Claim 13:
14. The holographic data retrieval system of claim 13, comprising an output waveguide network, in the form of one or more further multimode optical waveguides, the output waveguide network having an out-coupling region, and multiple in-coupling regions respectively optically coupled with the recording regions of the at least one holographic recording medium,
wherein the controller is coupled to at least one of the emitter system and at least one controllable guiding element of the output waveguide network, and is configured to control:
the at least one guiding element of the output waveguide network, and
the at least one optical characteristic of the reference beam, and thus a corresponding optical characteristic of the output beam,, in order to guide the output beam from the selected recording region, via the in-coupling region optically coupled to the out-coupling region of the output waveguide network for receiving at the detector array, wherein different ones of the recording regions may be read from using the same detector array, whilst the in-coupling regions of the output waveguide network remain at fixed locations relative to the recording regions of the holographic recording medium.
