Abstract
The embodiment of the invention disclosed herein is directed to an angle of arrival source discriminator for determining both the spectral content of incident radiant energy and for simultaneously determining the angle of arrival of said incident radiant energy. The discriminator system includes first and second planar detector means positioned adjacent one another and arranged to have their planar surfaces transversely positioned to one another. Connected to the planar detector means are signal receiving and indicating devices, such as ammeters, or the like, for producing output signals in response to the angle of incidence of radiant energy impinging upon the planar surfaces thereof. A diffraction grating is positioned adjacent the planar detector means and oriented substantially at 45.degree. relative to the planar detector means so that signal information impinging on the planar detector means can be compared by analog or digital circuitry to determine both the angle of arrival of the radiant energy and the wavelength thereof.
