We show that the dielectric grating induced by an external probe in a photorefractive crystal
with the period of the external probe can be unstable against period multiplication. We …

The speckle correlation technique is a powerful tool for measurements of the rough surface
displacements and vibrations. 1 Its main advantage is a simplicity of the optical setup, which …

We describe an adaptive interferometer for linear detection of small out-of-plane vibrations
of optically rough surfaces. The interferometer is based on the polarization self-modulation …
