Abstract
A source discriminator comprises a diffusing surface (10) provided to receive radiant energy over a wide field of view. Radiant energy received is transmitted from the diffusing surface (10) along an optical fiber (12) of a preselected numerical aperture to a radiant energy filter or grating (18). The numerical aperture of the optical fiber is preselected to provide an acceptable half-cone of arrival of radiant energy at the filter or grating (18). From the radiant energy filter or grating (18), the radiant energy passes to photosensors, the output signals of which are used; is the source discriminator system.
