The algorithm of dense spectrum correction has been raised and proved based on the correction of discrete spectrum by fast Fourier transform. The result of simulation shows that such algorithm has advantages of high accuracy and small amount of calculation. The algorithm has been successfully applied to the analysis of vibration signals from internal combustion engine. To calculate discrete spectrum, fast Fourier transform has been used to calculate the discrete spectrum by the signals acquired by the sensors on the oil pan, and the signal has been extracted from the mixed signals.
