Hybrid Talbot effect.

The Talbot effect resulting from a hybrid superposition of Hermite-Gaussian beams and Laguerre-Gaussian beams is studied theoretically. The traditional Talbot effect associated with periodic gratings can be explained by the superposition of a series of plane waves. More recently, it has been found that other beams (such as Airy beams and Bessel beams) can be used to construct the Talbot effect as well. In this paper, we further propose that a hybrid field composed of different types of beams can also exhibit the Talbot effect, called the hybrid Talbot effect. We believe that the founding of this effect will provide a deeper insight into the subject of self-imaging and have potential applications in optical imaging and optical coding.
