  1. From the fresnel diffraction equation, we calculated the intensity distribution of the fhb in free space, and found that there is an interested propagation property of the fhb before the focal plane. that is, with the increase of the propagation distance z, the dark spot size ( dss ) of the fhb is first increased, and then decreased, the dss has the maximum value at the position of z = - f / 2
