A practical method of measuring small transverse vibrations of diffusely reflecting objects, the basic principle of which is the use of the oscillatory motion of a system of Interference fringes modulating the spectrum-structure of the scattered field, is described. The main element of the system is a diffraction grating with specularly reflecting rulings and transparent gaps between them, which serve simultaneously to illuminate the specimen and to spatially filter the scattered radiation.
