Advances in laser, detector, and analysis technologies are enabling the development of powerful tools to address critical measurement needs. Ultraviolet Raman spectroscopic standoff sensors can rapidly detect and identify small quantities of chemical and explosive materials in liquid and solid phases, supporting the mission of first responders. Eye-safe backscatter lidar systems can remotely detect, map, and track aerosols and plumes and simultaneously derive the surrounding 2-dimensional wind fields, yielding information about impending downwind hazards from toxic releases or wildfires. Continuous monitoring for greenhouse gases leaking or emanating from large-area sites provides industry and regulators with high-accuracy real-time actionable data. In this talk, we discuss our work in these areas and the underlying applied physics and technologies.



Dr. Chyba received his Ph.D. from the University of Rochester in Quantum Optics and Laser Physics. His thesis focused on experiments, theory, and simulations to distinguish quantum stochastic from deterministic chaotic behavior in lasers. As a National Research Council postdoc in the Lidar Applications Group at the NASA Langley Research Center, he developed and fielded solid-state laser and laser diode techniques for airborne lidar measurements of water vapor. As Associate Professor of Physics at Hampton University, his Laser Development and Lidar Applications group developed novel solid-state Raman lasers and compact lidar systems to measure tropospheric ozone and aerosols. Subsequently, at ITT, his work focused on the UV Raman detection and identification of hazardous materials, for which he earned the Ring of Quality Award and was named ITT Technical Fellow. He has continued these efforts to develop, test, and field laser-based sensors as Chief Scientist of Spectral Sensor Solutions, a small business headquartered in Albuquerque.
