  • Patent number: 10989602
    Abstract: A recessed carbon nanotube article includes a base; a substrate disposed on the base; wells disposed in the substrate and bounded by the base and a substrate wall; and a carbon nanotube element disposed in individual wells and including vertically aligned carbon nanotubes such that a longitudinal length of the vertically aligned carbon nanotubes is less than a depth of the well in which the carbon nanotube element is disposed. A recessed carbon nanotube bolometer includes a base; a substrate on the base; radiation wells in the substrate; carbon nanotubes in the wells; thermistors and heaters on the membrane arranged as an electrical substitution member. A process for making a recessed carbon nanotube bolometer includes forming a substrate on a base; forming a radiation well in the substrate; forming carbon nanotubes in the well; disposing a cover on the wells; and forming a thermistor and a heater on the base.

  • Patent number: 10234309
    Abstract: A photon momentum sensor includes: a reflector plate that includes: a central disk including a mirror; an annular member; a plurality of spring legs interposed between the central disk and the annular member, such that: the spring legs are interleaved; neighboring spring legs are spaced apart; and the spring legs individually are arranged in an Archimedean spiral that provides orthogonal motion of the central disk relative to the plane of the annular member; and a bias plate disposed opposing the reflector plate such that: the central disk of the reflector plate moves orthogonally to a plane of the bias plate in response to reflection of laser light, and the central disk and the bias plate are arranged spaced apart as a capacitive structure.

  • Patent number: 9291499
    Abstract: A radiometer includes a substrate; a radiation absorber disposed on the substrate to absorb radiation; a thermal member disposed on the substrate to change electrical resistance in response to a change in temperature of the radiometer; and a thermal link to connect the radiometer to a thermal reference, wherein the radiation absorber, the thermal member, or a combination comprising at least one of the foregoing includes a plurality of carbon nanotubes, the carbon nanotubes being mutually aligned with respect to the substrate, and the radiometer being configured to detect optical power.
