FIELD: physics, optics.
SUBSTANCE: invention relates to versions of optical reflector systems for laser location and range-finding. The solution is based on that the structure of a reflector includes an optical wedge made of birefringent monoaxial optical material and a quarter-wave retarder. Said wedge is placed at the input of the reflector such that the optical axis of its material is in a plane perpendicular to the optical axis of the reflector. Light is deviated by the optical wedge after passing through the quarter-wave retarder twice. The deviation value depends on the value of the apex angle of the wedge and its refraction index.
EFFECT: improved energy characteristics of light flux reflected from a retroreflector and directed towards a source and a receiver owing to compensation for the deviation of light flux caused by velocity aberration.
