action: Notice of government owned inventions available for licensing.

-----------------------------------------------------------------------

summary: The inventions listed below are owned in whole or in part by 
the U.S. Government, as represented by the Department of Commerce. The 
Department of Commerce's ownership interest in the inventions is 
available for licensing in accordance with 35 U.S.C. 207 and 37 CFR 
Part 404 to achieve expeditious commercialization of results of 
Federally funded research and development.

for further information contact: Technical and licensing information on 
these inventions may be obtained by writing to: National Institute of 
Standards and Technology, Office of Technology Partnerships, Building 
820, Room 213, Gaithersburg, MD 20899; Fax 301-869-2751. Any request 
for information should include the NIST Docket No. and Title for the 
relevant invention as indicated below.

supplementary information: NIST may enter into a Cooperative Research 
and Development Agreement (``CRADA'') with the licensee to perform 
further research on the inventions for purposes of commercialization. 
The inventions available for licensing are:
    NIST Docket Number: 97-015US.
    Title: Noise Reduction In Volume Holographic Memories.
    Abstract: A method for improving the quality of holographic images 
by reducing local noise in a holographic memory system is disclosed. 
The method is characterized by: storing a white reference image and a 
black reference image in the memory system, storing a series of data 
images in the memory system, applying a simple model based on a point-
to-point of linear interpolation to the series of data images, the 
white reference image and the black reference image to provide a series 
of corrected data images having reduced noise. The simple model is 
preferably in a form which is characterized by temporal stability for 
the series of data images for each set of the black and white reference 
images.

    NIST Docket Number: 97-045US.
    Title: Granting Assisted Acousto-Optic Tunable Filter and Method.
    Abstract: Dense wavelength division multiplexing (D-WDM) is 
promising in future information networks to increase the communication 
bandwidth. The invention is an acousto-optic tunable filter that can 
increase the number of channels significantly by combining a 
diffraction grating with an acousto-optic spectrum analyzer. The novel 
grating-assisted acousto-optic tunable filter (GA-AOTF) allows a very 
narrow spectral bandwidth (only 5% of those of conventional AOTFs) 
resulting in a significant increase in bandwidth and available channels 
by a factor of approximately 20.
