The superposition of two plane waves with different frequencies and different polarizations is considered. It is shown that electrical vector moves along complex trajectory, which is similar to the Lissajous figures. The characteristics of possible trajectories are analyzed. The results of computer simulation are presented.
The possibility of formation of the beam with edge dislocation, which is similar to the ТЕ01(10) beam is considered. It is shown that such mode may be obtained due to the diffraction of plane wave on the complex Bragg hologram, constructed as composition of two grating recorded on the same place of registration media. These partial holograms are implemented as the gratings with constant period and close characteristics. The conditions of such operation are formulated. The experimental results are presented.
The possibility of formation of the beam with edge dislocation, which is similar to the ТЕ01(10) beam is considered. It is
shown that such mode may be obtained due to the diffraction of Gaussian beam on the special binary computer generated
hologram. The conditions of such operation are formulated. The experimental results and results of computer simulation
are presented.
In the paper, we take it into one's head to show how different parameters of an optical wave are connected and what follows from this connection. The results of computer simulation are presented.
The connection between contrast changes of intensity distribution of speckle pattern, obtained for polychromatic
illumination of scattering object and coherence characteristics of wave is considered. It is shown, that changes of mean
contrast of speckle field (from center of pattern toward the periphery), obtained for quasimonochromatic illuminating
wave may by connected with spectral range of the wave. The experimental results are presented.
