Two schemes of the image acquisition through a multimode fiber are suggested. Both are based on the assumption that the input-to-output propagation Green function is stabilized by some or other technique. In both schemes the object is characterized b

A scheme for correlation dimension measurements is suggested. It is based on the holographic grating recording in a photorefractive crystal and can operate in a real-time scale without restrictions on the values of the dimension measured.

The authors explored tensor properties of chi (2) gratings induced in bulk glass under different polarization conditions. Three cases were studied: recording of gratings by waves with parallel, orthogonal and 45 degrees -tilted polarizations. The res

The propagation of light in a multimode optical fiber waveguide results in speckle, a complicated mapping of the input field onto the output field. The speckle pattern changes as the fiber undergoes twists and bends. We show theoretically and demonst

A new method for the measurement of the phase shift between second-harmonic light generated by a bulk glass and the injected second-harmonic seed is presented. A linearly polarized pump and a second-harmonic seed with noncollinear polarizations were

Beams at the output of an axially symmetric multimode fiber were produced with mostly positive or negative values of angular index m through skew illumination of the input end of the fiber. In this way rays with predominantly positive or negative hel

The report is devoted to the experimental realization of the BRIEFING-type image reconstruction procedure. We used a 23 /spl mu/m-thick nematic liquid crystal cell as a nonlinear element, which introduced phase modulation proportional to the local in

Propagation of a monochromatic light through a multimode fiber is considered in connection with the problem of image transmission. We discuss the variations of throughput scrambling, i.e., of the pixel-to-pixel Greens' function for transmission under
