摘要：
The Fraunhofer diffraction of a Bessel beam focused by an aperture lens is studied both theoretically and experimentally. It has been shown that the Fraunhofer diffraction patterns of Bessel beams are determined essentially by two parameters, namely,the Fresnel number N-a and truncation parameter beta.
