Abstract

We present a hyperspectral camera based on a Fabry-Pérot interferometer designed to work in the UVA range (315-400 nm). The measured hypercube contains about 400 × 400 pixels, for a total of 160 000 spectra. Each spectrum has a spectral resolution of about 5 nm at the wavelength of 315 nm. Spatial and spectral discrimination capability has been demonstrated by imaging a target with five different ultraviolet (UV) light-emitting diodes. Spectral resolution is demonstrated by aiming at the sky and observing spectral features of the diffused solar light in the UV. A possible application of the hyperspectral camera is the measurement of the UVA content of the diffused light of the whole sky.
