Abstract :
It is studied Brewster angle refractometry with one instrumental error at availability to measuring´s of materials in the form of samples of different topologies with one or two surfaces of optical quality. The nature of the reflected radiation and its polarization in small neighborhoods of Brewster angle is analyzed experimentally. It is found no infringements of Fresnel theory on Brewster angle, related to behavior of polarization and intensity in reflected light exist. New optical scheme of precise measurement is proposed.
