Experimental results have been given on laser-damage resistance of the liquid crystal modulator with longitudinal operating electrical field. It was shown that laser-damage resistance of the modulator is limited by the ITO transparent electrodes and

A contradiction between high efficiency of an amplifier operating in a saturated mode, and nonlinear distortions in image reproduction characteristic for this regime is solved. A lasing medium is located in a Fourier-plane of the image, its gain prof

The applicability of the transform algorithms generally used in projection computed tomography is substantiated for the case of medical diffuse optical tomography (DOT). To reconstruct tissue optical inhomogeneities, a new method based on a concept o

The possibility of application of the photon average trajectories (PAT) method to real-time reconstruction of tissue inhomogeneities in diffuse optical tomography of strongly scattering media has been substantiated. By this method, the inverse proble

The applicability of backprojection algorithms of filtered shadows that have been earlier developed for computer tomography is shown for the case of optical tomography of strongly scattering media. This opportunity is based on the presence of a long

Theoretical analysis and numerical experiments show a significant difference in a temporal dynamics of shadows caused by absorbing and scattering macroinhomogeneities. This difference is especially noticeable at the leading front of the pulse passed
