ABSTRACT:
The deflection, due to inertia, of the free end of the cantilever rod of fiber optic material is an indication of the acceleration of the supporting structure of the rod. The indication of the deflection of the rod is by detecting light propagating the free end of the rod. Disclosed are fiber optic rod sensing element structures for acceleration indicators, a rate of change of acceleration indicator, a rotation indicator, and a latching acceleration indicator.
