<p>The device includes a dispersive system (6) and device (11) for complex amplitude modification of the electromagnetic field of the light wave according to a filtering function, which ensures the dilatation of the image in monochromatic light in the direction of spectral dispersion. The dispersive system (14) is a bi-dimensional network. The means (11) is a filter placed in a zone where the luminous wave is dilated. The device itself forms part of a multiplexer/demultiplexer and the network is an holographic network. The multiplexer or demultiplexer has a filter (11) in a zone where the luminous wave is dilated which ensures the control of the devices operation. It has a mirror (9) and a network (8), the optical axis of the mirror (9) crosses the plane of the network and is parallel to the lines on it.</p> |
