摘要： According to one aspect, the invention relates to an optical safety component having a plasmonic effect intended to be observed by transmission, including two layers (101, 103) made of a transparent dielectric material, a metal layer (102) that is arranged between said layers made of dielectric material to form two dielectric-metal interfaces (105, 106), and is structured to form on at least a portion thereof corrugations (104) that are capable of coupling surface plasmon modes supported by said dielectric-metal interfaces with an incident light wave. The corrugations are arranged in a first coupling area in a first main direction and in at least one second coupling area separate from said first coupling area, in a second main direction that is substantially perpendicular to said first main direction, said metal layer being continuous on each one of said coupling areas.

摘要： Disclosed is a Rotation sensor with a light source, a light detector, an internal part having a first lateral surface, which is globally cylindrical and convex, and an external part having a second lateral surface which is globally cylindrical and concave. The first and second lateral surfaces both have a same central axis defining a rotation axis for a relative rotation between the internal part and the external part the angle of which this rotation sensor can measure. A first grating is arranged at the first lateral surface with its grating lines parallel to the rotation axis, and a second grating is arranged at the second lateral surface with its grating lines parallel to said rotation axis.
