The optical feature extractor is a photorefractive ring oscillator that can identify the strongest
spatio-temporal component of its input space. The theoretical sections discuss the design …

Real-time edge-enhanced image correlation using the incoherent readout of a dynamic
hologram recorded in BSO crystal is reported for the first time. A system is described which …

A modified real-time holographic technique for obtaining high fidelity integration of coherent
or incoherent signals is described. The technique maintains the sensitivity, resolution, and …

We report measurements of the photorefractive phase shift and coupling constant of several
photorefractive materials. We solve the problem of beam coupling and diffraction in a …

A photorefractive interconnect system with coherently erasable synapses (PISCES) is
described. Comparing holographic erasure by intensity and phase modulation of the writing …

Real-time rotational invariant pattern recognition is demonstrated using the method of
circular harmonic filtering (CHF) in a photorefractive crystal such a BaTiO 3 to perform …

We demonstrate a self-organizing photorefractive circuit that demultiplexes a beam that has
two signals imposed on separate optical carrier frequencies into two beams, each …

In this letter we present a technique which employs a photorefractive lithium–niobate crystal
for novelty filtering. Due to the minimal trail formation exhibited by this novelty filter, it can be …

We present and demonstrate a set of dynamic optical interconnects which are based on the
double phase conjugate mirror with photorefractive wave mixing. These devices are …
