OK, last question I promise...

Where does the spectral sensitivity peak in the luminance array? (I'm assuming
that the response is broad enough to cover all colour channels) Is s/n
performance affected by filtration applied at the light source?

rectangle pixels, and we can spatially process  each individual pixel into
any shape ( Square or rectangle ) and any reolution and in real time (
which is vey fast signal processing ). The spatial processor is a quite
advanced piece of technology .<

I have some experience of frequency space operations, what kind of transform
is employed by your spatial processor?
