The book is a brief historical overview of the development of the lighthouse business. We are talking about the planned replacement of outdated lighthouses in the XIX century with lighthouses with a Fresnel lens.Fresnel's research belongs to the field of physical optics. He made the first optical experiments in 1811. In 1815, he rediscovered the principle of interference, knowing nothing about the work of T. Jung in this area, and added several new experiments to the English physicist, among them the experiment with "Fresnel bizercals". He supplemented the well – known Huygens principle with the idea of coherence of elementary waves and their interference, and based on this in 1818 developed the theory of light diffraction (the Huygens-Fresnel principle). On the basis of this principle, he explained the rectilinear nature of light propagation. He proposed a method for calculating the diffraction pattern based on splitting the wave front into zones (Fresnel zones). Using it, I examined the diffraction from the edge of the obstacle and the round hole. In 1821, he proved the transversity of light waves (independently of T. Jung). In 1823, he discovered elliptical and circular polarization of light, and established the laws of light polarization in its reflection and refraction (Fresnel formulas). Fresnel has the ideas of a fixed ether and partial entrainment of light by moving bodies, which formed the basis of the electrodynamics of moving media by H. Lorentz. Russian Russian lighthouses in the Russian seas have five tables as appendices to the book, and two sheets containing eight engraved illustrations of lighting devices on lighthouses.
