ABSTRACT:
The invention relates to an optoelectromechanical apparatus for measuring physical parameters, as pressure or force, comprising an emitting optical fibre coupled via its input with a light source, receiving optical fibre connected over its output to signal processing means and a carrier including a resilient member for bearing the emitting and the receiving optical fibres, wherein the input of the receiving optical fibre is in optical coupling with the output of the emitting optical fibre, advantageously through a spacing and the processing means comprise a first and a second photodiodes for detecting light of the light source and the light output of the receiving optical fibre.
