The knowledge of the turbulence strength in the atmosphere is important for many applications. Imagery in the atmosphere experience significant blur when the turbulence is strong. This can be automatically improved (without user intervention) if the turbulence strength is known. The performance of a high-power laser emitting in the atmosphere can be predicted if the statistics of the turbulence strength is known. If not predicted correctly, the laser may unintentionally destroy a target or fail to be able to disable a target.

In this article, we review existing methods that estimate turbulence strength, provide a more in depth error analysis, and propose a new method for estimating and mitigating turbulence in the atmosphere. We focus on methods that are passive in design in order to prevent detection in surveillance scenarios and tactical situations. We also propose a new method, stereo image motion monitor (SIMM) which is a system containing two independent apertures. Our goal in this approach is threefold: 1) We can measure r0 using the DIMM method 2) We can simultaneously estimate r0 individually for each aperture and 3) We have multiple views of the same scene thus can increase the number of frames used in turbulence mitigation methods.
