Abstract
LIDAR (LIght Detection And Ranging) systems have proven their value in the remote measurement of spatially resolved atmospheric wind velocities in a number of applications, including the detection of clear-air turbulence, wind shear, aircraft wake vortices, and microbursts. The capacity of coherent LIDAR systems to produce a continuous, real-time 3D scan of wind velocities via detection of the Mie backscatter of atmospheric aerosols in clear-air conditions and at stand-off distances of up to 50 km at relatively low pulse energy gives this technology a clear advantage over other atmospheric monitoring technologies.During the execution of contract NNX11CG87P SIBELLOPTICS assembled the key components of the fiber-based transceiver in a breadboard system and demonstrated performance against proprietary LIDAR modeling. In addition, we were able to demonstrate 12 hour battery-powered operation, a unique, compact BPLO method that uses quad-cells, and were able to take a significant step towards future miniaturization by packaging the fiber sub-assembly on a 1-ft x 1-ft optical bench.In Phase II, it is proposed that, based upon Phase I efforts, a brassboard version of the fiber-LIDAR system be designed, assembled, and tested including data collection, processing, and display capabilities. The system will include custom opto-mechanical designs of mounts and benches, packaged components for reduced SWAP and more robust operation, and higher output energy to increase sensitivity. Software will be developed to demonstrate real-time capability to collect, process, and display data in real-time using a unique interactive user interface.
