Abstract

The presence of distributed-volume or "deep" turbulence presents unique challenges for beam-control applications which look to sense and correct for disturbances found along the laser-propagation path. This study uses five spatially distributed phase-only reflective spatial light modulators (SLMs) to accurately model deep-turbulence effects. In practice, we can match the Fresnel numbers for tactical engagement scenarios using optical trombones and relays placed in between the SLMs. Similar to computational wave-optic simulations, we can also command repeatable high-spatial-resolution phase screens to the SLMs with the proper statistics (i.e., Kolmogorov, von Karman, etc.).
