Abstract
An optical measuring apparatus for measuring force or pressure, having at least one light source, at least one optical fiber for passing light from and to a sensor, and one detector system. The sensor includes a material having pressure- and force-dependent photo luminescence properties, the signal received in the detector system being dependent on the pressure or the force applied to the sensor.
