Fibre optical gyro.

摘要

In an ammunition unit use is made of a fibre-optic gyro with one or more fibre-optic loops (2, 3, 4). Each gyro quantity in the form of roll, pitch or yaw angle can be measured by detecting the phase displacements of the light in each loop. The loop or at least one of the loops extends essentially connected on or in the ammunition unit shell (1). A centre axis (2a, 3a, 4a) extending at right angles to the plane of the loop is inclined relative to the longitudinal axis (1a) of the ammunition unit.
