Why is the Fresnel named after Augustin Fresnel?

The Fresnel lens is named after Augustin-Jean Fresnel, a French engineer and physicist who made significant contributions to the study of light and optics in the early 19th century. His work on the wave theory of light led to the development of the Fresnel lens, designed to focus light more efficiently than conventional lenses. This innovation revolutionized lighthouse technology, allowing for brighter and more effective illumination over long distances. Fresnel's advancements in optics have had a lasting impact on various fields, including Photography and telecommunications.
