  • Patent number: 9622662
    Abstract: A hyperspectral imaging system having an optical path. The system including an illumination source adapted to output a light beam, the light beam illuminating a target, a dispersing element arranged in the optical path and adapted to separate the light beam into a plurality of wavelengths, a digital micromirror array adapted to tune the plurality of wavelengths into a spectrum, an optical device having a detector and adapted to collect the spectrum reflected from the target and arranged in the optical path and a processor operatively connected to and adapted to control at least one of: the illumination source; the dispersing element; the digital micromirror array; the optical device; and, the detector, the processor further adapted to output a hyperspectral image of the target.

  • Patent number: 8988663
    Abstract: Using a hand-held range finding device to range an object in a field of view is difficult due to user-induced jitter. In particular, user-induced jitter introduces uncertainty as to which object in a field of view is actually ranged. Current approaches attempt to mitigate user-induced jitter by requiring a user to mount the hand-held range finding device onto a stabilizing device (e.g., a tripod). However, such approaches require the user to carry additional equipment. Embodiments of the present disclosure enable the user to visually confirm which object in a field of view is actually ranged during a range finding event by generating a composite image that includes a visual representation of a laser pulse emitted by the range finding device reflecting off an object in the field of view. Advantageously, disclosed embodiments provide true hand-held range finding capabilities without requiring the use of stabilization assistance techniques.
