ABSTRACT:
In a stabilized fiber optical measuring device for measuring dynamic transients of physical magnitudes, a transducer acted upon by the physical magnitude to be measured receives light transmitted by an optical fiber from a light generator and transmits an optical signal to an optical detector. The transducer modulates at least part of the optical input signal such that the optical output signal therefrom contains at least one measuring component representing the magnitude to be measured and at least one stabilization component. The optical output signal is detected and the measuring component and the stabilization component are separated from one another and respective electrical signals generated such that the dependence of the measuring signal on instabilities in the measuring device can be compensated by a compensating signal. The transducer also attenuates the optical input signal in dependence on the magnitude of the measuring component.
