Abstract

We present an optical device for hyperspectral imaging designed to work in the 300-400 nm range. The system is basically based on a scanning Fabry-Pérot interferometer with reflective mirrors in the range of interest. The instrument allows capturing the UV spectrum of each pixel of an image generating a 3D matrix called “hyperspectral cube” with spatial and spectral information. This system can be integrated with a digital camera provided with a UV sensitive sensor and a UV fisheye optic for the measure of the UV sky radiance.
