1. A warning receiver, comprising:
a first anamorphic lens positioned to receive light within a field-of-view (FOV) defined by first and second scene spatial angles that are orthogonal to each other and to compress the light along the first scene spatial angle into a single line of light along the second scene spatial angle;
a first dispersive element positioned to separate the single line of light into a plurality of wavelengths orthogonal to the second scene spatial angle to produce a two-dimensional light field indexed by the second scene spatial angle and wavelength;
a pixelated detector positioned to receive the two-dimensional light field and readout electrical signals indexed by the second scene spatial angle and wavelength; and
a processor coupled to the pixelated detector to process the electrical signals indexed by the second scene spatial angle across a wavelength spectrum of the single line of light to detect and characterize an optical source within the FOV.
