Image Scanning --
Like photo scanners and fax machines, spectral cameras and AISA instruments are line imaging instruments - spectral information is only imaged one line at a time across your object or scene.
In airborne instruments, the motion of the aircraft traces out the 2nd spatial dimension over time - a pushbrooming instrument.
To use spectral cameras in from a stationary ground point, laboratory, or other static situation, the object or the camera's field-of-view has to be linearly scanned.
The scanner add-on provides the single axis movement to trace out spatial images with full spectral information - 3-dimensional spectral data cubes.
