Abstract
The present invention relates to a fiber-optic measuring apparatus for measuring physical quantities, such as position, speed, acceleration, force, pressure, elongation, temperature, etc., comprising at least one optic fiber for conducting light between an electronic unit and a transducer. The transducer comprises a member having at least one luminescent material, and the position of that member with respect to the fiber end is influenced by the quantity being measured, the output signal from the transducer thus being dependent on the quantity being measured.
