Interesting question. Linear with respect to what? Intensity of a
single color? Or over what wavelength span? By what measure?
Output vs. input, in what units? Before or after A to D conversion?
Do you place the blame on the A side, the D side or in between? Or am
I missing the point entirely? The CCD sensors favor Green over Red
and Blue. Does this enter the picture (pun intended)?

Robert,
Given that, why would we care a whole lot about the devices we use
being
linear?
Because I don't believe it and I think students should also question
such "absolutes" so I just wanted to be more confident myself that I
was not totally out in left field so to speak!
