Image-based holographic stereogram rendering methods for holographic video have the attractive properties of moderate computational cost and correct handling of occlusions and translucent objects. These methods are also subject to the criticism that (like other stereograms) they do not present accommodation cues consistent with vergence cues and thus do not… (More)
We study the joint optimization of time and space resources withinfree-space optical interconnect (FSOI) systems. Both analyticaland simulation results are presented to support this optimization studyfor two different models of FSOI cross-talk noise: diffraction froma rectangular aperture and Gaussian propagation. Under realisticpower and signal-to-noise… (More)
At high bit rates, four-wave mixing and nonlinearities in the optical channel give rise to ghost pulses. In this letter, we propose the application of modulation codes to tackle this effect.
An imaging system is proposed as an alternative to metallized connections between integrated circuits. Power requirements for metallized interconnects and electrooptic links are compared. A holographic optical element is considered as the imaging device. Several experimental systems have been constructed which have visible LEDs as the transmitters and PIN… (More)
A forward-error correction )FEC) scheme based on low-density parity check (LDPC) codes and iterative decoding using belief propagation in code graphs is presented in this paper. We show that LDPC codes provide a significant system performance improvement with respect to the state-of-the-art FEC schemes employed in optical communications systems. We present… (More)
A factorial design approach to optimizing rehalogenating bleaches for silver halide holograms is presented. An advantage of this technique is that it allows simultaneous improvement in a number of hologram performance characteristics as a function of several input parameters. Interactive effects of combinations of input parameters can also be examined. A… (More)
Holographic gratings formed in thick phenanthrenquinone- (PQ-) doped poly(methyl methacrylate) (PMMA) can be made to have narrowband spectral and spatial transmittance filtering properties. We present the design and performance of angle-multiplexed holographic filters formed in PQ-PMMA at 488 nm and reconstructed with a LED operated at approximately 630 nm.… (More)
The alignment and chromatic sensitivity of holographic optical elements for use in optical interconnect systems are quantified. The effects of these image degrading parameters are related to the frequency and power requirements for CMOS compatible detectors in an optical interconnect system. Techniques for reducing the magnitude of these problems with… (More)
The polarization properties of cascaded substrate-mode holographic optical elements are analyzed and demonstrated. The design criteria for polarization selective and nonselective elements are given and verified with experimental volume holograms formed in dichromated gelatin emulsions. Using the experimental grating parameters, it is estimated that a… (More)
We present a simple technique for observing and studying the onset of microstructure in silver halide gratings, which can also be used to improve processing chemistry.
