This paper presents the results of investigations of light scattering and transmission in porous glass-liquid crystal (LC) and polymer systems. It was shown that for cholesteric LC in macropores (unlike the nonmesogenic system isotropic liquid-porous matrix) polarized component of scattered light intensity cannot be described by the sum of intensities caused by: doublescattering, scattering by the matrix, scattering due to the refractive index mismatch between LC and the glass, scattering by the density and the order parameter fluctuations. The existence of essential surplus light scattering, its dependence on the wave number and results of temperature measurements are explained with the only assumption that LC in pores at temperatures above the critical one is pseudotwo phase system with anisotropic interphase layer on pore walls arrising as result of orientational wetting. The interpretation of the results of optical investigations of comblike polyalkylmethacrylates in macroporous glasses is based on the suggestion of the existence of orientational order in the arrangement of relatively long side radicals, which is induced by the pore surface.
