Abstract
An experimental study was undertaken to measure the absolute reflectance of a large number of landmines using a single- mode laser diode operating at approximately 814 nm. Approximately thirty different anti-tank (AT) and anti- personnel (AP) mines were irradiated with a highly polarized laser beam configured in a monostatic geometric arrangement. The in-plane (p) and out-of-plane (s) linear polarization components were measured as a function of incidence angle of the transmitted laser energy. The relative value of the reflected power of each polarization component was calibrated against various reflecting Spectralon panels to obtain an absolute reflectance. This effort is being undertaken in support of an Army Program using an active laser system.
