Fig. 1From: Characterization of the angular response of a multi-directional spectroradiometer for measuring spectral radianceScheme of the multi-directional entrance optics (MDIO) of AMUDIS system. 435 optical fibres are distributed on the dome pointing at 145 different directions of the sky. At the end of the optical fibre bundle. the fibres are vertically aligned on a slit which can be connected to the spectroradiometerBack to article page
