Abstract:
1. A hyperspectral imaging system for providing a hyperspectral image of an area of a remote object, the hyperspectral imaging system comprising: at least one optic configured to receive light associated with the remote object; a scannable slit mechanism comprising a surface configured to receive the light from the at least one optic, and the surface further positioned at an image plane of the at least one optic; the scannable slit mechanism configured to activate at a first time multiple first slits located in multiple positions on the surface, where the activated multiple first slits provide multiple first lines of the light; a spectrometer comprising at least a diffraction grating configured to receive the multiple first lines of the light and provide multiple first diffracted lights; a two-dimensional image sensor configured to receive the multiple first diffracted lights and provide a two dimensional image of the multiple first diffracted lights, and wherein the multiple first slits are separated from one another by a predetermined spectral band so that the multiple first diffracted lights are separated from one another in the two dimensional image of the multiple first diffracted lights; and wherein the scannable slit mechanism comprises a drum with multiple slits formed therein and an actuator that rotates the drum.
