  • High resolution multi-lens imaging device
    Patent number: 6954310
    Abstract: An imaging device (30) can include a plurality of lenses (51, 52, 53, 54) mounted on a multi-dimensional support structure (32), a plurality of optical detectors (40) corresponding to the plurality of lenses for capturing an optical signal from at least two lenses among the plurality of lenses, and a processor (34) for combining the optical signal from at least two lenses to form an image and electronically controlling the field of view and a resolution of the image. The plurality of lenses each can include an array of sub-wavelength apertures or a plurality of photon sieve lenses (36).

  • Small vacuum compatible hyperthermal atom generator
    Patent number: 5834768
    Abstract: A vacuum compatible hyperthermal atom generator includes a membrane having two sides, the membrane having the capability of dissolving atoms into the membrane's bulk. A first housing is furnished in operative association with the first side of the membrane to provide for the exposure of the first side of the membrane to a gas species. A second housing is furnished in operative association with the second side of the membrane to provide a vacuum environment having a pressure of less than 1.times.10.sup.-3 Torr on the second side of the membrane. Exciting means excites atoms adsorbed on the second side of the membrane to a non-binding state so that a portion from 0% to 100% of atoms adsorbed on the second side of is the membrane are released from the second side of the membrane primarily as an atom beam.
