Abstract:
1. A hyperspectral imaging system for providing a hyperspectral image of a two-dimensional area of a remote object, the hyperspectral imaging system comprising: at least one optic configured to receive light associated with the remote object; a disk with a plurality of straight slits formed therein, where the disk comprises a surface configured to receive the light from the at least one foreoptic, and where the surface is further positioned at an image plane of the at least one optic; an actuator that rotates the disk; a controller configured to control the actuator such that the disc is rotated so a first straight slit of the plurality of straight slits is positioned to allow a first line of light associated with the remote object to pass there through; a spectrometer comprising at least a dispersion device configured to receive the first line of light and output a first dispersed line of light; a two-dimensional image sensor configured to receive the first dispersed line of light and provide a first two dimensional image of the first dispersed line of light; the controller configured to obtain the first two dimensional image and control the actuator such that the disc is rotated so a second straight slit of the plurality of straight slits is positioned to allow a second line of light associated with the remote object to pass there through; the spectrometer comprising at least the dispersion device configured to receive the second line of light and output a second dispersed line of light; the two-dimensional image sensor configured to receive the second dispersed line of light and provide a second two dimensional image of the second dispersed line of light; and the controller configured to obtain the second two dimensional image.
