摘要：

It is shown that the breaking of azimuthal symmetry during the oblique entry of relativistic particles into a thin target leads to oscillations of the spectral-angular density of polarized Cherenkov radiation along the azimuthal angle. The effect of modulation of the angular distribution of Cherenkov radiation can be observed in quartz glass on individual spectral lines in the optical and near ultraviolet ranges. The interference maxima have a small angular width not exceeding 10(-2) rad. The effect can be used in the diagnostics of the angular characteristics of beams of accelerated relativistic particles.
