Near-infrared active polarimetric and multispectral laboratory demonstrator for target detection

We report on the design and exploitation of a real-field laboratory demonstrator combining active polarimetric and multispectral functions.

Description
Summary:We report on the design and exploitation of a real-field laboratory demonstrator combining active polarimetric and multispectral functions. Its building blocks, including a multiwavelength pulsed optical parametric oscillator at the emission side and a hyperspectral imager with polarimetric capability at the reception side, are described. The results obtained with this demonstrator are illustrated on some examples and discussed. In particular it is found that good detection performances rely on joint use of intensity and polarimetric images, with these images exhibiting complementary signatures in most cases.
