A multimode fiber sensor using the intensity inner product of speckle fields is presented. The sensitivity and the dynamic range of the displacement sensing are quantitatively analyzed. We show that… (More)
The implementation of non-zero-order joint-transform correlators (JTC's) is presented. The zero-order spectra (i.e., the autocorrelation power spectra) are removed from the joint-transform power… (More)
A joint transform correlation system based on optical disks is presented. The operation principle, system considerations, and processing speed are discussed.
This paper investigates a neural network model-interpattern association (IPA) model-in which the basic logical operations are used to determine the interpattern association (i.e., association between… (More)
A compact optical neural network that uses high-resolution liquid-crystal televisions has been constructed. System design considerations and an experimental demonstration of the liquid-crystal… (More)
Recently, many applications of the liquid crystal television (LCTV) to real-time signal processing have been reported. A basic description of the application of the LCTV to realtime pattern… (More)
A study of the effect of fringe binarization on the joint transform correlator has shown that the interference fringes for multiple targets could produce false alarms and misses.
A microcomputer-based programmable optical correlator (MPOC) is proposed for automatic pattern recognition and identification. A programmable magneto-optic spatial light modulator and a… (More)
We present a fiber-sensing technique that detects the mean-absolute speckle-intensity variation between the updated and the reference speckle pattern for determining the environmental perturbation… (More)
