A device for the production of holographic reconstructions having light modulators is disclosed. An apparatus includes a radio frequency identification tag having a first state in which a carrier signal from a reader does not activate the radio frequency identification tag and a second state in which the carrier signal from a reader does activate the radio frequency identification tag to allow retrieval of information stored on the radio frequency identification tag by the reader. The control center transmits to the terminal a selection information item which indicates which of the two above codings is used in the transmitted information. The channel extensions include first and second releasing openings. Then, the optical plate and the optical block are simply and highly accurately combined by being fitted together by means of fitting sections. The incoming data stream may be a scrambled SONET or SDH data stream.
