Abstract:
A method for tracking laser Doppler vibrometer (TLDV) is introduced for operational deflection shape (ODS) vibration measurement of a rotating object to take the advantage of tracking while an encoder is attached to the object. A digital signal processor (DSP) is used to capture the encoder angular position and calculating the signals required for Galvano motors. To verify the performance of the proposed method, comparison with the traditional method is carried out. Finally, the experimental results of ODS vibration measurements of the object without and with rotation are validated and compared to each other to see the effect of rotation on the measured ODS.
