Generating 3-Dimensional animations of vehicle brake noise

Brake noise investigations using the whole body visual technique of double pulsed holographic interferometry have been extended so that a series of interferograms may be recorded over a cycle of excitation providing information about the amplitude, direction, phase relationship and the mode of vibration of the principal component parts of the brake. This work investigates the possibility of automatically interrogating the holographic images and creating an animated 3 dimensional image of a brake generating noise.
