摘要：
In this paper, we discuss the real-time compensation of air turbulence in imaging through long atmospheric paths. We propose the use of a reconfigurable hardware platform, specifically field-programmable gate arrays (FPGAs), to reduce costs and development time, as well as increase flexibility and reusability. We present the results of our acceleration efforts to date (40 x speedup) and our strategy to achieve a real-time, atmospheric compensation solver for high-definition video signals.
