A hyperspectral imaging system comprising: a fore optic configured to receive an image from a remote object, said image including a plurality of lines of light; a scannable slit mechanism comprising a disk that includes a first slit comprising a plurality of portions, wherein each portion is for receiving a line of light and has a height that is equal to or larger than a height of the image, and a second slit comprising a plurality of portions, wherein each portion is for receiving a line of light and has a height that is equal to or larger than a height of the image; said first slit and said second slit being positioned so that said fore optic projects said image to simultaneously illuminate a first portion of said first slit and a first portion of said second slit, said first portion of the first slit receiving a first line of light from said fore optic and outputting a trimmed first line of light, said first portion of the second slit receiving a second line of light from said fore optic and outputting a trimmed second line of light, said first line of light originating from a first portion of said remote object and said second line of light originating from a second portion of said remote object; a spectrometer with dispersing device, said spectrometer positioned to receive and disperse said trimmed first line of light to produce a dispersed first line of light, said spectrometer positioned to receive and disperse said trimmed second line of light to produce a dispersed second line of light; a two-dimensional image sensor with a plurality of detection elements, said two-dimensional image sensor positioned to receive said dispersed first line of light over a first set of said detection elements and to receive said dispersed second line of light over a second set of said detection elements, said two-dimensional image sensor configured to obtain a two-dimensional image of said dispersed first line of light and a two-dimensional image of said dispersed second line of light; and an actuator configured to reconfigure said scannable slit mechanism, said reconfiguration including repositioning said first slit and said second slit; characterised in that the actuator is configured to reposition said first slit and said second slit such that said first slit and said second slit remain continuously simultaneously illuminated by said image during said repositioning, said repositioning situating a second portion of the first slit to receive a third line of light from said fore optic and a second portion of said second slit to receive a fourth line of light from said fore optic, said third line of light originating from a third portion of said remote object and said fourth line of light originating from a fourth portion of said remote object. a fore optic configured to receive an image from a remote object, said image including a plurality of lines of light;
