Transmission d’images en couleurs dans des fibres optiques par codage polychromatique

Abstract

Color image transmission through a 1-D array of 150 parallel multimode optical fibers is demonstrated using chromatic encoding of both geometric and spectral structures of self-luminous incoherent sources. The spectroscopic encoding and decoding devices include infrared type echelette gratings working at high diffraction orders in the range of the visible wavelengths considered in these experiments (~0.45-0.75, microm). Very good image and color quality was achieved: 2.5 x 10(4) pixels, seven spectral components per pixel.
