摘要: Light transmission of Laguerre Gaussian (LG) vortex beams with different orbital angular momentum (OAM) values (L) in scattering beads and mouse brain tissue media were experimentally investigated for the first time comparison (G) beams. The LG OAM were generated using a spatial light modulator (SLM) reflection mode. consist of various sizes concentrations latex water solutions. transmissions G beams through measured ratios sample thicknesses (z) to mean free path (l s ) turbid media, z/l . results indicate that within the ballistic region where is small, G show no significant difference, while the diffusive higher, higher than In region, L with lower due eigen channels media. transition points from to diffusive regions for studied.
