OptoAtmospherics, a spin-off of Michigan Aerospace Corporation (MAC), is exhibiting at WINDPOWER 2009 (booth #4381), the largest annual wind power conference in the world. The conference and exhibition runs from May 4 through May 7 in Chicago. OptoAtmospherics, formerly known as WindSight, is dedicated to applying MAC’s extensive Light Detection and Ranging (Lidar) atmospheric sensing technology to the wind energy industry. By providing highly accurate wind speed, direction, temperature, and density measurements over large volumes, OptoAtmospherics will be offering a product line that has value for site assessors, wind farm owner/operators, and turbine manufacturers.
