True 3D holography is a very attractive target from user point of view, but the technologies available today are still quite far from that ideal target. One of the major bottlenecks, next to the actual photonic transducer, is to effectively distribute the huge amount of streaming input control data to the massive array of individual imager cells. The latter are targeted to be 100 nm square, so the space available for this data distribution circuit is very limited. Moreover, it should be cheap to address a broad market of embedded applications, sufficiently high speed to deliver the required ...
