Real-time digital-optical correlator-systems design
The systems design of a real-time hybrid digital-optical correlator is detailed. Emphasis is on: partitioning of the digital and optical systems such that the efficiency of the optical image train is maximised; and the parallelisation of tasks within the digital sub-system to maximise throughput. The significance of communication bottlenecks are emphasised in the digital system and the constraints this enforces on the initial selection of DSP devices. (C) 1999 Elsevier Science B.V.
