摘要

Bessel beam propagation in scattering media is simulated using the angular spectrum method combined with slice-by-slice propagation model.Generating Bessel beams with a spatial light modulator,which provides a means to adjust flexibly the parameters of the Bessel beam,allows us to validate the simulation results experimentally.The study reveals that the self-reconstructing length changes oppositely with the axicon angle (i.e.,the larger the axicon angle,the shorter the self-reconstructing length).The radius of the incident beam has little influence on the self-reconstruction of the Bessel beam central lobe.
