conference on algorithms, devices, and systems for optical information processing

In this paper, a substrate-guided-wave-based Perfect Shuffle (PS) having an 8-to-8 interconnection is demonstrated at 632.8 nm wavelength. Sixteen waveguide holograms are fabricated on a planar waveguiding plate with the full functionality of the PS. The diffraction efficiencies of the waveguide holograms are all within 80% +/- 5%. The planar architecture combined with the surface-normal configuration of the demonstrated PS makes the integration with vertical cavity surface emitting lasers (VCSELs) and other surface mountable processing elements highly feasible.

A recursive formula expressing N-dimensional convolutions/correlations via (N - 1)-dimensional ones is proposed. It can serve as a basis for implementing N-dimensional pattern recognition optically. Also a constant time optical algorithm for constructing N-dimensional convex hull and Voronoi diagram (which are widely used in pattern recognition) is proposed.

A novel compact planar configuration for correcting the asymmetric divergence of light emanating from diode lasers is presented. It is comprised of two holographic lenses that are recorded on one transparent substrate, where the light propagates from one lens to the other by means of total internal reflections. The design of the overall planar configuration is presented along with experimental results. The results reveal that it is possible to focus a collimated asymmetric beam to a circular spot.

ISBN: (纸本)0819425818

This paper describes algorithmic development toward an automated process that generates a same patient sequence of fundic images that are normalized in position and intensity and have noise artifacts removed. Normalization of these fundic images is a key first step to further automatic analysis for the presence or progress of ophthalmic diseases. The Litton PRC team, inclusive of Litton Data systems and Tomey Inc., evaluated the potential use of a hybrid optical/digital processor in the normalization of ophthalmic imagery. PRC provided the funding, initial architecture and approach for disease analysis using the optical processor. Tomey Inc. provided the fundus imagery and clinical advice on ''normalization'' of images prior to undertaking the disease analysis. Litton Data systems prototyped the algorithms and tests using a rapid application prototyping tool for object recognition. The team approach was to do a coarse vessel alignment to bring the images within a to-be-determined level of alignment, and then repeat the algorithms at a threshold and alignment for fine vessels. The success of the coarse work encouraged the investigation of algorithms for processing higher resolution images with greater accuracy. The combined results completed the IRAD investigation and are shown as successfully aligning two images.

The application of volume M-type holograms for building multichannel geometries in pattern recognition systems is considered. The results of theoretical and experimental investigations of the hologram's parameters as a function of their recording parameters and their use as filters in correlation setups are presented. Multichannel correlation schemes where the processed signals have either different or the same wavelength are proposed. We have shown that all the correlation schemes proposed allow one to increase data throughput several times over single-channel BR-based correlators.

ISBN: (纸本)0819425818

The search for a dynamic recording medium that can be used in real time without the need for processing has become a critical issue in the development of practical neural network systems, correlators, all-optic switches, image and signal processors, and optical storage (including 3-D) devices. A typical optical material responds to changes in the intensity, polarization, or wavelength of the illuminating light. The optical material developed and used for neural network applications responds to changes in the polarization of blue or green laser (Ar+) light. Implementing a neural network or performing optically-controlled acoustic beam steering requires a high-speed read/write/erase optical memory. POC's erasable dye polymer (EDP) material offers a high read/write/erase data rate, nondestructive reading, fast data access, high storage density, overwrite capability, and long cycle life.

ISBN: (纸本)0819425818

Several designs for a reduced resolution optical correlator are proposed. The design of reduced resolution filters by multiresolution wavelet analysis (MWA) or by downsampling is extended to spatial light modulators with fill-factors less than one. A reduced resolution optical correlator is constructed based on one of the above designs, and a comparison of MWA and downsampling filters is performed for different size targets. The experimental results show good qualitative agreement with simulation;however, the first-order correlation peaks were found to be greater for the experimental results. A possible reason for this is suggested and a new technique for measuring the fill-factor is proposed.

Volumetric memories based on the extension of conventional (e.g.-CD and DVD) approaches by using the third dimension for multiple layers may offer dramatic increases in storage capacity. For such thick-media multilayer systems, the design of the optical head includes challenges in the control and tolerancing of aberration accumulation throughout the focal depth. In this paper we review the accumulation of these aberrations in high resolution thick (>5 mm) disk media, and compare the tradeoffs associated with several aberration compensation techniques. Both analytical and simulation results of aberration accumulation as a function of the system f-number will be presented. Aberration compensation tradeoffs including compensator complexity, cost, compensation range, speed will be detailed. Simulation results of a compensation technique will be presented.

ISBN: (纸本)0819425818

This paper describes novel multiple quantum well optical modulators in which the optical modulation is achieved by field dependent birefringence in strained MQW layers. The modulator operates under normal incidence. In our study, field dependent birefringence is obtained by straining the MQW layers using Surface Acoustic Waves (SAW). Computations of refractive index change, absorption coefficient and contrast ratio are presented. The devices are being fabricated using lattice matched InGaAsP(1.55 mu m well)/InGaAsP(1.3 mu m barrier) layers on InP substrates. The polarization-sensitive Birefringent Spatial Light Modulators (BSLMs) are different from conventional multiple quantum well SLMs and self electro-optical devices (SEEDs) which generally utilize electro-absorption.

Certain optical image processing schemes proposed over the years are severely limited in performance because optical intensity distributions produced by the associated processors are characterized by extremely low signal-to-bias ratios (SBR). The available dynamic range of standard (e.g., CCD) image detectors is used up primarily by the bias content of the distributions, with little dynamic range left over for information-bearing signals. Examples arise in connection with incoherent holography, time-integration acousto-optical spectrum analysis and correlation, and OTF synthesis, as well as in other areas. What is needed for the processing of such low SBR image distributions is an imaging device that is essentially ''ac-coupled,'' i.e., that rejects background bias components in low-contrast imagery and responds only to the signal components. The pyroelectric imaging camera, used traditionally for thermal imaging, has these characteristics if the bias components are non-time-varying and the signal components are made to change with time. Recent developments in pyroelectric materials and camera technology suggest that image processor outputs with SBRs of 10(-3) or less (the human eye is incapable of discerning signal information in such law-contrast imagery) can be detected with 8 to 14 bits of dynamic range going to the signal information alone. Thus, high SNR processing with low SBR signals appears possible. We describe briefly the operation of pyroelectric detectors and cameras and then introduce a variety of real-time image processing applications.
