The polarization structure of a field at the superposition of two plain orthogonally linear polarized coherent light waves
with the referent wave with some state of polarization is considered. It is shown, that with the help of referent wave zero
intensity could be created in any point of the observation plane, if the state of polarization of the referent wave coincides
with the state of polarization in this point without the referent wave, and the electrical vector of the referent wave
oscillates in counterphase with the electrical vector of the superposition of two first waves.
The integral relations among optical invariants and elipsometric parameters of light are obtained in this paper. It is shown, that among optical invariants there is an integral relation, similar to Kramers-Kronig relation for complex dielectric conductivity or a complex index of refraction. The possibility to determine the spectral values of conductivity through the integral transform of optical invariants or ellipsometric angles is discussed.
The technique of Mueller matrix elements measuring by polarization states modulation is considered. This techniques
allows to facilitate research in comparison with the classical method. Using of incident beams with orthogonal
polarization states provides measuring and compensates systematic errors of experimental setup causing big defects of
The information is given about the optical arrangement, in which the elements of the coordinate allocations of the Mueller-matrix of the optically thin polycrystalline layers are defined. The algorisms are given and the experimental methods of measuring the Jones-matrix pictures are analyzed. The experimental results of the investigation of the statistical, correlative and fractal parameters are represented and they characterize the Mueller-matrix pictures of polycrystalline systems of the essential types of human’s amino acid.
In this paper, we propose optical tweezers based on a biaxial crystal. To control the movement of opaque particles, we use the shift polarization interferometer. The results of experimental study of laser tweezers are shown. We demonstrates movement of a microparticle of toner using singular-optical trap, rotate a particle due to orbital momentum, conversion of two traps when changing the plane of polarizer transmission and converging of two traps.
In this paper it is shown, that for modulation of path difference it is useful to use symmetrical sawtooth dependence of
path difference in time of order about a wavelength of an optical spectrum. The realization of such temporary
dependence is carried out with the help of piesoceramics and generator of symmetrical sawtooth impulses. The use of
symmetrical impulse essentially simplifies technical realization of phase modulation in a comparison with asymmetric
impulse, which was used earlier.
It is shown, that the greatest value of a resonance amplification is received when the amplitude of phase modification of
path difference is multiple wavelength.
The phenomenon of a laser light scattering on calf eye lenses at the diminution of their temperature is investigated in this
paper. It is shown, that at the cooling of eye lens nucleus cytoplasm the scattered light speckle patterns change from
small-sized speckles two large-sized speckles. Between those two phases the intermediate phase with elongated oriented
speckles is observed. The possibility of using of autocorrelation function and its integration sum for scatterd laser light
speckle pattern investigation is analyzed.
The influence of the coaxially imposed reference wave on the spectrum of space frequencies of a restored image is
It is shown, that the spectrum of space frequencies of a restored field from specklogram without a reference field is
characterized by the greatest breadth. At the magnification of intensity of a reference beam the breadth of a space
frequency spectrum decreases.
It is fruitful to use referent waves in coherent registration and recognition systems. We use the Rau's concept concerning
spatial heterodyning and detecting differences in spatial distribution of light- scattering objects and identification of a
macroform in homodyne process as well. We also use a co-axially imposed reference wave for reconstructing the image
of strongly scattering phase-inhomogeneous object.
The results of experimental investigations of the suggested method of phase-amplitude processing of the recorded speclograms are presented. The effectiveness of the method on the example of reconstruction of distant object's macroform from autocorrelation function.
The paper deals with the technique of processing of speckle- frames of small-sized disseminating objects according to their isophots. Isophots of single contrast built for different intensity levels, result in redistribution of intensity in the maximum diffraction orders, that is in the area remote from low frequency, noise components. It allows adequately to perform the analysis and to define the microshape of an object.
