摘要：
We obtained a twisted far field with rectangular hollow distribution by designing a new type of light source, which can rotates around the axis during propagation. Then, we derived the expression of cross spectral density function on propagation of such source and analyzed the characteristics of spectral intensity distribution of beam field. In addition, we discussed the influence of corresponding parameters of such a source on the behavior of the beam field, including thickness of the hollow edge, the size of the hollow, and direction of beam rotation in detail.
