes coincide. Anisotropic fiber circuit 5 may be done both of anisotropic fiber and of isotropic fiber. EFFECT: enhanced accuracy. 1 dwg |
