Real-time digital-optical correlator-sytems design

摘要

The system 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 rain 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.
