Title: Optical fiber gyro of optical heterodyne system
Inventor: NAKAI HISANORI
IPC: G01C19/72
Filed: 1983-05-25
Abstract: PURPOSE:To measure at high accuracy a rotating angular velocity, by using single-mode optical fiber wound up in a ring, half-mirrors in 3 outstanding positions and introducing a polarized light subsequent to a frequency shifting to the last half-mirror by means of a surface reflecting light. CONSTITUTION:A linear polarized light from a light source 1 is divided into two by a half-mirror 11a, the reflected light is converted to a CW wave light after propagating around a single-mode optical fiber 7 and the transmitted light to a CCW wave light after passing through a half-mirror 11b also. Further, the CW wave light is reflected by half by the mirror 11b and it is reflected by a mirror 12 after passing through a frequency shifter 8. This polarized light is reflected again by a half-mirror 11c and after composition with the CCW wave light and introduction into a receiver 9, it is detected. When the fiber 7 being wound-up is rotated, difference of CW wave light and CCW wave light on their light paths creates a displacement of interference fringes and a signal of composed beat frequency is obtained in the receiver 9. By this way, the rotating angular velocity can be measured at high accuracy.
