PSI’s Multi-Aperture Differential Image Motion Monitor

Press Release

Physical Sciences Inc. (PSI) has been awarded a research program from the Naval Underwater Warfare Center to develop a compact multi-aperture differential image motion monitor (MA-DIMM) to measure three-dimensional marine atmospheric turbulence.

PSI’s MA-DIMM will be integrated with a 3-band picosecond laser and provide 3D range-resolved profiles of the atmospheric structure constant to quantify marine boundary layer turbulence. The MA-DIMM technique is based on a diffractive beam splitting optic and range-gated focal plane array (FPA). A four-aperture MA-DIMM is projected to achieve 20 discrete range measurements within the threshold operational range of 5 km.

Development of this MA-DIMM will increase situational awareness, performance, and safety for high-energy laser (HEL) applications in maritime environments. The MA-DIMM would also benefit free space optical communications and meteorological sciences, providing 3D mapping of marine turbulence that may be used to plan for ideal laser trajectories over a larger field-of-regard than current technologies.
