The random nature of white light speckle is combined with newly developed video digital data acquisition procedures to experimentally determine parameters of interest for a rigid body dynamics problem. Digital correlation of subsequent images during a dynamic event is shown to yield displacements and velocities of discrete points in the rigid body and, therefore, the angular velocity and linear velocity of the rigid body.
