Abstract

We report on the development, construction, and use of a Differential Image Motion Monitor (DIMM) for measuring optical atmospheric turbulence over static and dynamic maritime ranges. The optical properties of the DIMM that make it suitable for such measurements will be presented along with a detailed overview of its software systems. Particular emphasis will be given to the numerical methods, image feature recognition, and learning filters implemented in the DIMM software.
