Paper Abstract

In step-like deformations, discontinuous deformations, the techniques using a laser beam of single wavelength cannot measure the deformation amount. Because the deformation changes between captured specklegrams would be larger than the wavelength of the laser. We have developed the technique that can measure the large deformations having step-like discontinuities by using two laser beams of different wavelengths.
