Detection of Liquids on Surfaces using Long Wave Infrared Hyperspectral Imaging Spectroradiometer

Not Available "The objective of the Phase I Fast Track STTR is to conduct a feasibility study of detecting liquid contaminants on the ground using a passive LWIR HSI spectroradiometer. SOC has already developed an accurate and validated VIS-LWIR HSI optical signaturecode which includes models of the cold sky irradiance onto contaminated surfaces to determine the differential radiance as a contaminant is placed on various surfaces, e.g., painted metal, concrete, grass and dirt. Due to the importance of the effort, SOChas already identified a qualified Phase II partner to support our effort.The SOC team including Y-12 National Security Complex (NSF designated FFRDC), SSI, TRA and CEB Metasystems has already conducted an initial liquid contaminant detection on various substrates feasbility analysis utilizing a passive LWIR HSIspectroradiometer analytical and hardware sensor simulation models.To satisfy the objective of the Phase I program, the SOC team will conduct the following tasks: (1) Conduct liquid contaminants detection phenomenology definition analysis; (2) Conduct laboratory materials measurements; (3) Conduct liquidsimulant/background signatures simulations; (4) Define LWIR HSI spectroradiometer requirements; (5) Conduct LWIR HSI spectroradiometer laboratory and field measurements; (6) Identify potential sources of capital for commercialization; (7) Providereporting. Completion of these tasks will satisfy the objective of our program, "to conduct a feasibility study of detecting liquid contaminants on the ground using a passive LWIR HSI spectroradiometer."The effort will develop the technical underpinnings for a real-time LWIR HSI sensor and signature based processing techniques to detect liquid contaminants on various battlefield surfaces. Using laboratory materials measurements and the available ENSIRsimulation code, SOC will determine the expected performance of a LWIR HSI spectroradiometer to detect the liquid contaminants so as to be able to define a realistic Phase II plan for development and demonstration on an improved breadboard LWI
