Deformation of multiple asperities model of surface roughness subjected to pressure by flat punch is measured continuously by multiple aperture holographic interferometry and the interaction of asperities is discussed. In this experiment, peak and valley of asperity is observed from just above by selecting the plasticine with small deformation resistance as the model material and by using the transparent flat punch. Asperity models are csne type of single, double and triple with the asperity angle of 150°.
