Method of retro-reflection of a light beam interchanging a vertical and a horizontal coordinates of the light beam's profile and retaining the light beam's linear polarization, which comprises light beam reflection in series from several total internal reflection planes of a transparent material, characterized in that the incident light beam experiences four total internal reflections from three total internal reflection planes (b, e, f, b) of a transparent material during each of which the incident light beam experiences a phase shift between the perpendicular (s) and the parallel (p) polarization components, along with image rotation,where a spatial arrangement of said total internal reflection planes (b, e, f, b) is such that: - during the first reflection the first total internal reflection plane (b) changes propagation direction of the incident light beam from a first beam path to a second beam path, further - the light beam propagating in the second beam path, when reflected from the second and the third total international reflection planes (e) and (f), changes direction of propagation at 180° angle and reverts back onto said second beam path towards the first total internal reflection plane (b), - during the fourth reflection the first total internal reflection plane (b) changes propagation direction of the light beam from the second beam path back to the first beam path, - a plane comprising the first and the second beam paths (4, 5) makes an angle θ with a polarization vector E □ of the light beam incident to the first total internal reflection plane (b), - a plane comprising the second beam path and which is perpendicular to both second and third total internal reflection planes (e, f)" makes an angle φ with said plane comprising the first and the second beam paths (4, 5), wherein the values of the angles θ and φ depend on a refractive index of the transparent material, in which said total internal reflections occur, and are set so that after the fourth total internal reflection a total phase shift between perpendicular (E S3') and parallel (E P3') polarization components of the light beam is equal to π radians, wherein said angles θ and φ are selected to satisfy the condition: θ − φ = + 45 ° + k ⋅ 180 °, whereas k = 0, 1 or 2. - during the first reflection the first total internal reflection plane (b) changes propagation direction of the incident light beam from a first beam path to a second beam path, further - the light beam propagating in the second beam path, when reflected from the second and the third total international reflection planes (e) and (f), changes direction of propagation at 180° angle and reverts back onto said second beam path towards the first total internal reflection plane (b), - during the fourth reflection the first total internal reflection plane (b) changes propagation direction of the light beam from the second beam path back to the first beam path, - a plane comprising the first and the second beam paths (4, 5) makes an angle θ with a polarization vector E □ of the light beam incident to the first total internal reflection plane (b), - a plane comprising the second beam path and which is perpendicular to both second and third total internal reflection planes (e, f)" makes an angle φ with said plane comprising the first and the second beam paths (4, 5), wherein the values of the angles θ and φ depend on a refractive index of the transparent material, in which said total internal reflections occur, and are set so that after the fourth total internal reflection a total phase shift between perpendicular (E S3') and parallel (E P3') polarization components of the light beam is equal to π radians, wherein said angles θ and φ are selected to satisfy the condition: θ − φ = + 45 ° + k ⋅ 180 °, whereas k = 0, 1 or 2.
