Partially transparent and partially retroreflective optical component with plane-symmetrical deviation

An optical component, extending in a main plane, and having an entry face and an exit face opposite, planar and parallel to the main plane, comprising:

• a first transparent layer, having the entry face, and a second face opposite, planar and parallel to the main plane, and comprising retroreflective micro-recesses, in the form of a truncated pyramid, extending from the second face;
• a second transparent layer, having the exit face, and extending on and in contact with the second face of the first layer and the micro-recesses;
• wherein:
• the micro-recesses are arranged as separate retroreflective strips parallel to one another, such that the retroreflective strips are separated two by two by a transparent longitudinal portion not comprising micro-recesses,
• and such that the micro-recesses of one and the same retroreflective strip are up against each other and oriented along a transverse axis of the retroreflective strip.
