Abstract

We propose here a method of detection of small displacements, in which the speckled image of the object is modulated by an additional speckle. Due to this additional speckle, the Fourier transform fringes of the doubly-exposed photographic plate undergo a diminution of contrast when the object suffers a displacement.
