The targets detected in the FOV of the instrument are shown on the right. Due to scaling, not all targets evident in the raw data may be observable in the picture. The scale on the detector array is 0.5 mm/pixel. Figure Legend: From: Classification of visible point sources using hyperspectral chromotomosynthetic imagery J. Appl.

Integrating each spectral projection along the dispersion axis at θ produces the 1-D projection S(t,θ) which is equivalent to taking the radon transform of the undispersed image in which the total energy would be located at the undispersed location. Shown are line projections at θ=0 deg and θ=45 deg. Figure Legend: From: Classification of visible point sources using hyperspectral chromotomosynthetic imagery J. Appl.
