Porous materials are very unique materials that have many characteristics such as light weight, filtering, shock absorbing properties, etc. Especially, a porous material is thought to be a multi-functional material which has shock absorbing and damping properties. In this study, the local deformation during a short-time deformation of a porous metal was observed by the moiré method using a digital high-speed camera. A 50µm square grid made of stainless steel or a polymer was placed on the surface of the porous metal and polymer for the model grid and an image sensor from a digital high-speed camera was used for the master grid of the moiré method. The impact test (dropping weight test) was used to measure the deformation of the porous materials during a very short time and was obtained from the moiré fringe produced by this method. The strain caused in a very short time was also measured by this method.
