Abstract
A first optical fiber coil (A) is disposed adjacent one end of a housing (40). The housing defines an interior reservoir (44) which contains a material (B) having substantial mass, preferably a dense fluid. A second optical fiber coil (C) is mounted to the housing but isolated from pressure or force exerted by the mass material during acceleration. Phase coherent light is transmitted from the laser (10) through the two optical fiber coils. Under acceleration, the pressure or force on the first optical fiber coil causes a corresponding length change. The change in length causes a phase shift of the phase coherent light travelling the first optical fiber coil relative to the light which has travelled the second optical fiber coil. A signal processor (36) translates the phase shift into an indication of acceleration for display on an acceleration indicator (38).
