curve is tolerant for external pixel offset error correction. This
means that pixel offset variations can be corrected by
changing the offset after the non-linear AD conversion. This is
so because the non-linear transfer function is
H(s) = 1-exp(-a*s)
by design, and neglecting the offset, the relation between the
non-linear output (y) and the linear output (x) is exactly:
Y = 1024 * (1 - exp(-x/713)) / (1 - exp(-1024/713))
This law yields an increased accuracy of about a factor 2 near
the zero end of the scale. It is thus possible to obtain an
Z = -2 * 713 * ln(1 - y/(1024/(1-exp(-1024/713)))) = -1426 * ln(1-y/1343.5)
Then Z is an 11-bit linear output in the range 0...2047.
effective 11 bit accuracy on a linear scale after post processing
by applying the reverse law to the non-linear output:
