Researchers at Sandia/California are developing innovative optical- and sensing-technology platforms that offer substantial advantages over current methods. Our optical-imaging and laser technologies can be turned into powerful yet portable devices that can be deployed in the field to survey and monitor gases; particulates; and materials, such as explosives, biological agents, and chemicals. In addition, Sandia’s Combustion Research Facility is conducting leading-edge research and development in laser diagnostic techniques. These techniques are used to probe the chemical-reaction mechanisms that occur in combustion processes. We are interested in establishing partnerships to license intellectual property and develop radical solutions for national-security and industrial needs.
A sampling of remote sensing technology projects at Sandia follows:
- Sandia is creating a new generation of compact, efficient laser sources based on optical fibers. These lasers promise to overcome the limitations of previous laser systems and are suitable for field applications. In addition to developing enabling technologies, we are pursuing high-priority applications in national security and energy surety.
- Sandia is developing new IR lasers that employ nonlinear mixing using quasi-phase matched (QPM) nonlinear materials. These materials are microengineered to allow extremely high conversion efficiency and broad tenability. QPM-based lasers enable the development of very compact and efficient in-situ sensors.
- Sandia’s work in this area is proving to be a promising alternative to the existing laborious technique currently used by the Environmental Protection Agency. If the proposed technology can be successfully developed for natural-gas detection, it should be possible to extend this concept to detect other harmful or toxic gases and vapors in the environment.
- Sandia is developing portable imaging instruments that simplify the problem of gas leak detection and location. This technology will accelerate the rate at which gas surveys are accomplished and will significantly reduce costs, minimize the loss of gas to leaks, and enhance safety levels within the gas industry.
- Sandia researchers are developing a portable, laser-based, short-range system that can remotely and noninvasively detect mercury emissions within coal-fired power plant stacks.
