Dual band hyperspectral imaging spectrometer |
| abstract |
A dual band spectrometer ( 40 ) for imaging one or two spectral bands onto a common image plane. The spectrometer ( 40 ) includes an input aperture ( 42 ) for receiving scene photons; an entrance slit ( 46 ) illuminated by photons from the input aperture ( 42 ); a diffraction grating ( 50 ) for dispersing the photons into spectral bands, such that at least one of the spectral bands embodies two diffraction orders; a collimator ( 48 ) for collimating the photons from the input aperture ( 42 ) and directing the photons toward the diffraction grating ( 50 ); an image plane ( 60 ) receiving the at least one spectral component from the diffraction grating ( 50 ); and an order sorting filter device ( 54 ) interposed between the diffraction grating ( 50 ) and the image plane ( 60 ), such that the filter device ( 54 ) is operable to pass only one of the two diffraction orders onto the image plane ( 60 ). |
