Paper Abstract

For the optical sensing in random media, an annular beam was used because of its nondiffractive feature. In our previous work, we have confirmed the nondiffractive effect of the annular beam in diluted solution of milk as random media. In the experiment of this study, increment of the nondiffractive effect has been confirmed by using the pulsed annular beam. We have simulated propagation characteristics of the annular beam in random media by wave analysis method. The attenuation rate and the forward scattering pattern of the propagation beam were calculated, and it showed agreement by comparing them with results of the experiment.
