Abstract

This study aimed to measure high speed deformation with maximum time resolution in the range of a few microseconds. The accuracy of deformation measurement by means of Moire topography of projection type was examined on the basis of geometrical optics. As a rerult of varying the various parameters, the error was reduced by increasing the magnification and the focal length of a projection lens. Exam-ples of real-time and time-resolved Moire topography as applied for the deformation of a thin glass sheet taken by means of a high speed streak camera were presented.
