Velocity in the receiving field is varied between 10 and 100. Duration of pulses is approx. 2 ms, sample rate was 5kHz. Variation of the delay of one channel. And they show, that neural nets can carry information in an optical way.
Black pixels pulse one times.
Analysing the excitement map of the detector space it is not possible to decide, which neurone has fired from which field. Superimposition with variation of channel positions Projections into different fields. Note, that the resulting projections are topologic. It is not possible, to destroy the graph anyway. Finally this picture answers closest the introductionary question in the textual part.
