Abstract

The invention relates to a fibre-optic accelerometer for determining acceleration along an axis, comprising an optical fibre with a fibre end face and an acoustic membrane with a membrane frame, a deflection mass and connection bridges, the acoustic membrane being designed to reflect, at least in part, a primary radiation from the fibre end face, and the connection bridges connecting the membrane frame and the deflection mass at least at two different axial positions.
