LOAD DEVICE FOR TESTING MOBILE DIGITAL SPECKLE INTERFEROMETERS OF DEFORMATIVE DISPLACEMENTS

The problem of working out and creation of verification load device for testing mobile digital speckle-interferometers with the current-wave laser, that provides definition of normal deformation displacements is solved. The analytical expression linking difference in phase of interference fields of strained and initial states of object with an offset value of points of its surface. The results of investigation of strains of plates with different requirements of attaching and loading are given.
