In mathematics, the Pearcey integral is defined as [1]
The Pearcey integral is a class of canonical diffraction integrals, often used in wave propagation and optical diffraction problems [2] The first numerical evaluation of this integral was performed by Trevor Pearcey using the quadrature formula. [3] [4]
In optics, the Pearcey integral can be used to model diffraction effects at a cusp caustic, which corresponds to the boundary between two regions of geometric optics: on one side, each point is contained in three light rays; on the other side, each point is contained in one light ray.
