Science and technology play an ever-increasing role in the mission of the U.S. Department of Homeland Security (DHS) and the military.
Intelligence and surveillance are necessary to detect and disrupt a terrorist act in the planning stages. Advanced technology, including radars, sensors, cameras and software are required for this mission. Ongoing research is providing ways of protecting our cities, borderlands, airports, and other ports of entry with the least impact on our day-to-day lives.
Remote Sensing Group (RSG)
The Remote Sensing Group (RSG) in the College of Optical Sciences is best known for its work on the in-flight, radiometric calibration of remote sensing imagers using ground-based measurements at desert test sites. Radiometric calibration in this context refers to the ability to take the data from a sensor and convert it to a standard energy scale. Such work allows for the comparison of data from an array of imagers (by last count more than 30 sensors). The methods of the group have been in use since the mid-1980s and currently provide absolute radiometric calibration to better than 3 percent, both in accuracy and precision in the mid-visible.
RSG’s work has led to participation in round-robin laboratory calibrations with national laboratories and sensor manufacturers. The work also includes strong interactions with NASA and space agencies from other countries.
