Atmospheric turbulence

Turbulent surveillance-or how to see a Kalashnikov from a safe distance

Combining adaptive optics, real-time adaptation of system parameters, multiplexed imaging, and real-time processing solves the problem of imaging through turbulent atmosphere. Adaptive optics (AO) is the first choice technology for correction of …

Speckle imaging through turbulent atmosphere based on adaptable pupil segmentation

We report on the first results to our knowledge obtained with adaptable multiaperture imaging through turbulence on a horizontal atmospheric path. We show that the resolution can be improved by adaptively matching the size of the subaperture to the …
