<p>The invention pertains to optical location systems and takes the form of an optical reflector with objectives (2) distributed over a spherical body (1) and with reflecting elements situated at the foci of and optically coupled to each objective in the form of planar mirror facets ('a') of a polyhedron (3) inside the body (1) and inscribed inside a sphere which is concentric with the body (1). Each facet ('a') is perpendicular to the optical axis of the corresponding objective (2); the polyhedron (3) can be such that its apexes touch the inner surface of the body (1), and each coupled objective-reflecting element pair can have an optical filter (4) secured to the spherical casing (5) which is concentric with and encloses the body (1) and can rotate about the latter. The optical filters (4) of different objective-reflecting element pairs and the reflecting elements are spectrally different and the polyhedron (3) can rotate about the body (1).</p> |
