介绍非相干光产生无衍射Bessel光束的方法及研究现状,对比透过轴棱锥和环缝装置产生白光无衍射光,以及小尺寸全光纤装置产生白光无衍射光束的方法.研究表明：采用相干光源和非相干光源都可以产生Bessel光束,也都具有无衍射和自重建的特性;非相干光源产生Bessel光束具有对光源要求低,单个光源可产生多种波长的无衍射光等优点.
英文摘要：
This paper introduces the methods and the research status of the incoherent light source generating non-dif- fracting beams, compares the methods of generating white Bessel beam by axicon, ring seam and miniature all-fiber de- vice. The research result shows that both the coherent light and incoherent light source can generate Bessel beams and also possess the properties of the non-diffracting and reconstruction. Furthermore, incoherent light source generated Bes- sel beams with lower requirements to the source and a single source can produce non-diffracting beam with various wave- length.
