Atmospheric turbulence degrades focal-plane-array (FPA) camera images because of intensity fluctuation, distortion, and blur, notably for long-range applications. Compressive sensing (CS) imaging techniques use series of measurements whose temporal and spatial characteristics differ from those of conventional FPA systems. The paper discusses how turbulence affects the SWIR image quality using both CS techniques and a conventional InGaAs FPA camera.
