An optical guide comprises an injection zone intended to inject into the optical guide a light signal and an extraction zone intended to provide the light signal after transport by the optical guide. The optical guide comprises, in a superposed manner, at least two guidance elements. In a zone situated between the injection zone and the extraction zone, the guidance elements are partially separated from one another by a semi-reflective coating of length, in the direction or propagation of the light signal in the optical guide, dependent on a minimum angle of incidence of the light signal and on the thickness of at least one of the guidance elements that the semi-reflective coating separates.
