That's a very interesting diagram you linked to there! I do wonder how much
processing instruments like the i1 do before reporting the spectral data.
There's nothing unusual going on - the light is diffracted and directed
to a CCD sensor. The raw sensor readings have black subtracted from them,
and are then re-sampled into calibrated nm bins (10nm or 3.3 nm for Argyll).
Calibration multipliers are then applied. That's about it.
(The Munki is slightly more complicated since it has a stray
light correction step.)
