Claim One:
1. A hyperspectral imaging system, comprising: a focal plane array; a grating-free spectrometer for dividing a field of view into multiple channels as bars and for reimaging the multiple channels as multiple spectral signatures onto the focal plane array, the grating-free spectrometer having: first optics for collimating electromagnetic energy of an object along an optical axis; a first prism for dispersing the electromagnetic energy; a second prism for redirecting the spectra of the first prism along the optical axis; and second optics for focusing electromagnetic energy along the optical axis from the second prism and onto the focal plane array, and a processor connected with the focal plane array for forming a hyperspectral data cube from the multiple spectral signatures, wherein objects may be identified from the hyperspectral data cube.
