Abstract
A hyperspectral sensor or imager comprising a laser for illuminating a scene and a detector for detecting light emitted by the laser and transmitted through the scene, wherein the laser is a chirped laser arranged to output multiple pulses having different wavelength ranges, the multiple pulses being used to form an extended continuous spectrum for illuminating the scene.

A hyperspectral sensor or imager comprising a laser for illuminating a scene and a detector for detecting light emitted by the laser and transmitted through the scene, wherein the laser is a chirped laser arranged to output multiple pulses having different wavelength ranges, each chirped pulse providing a wavelength scan, and the laser being operable so that the individual wavelength scans of the chirped pulses combine to provide an extended continuous spectrum for illuminating the scene.
