Patents by Inventor Albert J. Sievers

Albert J. Sievers has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6930781
    Abstract: A digitally aberration corrected miniaturized holographic Fourier transform spectrometer (HFTS) made from simple optical components and with no moving parts is provided. The disclosed digitally aberration corrected HFTS is comprised of a two beam interferometer, which provides two interfering beams; a 2D array detector to detect the interference pattern created by the beams; a computer for correcting effects of aberrations in the pattern and calculating the spectrum from thus corrected interferogram.
    Type: Grant
    Filed: November 25, 2003
    Date of Patent: August 16, 2005
    Assignee: Cornell Research Foundation, Inc.
    Inventors: Nikolay I. Agladze, Albert J. Sievers

  • Patent number: 5206083
    Abstract: Novel diamond thin films deposited on a metal or ceramic composite comprising a matrix having dispersed therein finely divided diamond or diamond-like particles are useful in improving the erosion resistance of materials used for long wave infrared transmitting applications such as domes and infrared windows.

  • Patent number: 5183602
    Abstract: New composites useful for infrared transmitting applications comprise a dispersion of small particles of diamonds in a matrix having infrared transmission properties (from about 1 to at least 10 .mu.m wavelength) and refractive index substantially similar to that of diamond. The composites exhibit mechanical toughness and durability 2-4 times that of the similarly treated matrix alone without adverse effect on optical properties.
