ACTIVE HYPERSPECTRAL IMAGING WITH A LASER ILLUMINATOR AND WITHOUT DISPERSION

Hyperspectral imaging is carried out by utilizing a set of lasers to illuminate a scene containing a sample in a series of successive laser illuminations by turning on at least one laser in the set of lasers for each successive illumination in the series. Here, each laser generates a known wavelengt...

More Information
Summary:Hyperspectral imaging is carried out by utilizing a set of lasers to illuminate a scene containing a sample in a series of successive laser illuminations by turning on at least one laser in the set of lasers for each successive illumination in the series. Here, each laser generates a known wavelength of light. Imaging is further carried out by utilizing a camera to capture an image of the scene during each successive laser illumination, thus generating a series of successive images. However, no dispersive element is utilized between the scene and the camera. Imaging is still further carried out by processing the captured images to produce scene data. The scene data is compared with target profiles to determine whether the scene includes at least one target of interest and taking a predetermined action in response to detecting at least one target of interest.
