Abstract

In the present work, we propose an experimental setup to investigate the effect of atmospheric turbulence on user-defined beams. The user-defined beams were formed by writing reconfigurable patterns on a spatial light modulator, allowing the impact of atmospheric turbulence to be investigated simultaneously and in real time. The programmable controllability provides several flexibilities to the system, such as the ability to create different beam types simultaneously, control the separation between different beams, compensate for aberrations, and easily switch between different beam types. The experimental results illustrate the feasibility and effectiveness of the proposed experimental setup for studying the impact of atmospheric turbulence on different beams simultaneously in laboratory settings using a pseudo-random phase plate.
