WebMar 15, 2024 · The Fresnel integral named after Augustin-Jean Fresnel (1788–1827) was first studied by Euler in 1781. Fresnel used this function in 1818 to study the illumination intensity of optical diffraction patterns [ 1 ]. The Fresnel integral is an odd function and has mirror symmetry [ 2, 3 ]. WebJul 8, 2024 · Instead, Numerical techniques are used to evaluate the following definite integrals: S(x) = ∫ x 0 sin(t2) dt, and C(x) = ∫ x 0 cos(t2) dt Which are known as the Fresnel integrals. Typically the values of these function are calculated using computer algorithms, or looked up in tables (in a similar way to that of the Normal Distribution ).
