Acousto-Optic Processing of 2-D Signals Using Temporal and Spatial Integration( Book )

4 editions published between 1986 and 1989 in English and held by 4 WorldCat member libraries worldwide

The report describes research to develop acoustooptic information processing systems capable of processing two dimensional signals. The general methodology that was developed for accomplishing this, is the use of a combination of temporal and spatial integrations in the optical system. Acoustooptic processors for synthetic aperture radar image formation were designed and experimentally demonstrated. The radar imaging processor is capable of forming images in real time with relatively low size and power requirements. Several processors were also developed for pattern recognition applications and an acoustooptic system capable of producing two dimensional correlations of images at standard video rates was experimentally demonstrated. The same signal processing method was applied to two dimensional spectrum analysis and the processing of signals from broadband adaptive phased arrays. In both instance acoustooptic architectures were developed and initial experimental demonstrations were performed

Holographic Random Access Memory by Demetri Psaltis( Book )

3 editions published in 1997 in English and held by 2 WorldCat member libraries worldwide

We designed and demonstrated a fully working, large-scale random-access holographic memory. The recording medium is a Fe-doped LiNb03 photorefractive crystal. The storage capacity of the memory is limited by the dynamic range and geometric limitation. The number of holograms stored at a certain location in the crystal is mainly limited by the dynamic range. To further increase the storage capacity, holograms can be stored at different spatial locations in the crystal. The total number of storage locations is restricted by the geometric limitations of the optical system. Three multiplexing techniques -- angle, fractal and spatial multiplexing are employed to superimpose multiple holograms in the recording medium with the help of a custom-designed segmented mirror array. The memory consists of 16 vertically spaced locations on the recording medium, a LiNb03 crystal, each containing 10,000 holograms. The data storage on each of the 16 locations is organized as 4 fractal multiplexed rows of 2,500 angularly-multiplexed holograms. We successfully demonstrated the storage of 160,000 holograms in the system by recording 10,000 holograms on each of the top, center, and bottom storage locations and 1,000 holograms on each of the 16 locations. We achieved an average bit-error probability on the order of 10%(A). By using an acousto-optic deflector (AOD) as the angle scanner, we achieved a random access time in the order of 100 microseconds to the 1,000 holograms stored by angle multiplexing. In the latest progress towards a practical non-volatile memory system, we recorded and thermally fixed 1,000 holograms with no degradation in the error perlormance

Large Scale Spectral Hole Burning Memory in Organic Materials( Book )

2 editions published in 2002 in English and held by 1 WorldCat member library worldwide

Spectral hole burning is one special holographic technology, which requires to cool down the holographic material down to liquid helium temperature -270 degree of Celsius. However, it can record and generate very fast optical light pulse series and their interaction. Spectral hole burning is of critical interests for fast data storage and optical information processing. This work would be used to evaluate and study the general properties of the materials used for these application. This research is sponsored by the Air Force Office of Scientific Research under grant# F49620-99-1-0258
Monolithic Optoelectronic Implementation of Neural Planes( )

2 editions published between 1991 and 1992 in English and held by 0 WorldCat member libraries worldwide

The implementation of a neural computing system, whose structure and function is motivated by natural intelligence, will provide a unique way to solve problems that are typically too difficult for the conventional electronic computers to tackle. Interest in this type of computer has emerged largely because it is hoped that by building a computer that shares some of the characteristics of the biological systems, we will be able to address problems such as image recognition which animals do exceedingly well but current computers do not. There has been considerable progress on the theoretical research in neural network to justify the optimism of future applications. This has resulted in a focused attention on the hardware realization of neural architectures. The computational power of neural computers arises from matching the computer architecture and the physical properties of the devices used in the implementation to the requirements of the problem
3-D Optical Memory Disk by Demetri Psaltis( Book )

3 editions published between 1993 and 1994 in English and held by 0 WorldCat member libraries worldwide

Recently, a new method of multiplexing holograms by rotating the material, or equivalently, the recording beams was invented. This method is called Peristropic (Greek for rotation) multiplexing and is briefly described. Peristropic multiplexing can be combined with other multiplexing methods to increase the storage density of holographic storage systems such as the previously reported 3-D disk. Peristropic multiplexing was experimentally demonstrating using DuPont's HRF-150 photopolymer film. A total of 395 holograms were multiplexed in the 38-micrometer thick photopolymer disk by combining peristropic multiplexing with angle multiplexing. In addition, it is shown that combining both angle and peristropic multiplexing the storage density of 3-D disks is greatly enhanced
