Title: Total single-polarization fiber rotary sensor
Inventor: OKAMOTO KATSUNARI
IPC: G01C19/00
Filed: 1984-04-14
Abstract: PURPOSE:To reduce noises originating from disturbance due to mechanical oscillation, etc., by using a fiber type polarizer which uses a birefringent fiber instead of a bulk polarizer and using birefringent fibers for the whole part except a light source and a photodetector. CONSTITUTION:Light from a laser 11 is passed through a half-wavelength plate 13 and polarized wave parallel to the main axis of a 3dB optical coupler 15 is obtained from a birefringent fiber. When linear polarized light which is polarized in the main-axis direction of the fiber 23 is incident, linear polarized light whose incidence power is reduced to half appears at projection-side 23a and 24a. There is no problem when the loss that an (x) polarized wave in propagation mode has is <=1dB/m, and the cutoff wavelength lambdac of the fiber is so designed that lambda/1.7<= lambdac<=1.4, where lambda is the wavelength of the light source. Both (x) and (y) polarized waves in use have such wavelength that they propagates in a fiber coil 18. When the sensor is so designed that the (y) polarized wave does not propagate substantially, the influence of mode coupling in the coil is eliminated and a stable rotary sensor is realized.
