  • Patent number: 12022172
    Abstract: A multi-spectral imaging system utilizing tunable optics is disclosed. Various disclosed systems include a tunable optical filter coupled to a broadband imaging system. The tunable optical filter allows discrete infrared wavelengths to pass to the broadband imaging system so that monochromatic infrared images of a scene may be captured. An image processing system may process selected monochromatic infrared images by using a ratio technique to generate an emissivity-independent thermal image of the scene. The tunable optical filter may also be used to adjust a quality factor and control an amount of radiated energy that is passed to an image sensor of the broadband imaging system thereby acting as an aperture to account for both low and high radiance portions of the scene.

  • Patent number: 11980100
    Abstract: A metal junction thermoelectric device includes at least one thermoelectric element. The thermoelectric element has first and second opposite sides, and a first conductor made from a first metal, and a second conductor made from a second metal. The first and second conductors are electrically interconnected in series, and the first and second conductors are arranged to conduct heat in parallel between the first and second sides. The first metal has a first occupancy state, and the second metal has a second occupancy state that is lower than the first occupancy state. A temperature difference between the first and second sides of the thermoelectric element causes a charge potential due to the difference in occupancy states of the first and second metals. The charge potential generates electrical power.
