ABSTRACT:
A sensor for detecting the radio-luminescence created by radioactive sources includes a telescope, a plurality of UV sensitive cameras, and an optical system in the optical path of the telescope for directing images to the cameras. The cameras simultaneously obtain images from a plurality of spectral bands covering strong transitions of N2 molecule created by the radioactive source and at least one spectral band containing very little transition strength (a background band). The background image is used to assess the background level for the other spectral bands. The images are then fused digitally to create one image of the radio-luminescence.
