This paper presents an adaptive random access image sensor by using histogram equalization based adaptation, this retina can adapt automatically to different lighting conditions without any opto-mechanical adjustment. Expand
Production of mannitol
PURPOSE: To produce mannitol in high yield and at low cost. CONSTITUTION: A process comprises enzymatic isomerizing a fructose syrup containing less then 15% glucose to a mixture containing of… Expand
A programmable artificial retina
An artificial retina is a device that intimately associates an imager with processing facilities on a monolithic circuit. Expand
Optical generation of random-number arrays for on-chip massively parallel Monte Carlo cellular processors.
Stochastic optical phenomena can be used for generation of random-bit arrays with a prescribed probability law that may vary in space and in time. Expand
2-D generation of random numbers by multimode fiber speckle for silicon arrays of processing elements
Abstract We investigate a random-number array generator based on the statistical properties of speckle patterns and we compare the use of (i) two moving diffusers, and (ii) multimode optical fiber… Expand
An adaptive optical sensor
We propose an adaptive optical sensor circuit performing a linear incident-light-to-voltage conversion using the channel-length-modulation effect using a single-poly technology. Expand
Utilisation du “speckle” comme générateur rapide de tableaux aléatoires binaires: Optimisation des paramètres
RésuméProjeté sur un réseau monolithique bidimensionnel de capteurs photosensibles, à parallélisme massif, le speckle peut être utilisé pour générer des nombres binaires aléatoires obéissant à une… Expand
Optical cellular processor architecture. 1: Principles.
General characteristics and advantages of 2-D optical cellular processors are listed and discussed, with reference to the concepts of cellular automata, symbolic substitution, and neural nets. The… Expand
Optical cellular processor architecture. 2: Illustration and system considerations.
In the first paper of this series, we proposed a definition for the concept of 2-D optical cellular processors. In this second part we present an optical experimental setup capable of implementing a… Expand
A pyramidal system for image processing
Because of the large volume of data handled during image analysis, a high degree of parallel processing is required in special purpose image processing computers. Expand
