Title:
OPTICAL FIBER GYROSCOPE
Document Type and Number:
Japanese Patent JPH02212712
Kind Code:
A
Abstract:
PURPOSE:To obtain a device with excellent environment resisting performance by using a vertically symmetrical fiber bobbin pertaining to a mounting section with a gyrobase so that two points of an optical fiber are positioned in a vertical symmetry on the same layer at an equal distance from a midpoint. CONSTITUTION:A fiber bobbin 1 is formed in a vertical symmetry pertaining to a mounting section 2 with a gyrobase. Therefore, an optical fiber can be wound to ensure that two points thereof are positioned in a vertical symmetry on the same radius at an equal distance from the midpoint 3c thereof or that they are in the same direction in a fiber loop as a whole. With such an arrangement, for example, heat flowing in from outside a gyroscope is transmitted in a vertical symmetry to the fiber loop through a heat bridge 2. Thus, a rate of change in temperature at two points at an equal distance from the midpoint 3c of the optical fiber always gives an equal value, thereby reducing a phase difference to zero by canceling.
