A Novel Rotation Sensor Based on Measurement of the Brewster Angle in a Moving Medium.
Abstract
Linearly polarized light incident on a stationary medium at an angle whose tangent equals the relative refractive index is not reflected, provided the polarization is in the plane of incidence. Analysis of this situation for a moving medium leads to the prediction of a novel relativistic effect. The effect suggests a generalized experiment of the Fizeau type to determine the velocity of propagation in a moving refractive medium where the direction of propagation is not parallel to the motion of the medium. Such an experiment would examine the Einstein velocity addition theorem. The possible use of the effect as the basis of a novel optical rotation sensor differing from the gyro-laser in its principles of operation is discussed. Both the significance of the Fresnel drag law in relation to the Fizeau experiment and Potier's principle, which sets forth a universal consequence of the Fresnel law, are summarized. A translation of Potier's paper, which is not readily available, is included. (Author)
