• Extends RMLD™ platform to liquid hydrocarbon leak detection
– Adopts recent advances in room-temperature diode laser technology operating near 3 microns
• Addresses a industry need for detection of petroleum product leaks from buried pipelines too small for detection by SCADA-type inventory control systems
– Secures valuable petroleum product
– Protects the environment
– Decreases the time/cost of searching for and repairing buried pipe leaks
• Project culminates with demonstration of prototype man-portable sensor to detect underground gasoline leaks
