Abstract

We have recently implemented a dual-band optical imaging scheme for offshore stand-off oil spill monitoring using visible and long-wave-infrared (LWIR) cameras. Based on differences in intrinsic optical properties, the visible cameral provides daytime images and monitoring capability as if observed by human personnel. The LWIR camera provides both day and night monitoring capabilities based on additional thermal and emissivity contrasts. We have demonstrated the feasibility of such a scheme at various testing sites and under various ambient conditions. We have developed an analytical model to explain observed oil/water contrast. We also discuss limitations in the dual-band scheme using detection boundary analysis and experimental examples. We believe this scheme can provide robust and cost-effective offshore stand-off oil spill monitoring.
