Abstract

High spectral resolution observations of several common camouflages have been made as part of a utility study for a Fourier transform visible hyperspectral imager (FTVHSI). Two types of data were collected. First were non-imaging spectral reflectance measurements made with a spectral resolution better than 0.3 nm over the 350 nm to 1150 nm band. Second were hyperspectrally resolved two dimensional hypercubes of the samples using a FTVHSI. These second data have a spectral resolution of 270 cm^-1 over a band of 370 nm to 1030 nm and a spatial resolution of about 2 cm. The data were taken against representative foliage backgrounds that ranged from grass, to tropical forest vegetation, to an arid mesa. The data show both macro and micro spectral differences between the camouflage and the backgrounds that are apparent in the hyperspectral renditions but missing in broad band observations.
