Claim 8:
9. A od for detecting internal defects in railway tracks, comprising:
applying, by an excitation mechanism of a mobile defect detection platform to a railway track as the mobile defect detection platform travels along the railway track, multiple impact forces;
capturing, by at least two laser Doppler vibrometers of the mobile defect detection platform while the mobile detect detection platform travels along the railway track, vibration data representing vibrations of the railway track caused by application of the multiple impact forces by the excitation mechanism; and
detecting, based at least in part on the vibration data captured by the at least two laser Doppler vibrometers, an internal defect in the railway track.
