説明
For optical sensing, an annular beam is widely used because of its ability to self-transform into a nondiffractive beam when it propagates in air. This ability, however, is difficult when it propagates in random media because of scattering. To analyze the characteristics of annular beam propagation in random media, we proposed a new wavefront analysis method based on geometric optics approximation. In this algorithm, we adopted a simplified geometric optics approximation and iterative calculation based on forward scattering and simulated the attenuation and the scattering waveform of the annular beam in random media. By this simulation, we got a non-diffractive beam waveform at the optical axis with a certain propagation distance and media concentrations. The numerical analysis results were compared with the experimental results.
