The white light speckle method is used to study the in-plane and out-of-plane vibration of plates. By suitable choice of experimental set-up, the amplitude of vibration and location of the nodal or antinodal regions can be determined. For in-plane vibration studies, the object is coated with a layer of retro-reflective paint, which creates a random speckle pattern when illuminated by a beam of white light. Filtered time-averaged patterns recorded in this way gives the amplitudes of the sinusoidal oscillation. For out-of-plane vibration studies, the reflection speckle method and the projection speckle method provide the anti-nodal and nodal regions respectively.
