The Talbot effect, also known as the Talbot phenomenon, is an optical phenomenon that occurs when coherent light (such as from a laser) is illuminated on a periodic structure, such as a grating. When the light passes through the grating, it creates a series of diffraction patterns that repeat at specific distances, known as the Talbot distance.
