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.
