| Research Abstract |
A new moire method using high speed digital camera has been developed. A digital high-speed camera with a solid state image sensor readout unit was used to observe the moire fringes of the specimen during an impact test. The very fine metallic mesh was used for the model grid and the pixel array of the solid state image sensor readout unit was used for the master grid. Comparing to the other high-speed moire method using a master grid, it is possible that a number of pixels for a moire image can be decrease and the interval of each image shorten.
