Turbulence mitigation has long been a challenge in long-distance imaging systems. Holographic aperture ladar (HAL), a multiwavelength spatio-temporal heterodyne 3D imaging modality, is also vulnerable to the deleterious effects of volumetric turbulence along the path of propagation. In this work, we develop a sharpness-maximization turbulence mitigation algorithm using a single phase plane approximation to volumetric turbulence. We show preliminary results that simulated HAL fields aberrated by a single turbulent phase screen, coincident with the pupil, are well corrected using this sharpness-maximization algorithm for turbulence profiles with D/r0 values of up to 50.
