Abstract
Opto-mechanical analyzer using a single polygon (P) comprising n reflective faces which are arranged parallel to the axis (2) of the cylinder in which the polygon is cut and are determined in such a way that their distribution on the periphery is sinusoidal. The polygon rotates about an axis (1) extending at an angle .theta. to the axis (2) and situated in the plane formed by the axis (2) and the axis (X X') on which the diameter of the cylinder extends. On either side of this diameter the reflective faces have been distributed pairwise parallel. The n faces of the polygon thus have n different inclinations with respect to the axis of rotation and the angular pitch is constant.
