In this paper the method of Mueller matrix elements measuring by polarization states modulation is considered. This method allows to facilitate research in comparison with the classical method. Using of tanning beams with opposite polarization states makes it possible to measure and compensate systematic errors of experimental setup that arise due to the presence of defects of polarization elements. The use of the results of this paper for investigation of polarization active media is promising.
In the paper we propose a general approach to the calculation of the forming the intensity and polarization fields of the superposition of arbitrary coherent vector beams at points of a given reference plane. The method of measuring photometric parameters of a field, formed in the neighborhood of an arbitrary point of the plane of analysis by minimizing the values of irradiance in the vicinity of a given point (method of zero-amplitude at a given point), which is achieved by superimposing on it the reference wave with the controlled values of intensity, polarization state, phase, and angle of incidence, is proposed.
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
polarization elements.
The polarization structure of a field at the superposition of two plain linearly polarized coherent light waves with the
referent wave with some polarization is considered. It is shown, that with the help of referent wave zero intensity could
be created in any point of a observation plane, if the polarization state of referent wave coincides with a polarization
state in this point without a referent wave, and electrical vector of a referent wave oscillates in counterphase with an
electrical vector of a superposition of the two first waves.
The polarization properties of dielectric films on an absorbing substrate in a neighbourhood of bifurcation points are
investigated. It is shown that polarimetric and ellipsometric measurements of optic-geometric parameters of film
structures are most sensitive in the areas of a bifurcation.
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 Fraunhofer diffraction on the set of identical holes with the same shape and size is investigated. It is shown that the
intensity distribution could be decomposed on two parts. One of them contains information about size and shape of
elementary hole. Second one gives information about mutual position of all holes. The spectrum of second component
allows to evaluate the degree of holes ordering.
The use of a field of polarization waves for revealing and analysis of optical unhomogeneities that are in volume or on a surface of optically homogeneous mediums is justified in this paper. It is shown, that at the presence of phase and amplitude inhomogeneities the scattered wave accepts a variable component of intensity with the certain spectrum of frequencies, which will depend on a concrete type of phase modulation and scatteriung properties of the medium. The use of this method for anisotropic inhomogeneities monitoring in the small-angle scattering is theoretically investigated. The formation of a scattered wave frequency dependence under two types of phase modulation, described by harmonic and triangle-like dependencies, is analyzed.
The angular intensity distribution of light scattered on thin section of eye lens nucleus for the set of 27 bovine lenses with various wet weight is investigated in this paper. It is shown that the intensity distribution is the power function of scattering wave vector. The value of power function exponent increases during the wet weight increase. The random density fluctuation theory is used for scattering elements parameters evaluation.
The amines fluorescence spectra stimulated by UV laser radiation are investigated in this paper. The fluorescence is stimulated by the coherent laser beam with the wavelength 0.337 micrometers . At the sufficient energy of laser stimulation the narrow peaks of the fluorescence spectra are detected besides the wide maximum. The relationship between the fluorescence intensity and the concentration of amines solutions are investigated. The fluorescence intensity temporal dependence on wavelength 0.363 micrometers of the norepinephrine solution preliminarily radiated by UV laser with wavelength 0.337 micrometers was found. The computer stimulated and experimental investigations of adrenaline and norepinephrine mixtures fluorescence spectra were done. The correlation fluorescent method of amines detection is proposed.
