Cellular neural networks (CNNs) consist of analog, nonlinear, dynamic processing elements which are locally interconnected. Most applications in the areas of image processing, pattern recognition and robot control require interconnections between all

We present an optical feature extraction system with a microlens array processor. The system is suitable for online implementation of a variety of transforms such as the Walsh transform and DCT. Operating with incoherent light, our processor accepts

We present a hybrid shape recognition system with an optical Hough transform processor. The features of the Hough space offer a separate cancellation of distortions caused by translations and rotations. Scale invariance is also provided by suitable n

A highly accurate measurement technique has been developed and applied for characterization of the complex transmittance of liquid crystal light valves (LC-LV). The measurement setup is based on a two-beam interference with partially coherent light.

Optical signal processing systems frequently use Fourier transform techniques for correlation, filtering, etc. In practical applications the complex-valued filters placed in the frequency domain plane are often realized by a liquid crystal spatial li

A simple optical system is described which allows for the variation of the viewing angle of transmissive-type LCDs. It is well suited for automatic teller machines (ATMs) to switch between a wide viewing angle state which is defined by the used LCD a

Tritium that was not present in the original water sample (“blank”) is observed when measuring tritium concentrations which are near analytical detection limit (in this laboratory about ±0.08TU, or ±0.26pCi/1 of water, 1σ). The analytical blan
