Reflection measurement of Hexogen from 5-m distance

The paper presents results of research on a reflection measurement of a Hexogen (RDX) sample from 5 m distance. An experimental setup consisted of a tuning optical parametric oscillator and a hot electron bolometer. The study was carried out with presence of water vapor in the air. The reflectivity of RDX is similar to the reflectivity measured by a time domain spectroscopy setup.
