Paper Abstract

This paper focuses on the development of very compact remote sensing systems. Accurate wind sensing plays an important role in aviation. Near term applications include: air data sensors, wind shear detection, and performance measurement. Future applications extend to space, utilizing satellites for sensing global and regional winds. These applications require practical solutions that are ultra-reliable, utilize minimal space, cooling, and power and are easily integrated into the parent system. This paper describes design approaches that can be adapted for use with rapidly advancing coherent and eyesafe semiconductor laser technology. These coherent sources have demonstrated over one watt and are commercially available. Results of hardware development using cw solid state lasers for coherent detection while utilizing internal fiber reflections as the local oscillator signal are presented. Finally, future activities are outlined.
