    The paper describes a new method for evaluating a relative damage accumulated in critical points of all blades of one rotating turbine disc out of sparsely sampled positions of their tips provided by a blade monitoring system. The measured signals are reconstructed with the help of information on approximate resonant frequencies by reconstructing aliased Fourier spectra. The reconstructed signals contain as many resonant frequencies as have been applied for. The relative damage is estimated from the Palmgren-Miner law.
