Demonstration: A Photorefractive Correlator for Robotic Applications

Henri Rajbenbach

Recent advances in solid state lasers, liquid crystal spatial light modulators, computer generated holograms, and nonlinear optical materials have opened new opportunities for photonic technologies in the field of parallel processing and computing. To explore some industrial applications of these technologies, the Commission of the European Communities started in 1989 an ESPRIT* project, bringing together, in a precompetitive consortium, industrial partners (Thomson-CSF in France, KRUPP in Germany), a national research center (RISØ in Denmark), and a university (Universitat Erlangen in Germany).
