Paper Abstract

3D superposed holograms of co-orthogonal wave fields are investigated. Two operations were performed when using these holograms. One of them presents the expansion of the wave field of the object in set Walsh functions. The mentioned hologram was also used for switching of optical channels. The objects were presented by a set of 7 luminous points having different phases. Wave fields of the objects were expanded in a set of 8 Walsh functions. Complex amplitudes of the object waves were calculated from the measured coefficients of expansion. The switching of one input optical channel to 8 output channels was accomplished by phase modulation of incoming wave corresponding to Walsh functions values.
