Marc, nice that you managed to do that. There is also channel 1 (designed
for the fixed-pattern noise correction that we do not use currently), you
may re-use it for processing of the data. It should be not that difficult
to change the direction if needed (it was intended to read fixed-pattern
noise  data from the SDRAM and combine it with incoming sensor data - 8
bits for (scaled) subtraction and 8 bits - for (also scaled:  ( 1+k*data))
multiplications. The multiplicative FPN in the modern sensors is rather
low, we used it when dealing with the MCP image intensifiers with
fiberoptic tapers bonded directly to the sensor chip - in that case the
FPN  modulation was very strong.

Marc, I believe the better place to describe the project would be on the
blog -  there are already several interesting projects described - not just
the ones that we are working on ourselves. The registration on the blog is
closed (because of spam) but we'll be happy to register you and assign
relevant permissions to edit and post there.
