An evaluation program was undertaken on a remote oil film detection instrument which uses the infrared reflectance of water surfaces. Oil slick detection is based on a change in the normal water reflectance ratio of two wavelengths in the 3 micron spectral region. Laboratory and field tests demonstrated the instrument's ability to reliably detect petroleum films while effectively ignoring non-hydrocarbon pollutants on the water surface. The report details test procedures and results as well as theory of operation and functional descriptions of the instrument.
