Fiber optical sensors based on fiber Bragg gratings are increasingly used in applications that are not accessible to conventional electrical sensors. However, measurement applications, which are based on the detection of dynamic quantities, are not yet state of the art. This thesis examines the technical hurdles related to the acquisition of dynamic measurands. An algorithm developed in the context
of the work allows the detection of aliasing effects from spectrometrically detected fiber Bragg grating signals. The implementation of an optical low pass filter for the band-limited detection of dynamic fiber Bragg grating signals is discussed. A comprehensive description of intensity-based measurement systems regarding measurement errors and uncertainties is given. The development of a highly integrated intensity-based measurement system for use aboard the ARIANE launch vehicle is presented.
