Fermi pencil beams and off-axis laser detection

This paper concerns the analytic reconstruction of properties for narrow laser beams propagating in turbulent atmospheres. We consider setting off-axis measurements based on wide-angle single scattering light detected away from main path beam. Light propagation beam itself is modeled by macroscopic approximations radiative transfer equations that take form Fermi pencil or fractional equations. allows a simplified procedure beam’s constitutive parameters, particular, its direction and location emitting source.
