Abstract
The present invention relates to a method and system for condition authentication based upon temporal-spatial analysis of vibrational responsivity. In particular, the present invention provides temporal tracking of reflected secondary speckle patterns generated when illuminating an object with a source of at least partially coherent beam and while applying a stimulated field at different temporal stimulating frequencies.
