Abstract

The advantages of SWIR imaging in comparison to imaging in the VIS range are twofold: At first, the observation range is higher due to a better transmission of the atmosphere especially under hazy weather conditions. At second, the target contrast is higher in many relevant cases caused by a reflection behavior of objects differing significantly from what we know from the visible. In this lecture, a method is presented which, similar to the tristimulus theory of the eye, creates a SWIR image consisting of 4 individual images. The recordings are made with bandpass filters at the wavelengths of 1000 nm, 1200 nm, 1400 nm and 1600 nm. The complete SWIR spectrum is spectrally resolved from the overlap of the filter curves.
