Marie Alfred Cornu (French: [kɔʁny]; 6 March 1841 – 12 April 1902) was a French physicist and professor of École polytechnique. The French generally refer to him as Alfred Cornu. The Cornu spiral, a graphical device for the computation of light intensities in Fresnel's model of near-field diffraction, is named after him. The spiral (or clothoid) is also used in geometric design of roads. The Cornu depolarizer is also named after him.
