Abstract

From the irregular fringe patterns produced by the Fourier transform of a multiply exposed specklegram we may extract information about the kinematic parameters of a linear motion. The initial velocity, acceleration, and age (i.e., the time interval of the motion) for a uniform accelerated motion are computed from the results of a spatial frequency analysis.
