Abstract

A compact laboratory demonstrator providing both active polarimetric and multispectral images is designed. Its buildings blocks include, at emission part, a multi-wavelength optical parametric oscillator and, at the reception part, a polarimetric hyperspectral imager. Some of the results obtained with this system are illustrated and discussed. In particular, we show that a multispectral polarimetric image brings additional information on the scene, especially when interpreted in conjunction with its counterpart intensity image, since these two images are complementary in most cases. Moreover, although hyperspectral imaging might be mandatory for recognition of small targets, we evidence that the number of channels can be limited to a set of few wavelengths as far as target detection is considered.
