Pr. Fossum,Thank you for this very interesting presentation. In particular I find the concept of QIS most interesting. For me the challenge is probably more in the photodetector than in the associated electronics. You consider the data transfer as a big challenge, but dont you think possible to resort to on-chip data reduction (image formation) and on-chip networking, rather than moving out Tbits/s of data ? What is in your mind the timeframe for the realization of the QIS ?
