The optical mixing-demixing is effected, as regards the mixing operation, by suitably sending two light beams having different wavelengths to a first separation surface between transparent materials having suitable behaviours of the refractive index. The obtained multiple beam, with a third beam having a different wavelength is then sent to a second separation surface between transparent materials having different suitable behaviours of the refractive index, obtaining an only beam; the operation is repeated till all the beams are mixed. For demixing operation, the beam formed by a plurality of beams, having different wavelengths is suitably sent to a first separation surface between transparent materials having suitable behaviours of the refractive index and an only monochromatic beam is drown out. The resulting beam is then sent to a second separation surface between transparent materials having different suitable behaviours of the refractive index, for drawing out a second monochromatic beam; the operation is repeated until all the beams are demixed. |
