Family of Non-Diffractting Beam
摘要
Abstract
Non-diffraction solutions of wave equation can be obtained in Cartesian coordinates,cylindrical coordinates, elliptical cylindrical coordinates and parabolic coordinates,those are Cos (Cosine)beam,Bessel beam,Mathieu beam and Parabolic beam,and they make up the non-diffracting family (also known as Helmholtz beam).In this article,we intro-duce their specific expression,beam intensity distribution and self-reconstruction process.At last the four non-diffracting beam were compared to each other,and we sum up the hot applications of the diffraction-free beam and look to the future.关键词
