Active Sensing and Imaging
Team goal
In the Center for Active Sensing and Imaging (CASI) at Utah State University, the main goal is to use radar-like, laser-based LIDAR technology to measure distances instead of radio waves, for a variet of industrial applications, including sitting wind farms, controlling emissions, and rapid replacement of bridges, runways and other infrastructure.

Team description
USTAR is helping Utah take the international lead in using advanced laser technology that has the potential to revolutionize a myriad of industries. Building on the strength of the work of Robert Pack, Paul Israelsen, Gail Bingham, and Tom Wilkerson, the Center for Active Sensing and Imaging (CASI) at Utah State University has become a world leader in directed energy sensor technology.
This technology "shoots" energy, usually light in the form of laser pulses, at a target. The distance data collected when the light bounces back to the instrument are highly precise. One of CASI's areas of focus is LIDAR (light detection and ranging) technology. CASI is employing LIDAR to study wind patterns and geography to find optimal locations for wind farms. It's also using this technology to provide increased detail and accuracy for weather modeling and forecasting.
CASI is developing portable instruments that use LIDAR to detect pollution from agricultural sources, such as feedlots. These devices are able to track and quantify gaseous emissions and help those who run agricultural operations meet emissions regulations.
Using LIDAR technology to gather detailed terrain information, UDOT was able to replace the 4500 South bridge on I-215 in one weekend rather than the months it normally takes, thereby saving Utah residents from major traffic congestion.
CASI is working to apply directed energy sensing technology to solve several national defense challenges. For example, this technology is being used to help detect explosive mines underwater to protect military ships and submarines.
In February 2009, a local TV station profiled the research taking place at CASI's labs. KSL-TV profiled how the team is developing technology to "map the wind" and help alternative energy wind farms become more efficient. Watch the clip here.
USTAR recruited Dr. Allen Howard to Utah State University. He now heads the Laboratory for Atmospheric Remote Sensing within the Center for Active Sensing and Imaging at Utah State University. Prior to joining USU, Dr. Howard's work resulted in two U.S. patents, many technical publications and the formation of Terragraf, a high-resolution subsurface imaging company. Dr. Howard is also a member of the technical staff at the Dugway Proving Ground.
Another key USTAR recruit is Dr. Alan Marchant, who is working on, among other aspects, satellite applications of the technology.
