Abstract:
A method and apparatus for identifying dynamic characteristics of a vibratory object is provided in the present invention, in which a series of dynamic interference images of the vibratory object is acquired through a frequency sweeping procedure and a two-dimensional image scanning procedure. Thereafter, the acquired images are processed for obtaining the corresponding differential fringe density index by signal processing technique of band-pass filtering method so as to further identify the dynamic characteristics of the vibratory object.
