Abstract
A hyperspectral imaging system was implemented using active illumination in the 3-4-μm band from an MgO:PPLN ultrafast optical parametric oscillator. Using a staring configuration based on a high-resolution mid-IR camera it was possible to distinguish between liquid chemicals based on their absorption characteristics, demonstrating the potential for standoff detection of a wide range of liquids.
